Chapter 1 Introduction

The Series 90t 30 Genius Communications Module (IC693CMM301) is an intelligent

mod ule that pr ovides au tomatic, global data comm un ications between a Series 90-30

PLC and u p to 7 other devices on a Genius bus.

Global Data is data that is transm itted automatically and repeated ly, allowing the

formation of a shared database. A Genius Commu nications Modu le can exchange up to

a tota l of 256 bits (32 bytes) of Global Data.

computer, both of wh ich can be u sed to configure th e Series 90-30 PLC and GCM. The

GCM can monitor inpu t data from I/ O d evices; how ever, it cannot control I/ O d evices.

Other Genius Options for the Series 90-30 PLC

There ar e two other Gen ius m odules for the Series 90-30 PLC:

H The Enhanced Genius Communications Module (GCM+). The GCM+ can exchange

up to 128 bytes of Global Data with u p to 30 other devices on the bus. The GCM+

provides diagnostics information an d can potentially op erate without a h ost PLCprogram . The GCM+ mod ule cannot be installed in the sam e Series 90-30 PLC as a

GCM mod ule. See app end ix B for a comp arison of the features of the GCM and

GCM+.

H The Series 90-30 Genius Bus Controller. The Bus Controller can exchange up to 128

bytes of Global Data and/ or I/ O control data. It can be used to interface the Series

90-30 PLC to Genius I/ O Blocks, Remote Dr ops, and Field Control I/ O Stations, as

well as other types of controllers. A Bus Controller cannot be installed in th e same

Series 90-30 PLC as a GCM module.

Module Removal

The modu le can be removed w ithout pow ering down th e commu nications bus,

provided the incoming and outgoing Serial 1 wires have been connected to on e terminal

and the Serial 2 wires have been connected to one term inal. If this has been done, do

not disconnect the bus cable or any term inating resistor. Remove the Term inalAssembly from the front of the Genius Comm un ications Modu le carefully. Avoid contact

with exposed cable wiring. Place the Term inal Assembly, with th e bus w iring still

attached , in a pr otected location.

Caution

If exposed w iring comes in contact with conductive material, data on

the bus may be corrupted, possibly causing the system to shut down.

If the rest of the bus is powered d own, the bus w iring can be removed from the mod ule.

To remove the mod ule:

1. Locate the release lever on the bottom of the module. Firmly press it up toward the

module.

2. While holding the modu le firmly at the top, continue fully dep ressing the release

lever and swing the module upw ard.

Bus Cable SelectionThe Genius bus is a shielded twisted-pair wire, daisy-chained from block to block and term inated at both

end s. Proper cable selection is critical to successful operation of the system.

Each bus in the system can be any cable typ e listed in the table below. Do not mix cables of different imp edan ce,

regard less of cable run length . Do not mix cable types in long and /or noisy installations.. Other, small-size twistedpair shielded wire of unspecified imp edance can be used for short runs of 50 feet or less, using 75 ohm

terminations. Selection of wire type m ay be limited by local and national codes an d ind ustry standards. Consult

the cable manufacturer to deter mine the cables suitability for a particular type of installation.

Conserv ative wiring practices and national and local codes require ph ysical separa tion between control cir-

cuits and pow er d istribution or m otor power. Refer to sections 430 and 725 of the N ational Electric Code. Also

refer to App endix A for more detailed information about the bu s.

Using Other Cable Types

The cable types listed in the preceding table are recommen ded for use. If the cable types

listed above are no t available, the cable selected mu st meet the following gu idelines.

1. High quality construction. Most imp ortant is uniformity of cross section along the

length o f the cable. Poor qu ality cable may cause signal distortion, and increase the

possibility of damage du ring installation.

2. Precision-twisted shielded wire of EIA RS422 standard type, having a uniform

nu mber of tw ists per un it of length. In a catalog, this type of cable may also be listed

as twinaxial cable, data cable, or compu ter cable.

3. Relatively high characteristic imp edance; 100 to 150 ohms is best; 75 ohms is the

minimum recommended.

4. Low capacitance between wires, typically less than 20pF/ foot (60pF/ meter). This

may be accomplished by inn er dielectrics of foamed type, usu ally polyprop ylene or

polyethy lene, hav ing a low d ielectric constant. Alternatively, the cond uctors may be

spaced relatively far apart. Lower impedance types have smaller crosssections, and

prov ide easier wiring for shorter total transm ission d istances.

5. Shield coverage of 95% or more. Solid foil with an overlapped folded seam and d rain

wire is best. Braided copper is less desirable; spiral w oun d foil is least desirable.

6. An outer jacket that provides approp riate protection, such as water, oil, or chemical

resistance. While PVC ma terials can be u sed in man y installations, Teflon,

polyethelene, or polypropylene are u sually more du rable.

7. Electrical characteristics: cable manu facturers information abou t p ulse rise time and

NRZ d ata rate is useful for comp aring cable types. The Genius bit consists of three

AC pu lses; the equ ivalent NRZ bit rate is about three times as great.

For assistance in selecting a cable type, please consult your local GE Fanuc application engineer.

Bus Length

The m aximum bus leng th for shielded , twisted-pair cable is 7500 feet. Some cable types

are restricted to shorter bu s lengths. If the app lication requ ires greater bus length , fiber

optics cable and mod ems can be used . For more information , see the Genius I/O System

and Communications M anual.

Baud Rate Selection

The bus length d etermines which baud rate may be selected. A Genius bus can operateat one of four bau d r ates: 153.6 Kbaud stand ard , 153.6 Kbaud extend ed, 76.8 Kbaud, or

38.4 Kbaud. The bau d r ate selected sh ould be ind icated on all dev ices, especially if

different busses in the facility use d ifferent baud rates. The bau d ra te mu st be configured

using a H and-held Programm er or the system configuration software.

Note th at in n oisy environmen ts, 153.6 Kbaud extended provides improved noise

imm un ity with little effect on bu s scan time. If a system is experiencing excessive

blinking of the bus controllers COMM OK light, or if the I/ O blocks I/ O Enabled LEDs

go off frequently, 153.6 Kbaud extended shou ld be u sed.

If you need to install the terminating resistor across different terminals than those u sed

for the signal wires, attach jumper wires between the signal wire terminals and the

Wiring Guidelines

Four types of wiring may be encoun tered in a typ ical factory installation:

1. Power wiring the plant power distribution, and high pow er loads such as high horse-

power motors.

2. Control wiring usually either low voltage DC or 120 VAC of limited energy rating.

Examples are wiring to start/ stop sw itches, contactor coils, and m achine limit switches.

This is generally the interface level of the Genius d iscrete I/ O.

3. Analog wiring transducer outputs and analog control voltages.

4. Communications and signal wiring the commu nications network that ties everything

together, includ ing computer LANs, MAP, and the Genius comm un ications bus.

These four typ es of wiring shou ld be separated as m uch as p ossible to redu ce the hazardsfrom insu lation failure, miswiring, and inter action (noise) between signals. A typical PLC

system m ay requ ire some mixing of the latter three types of wiring, particularly in cramped

areas inside m otor control centers and on control p anels. In general, it is acceptable to mix the

Genius bu s cable with the I/ O wiring, as well as associated control level wiring. All noisepickup is cum ulative, depend ing on both the sp acing between w ires and the d istance span

they r un together. I/ O wires and Genius bus cable can be placed ran dom ly in a w iring trough

for lengths of up to 50 feet. If wiring is cord-tied (har nessed), do n ot includ e the bus cable inthe h arness, since bind ing wires tightly together can dam age some cable types.

Wiring external to equipm ent and in cable trays should be separated following N EC practices.

Lightning Transient Suppression

Running th e bus cable outdoors or between bu ildings m ay subject it to lightning

transients beyon d th e 1,500 volt transient rating of the system . Installing cable

un derg round red uces the probability of a direct lightning strike. However, bur ied cables

can pick up hun dred s of amp eres of cur rent wh en lightning contacts the groun d nearby.

Therefore, it is important to p rotect the installation by includ ing sur ge pr otectors onun dergroun d data lines. The cable shields shou ld be grou nd ed d irectly. Surge

supp ressors and spark gaps should be u sed to limit the voltage that might appear on the

signal lines. It is recomm end ed to install two (only) silicon su rge sup pr essors or spark

gaps to control transients of 1 to 25 Kilovolts from 100 to 1000 amp s or m ore. Thesedev ices should be installed close to the entrance of the bus to the outd oors.

Silicon Surge Sup pressors are available man y sources, includ ing Clare/ General

Instru men ts and Motor ola, For information abou t this product, in the US contact Lucas

Indu stries Incorporated , 5500 New King Street, Troy, Michigan 48098. Spar k gap s are

available from Clare. Refer to the vend or s literatu re for installation details.

In extreme situations such as totally-isolated p ower systems, add itional protectionagainst lightning damage should be p rovided by add ing surge supp ressors for groups of

I/ O blocks. Such sup pressors should be installed from incoming pow er leads to ground

(enclosure basep late/ block case where leads enter the enclosure).

A device specifically designed t o protect the Geniu s bus is available from CO NTROL

TECHNOLOGY, 835 Hwy 90, Hancock Square Suite 10 (P. O. Box 2908), Bay Saint Louis, MS

39520. (tel 601 466 4550, fax 601 466 4553). Contact them for application information. The

devide m ust be used in combination with p ower line suppression to fully protect the

system.

Installing the Hand-held Monitor D-Shell Connector on the Bus

You h ave the op tion of installing the D-shell connector that is sup plied w ith the

Hand -held Mon itor. You will need a m oun ting p late (IC660MPH509) for th is type of

installation.

1. Using the mounting plate as a template, cut an opening in the panel for the mating

connector. Also drill two holes for the moun ting hard ware.

2. Attach the mounting plate and mating connector to the panel using the mounting

hardware sup plied.

3. Secure the two end s* of the serial bus cable to the back of the panel using strain

relief brackets.

4. Strip the ends of the wires. Twist the two Serial 1 wires together and attach them to

pin 5 of the connector. Twist the Serial 2 wires together and attach them to p in 9.

Similar ly, attach the Shield w ire(s)* to p in 4.

The following illustra tion show s connections for incoming an d ou tgoing serial bus

cable. As with other d evices, the HH M connector may be at either end of its bus. If itis, there w ill only be one bu s cable attached.

Global (%G) Memory in the Series 90-30 PLC

A portion of the Series 90-30 PLCs mem ory is reserved for Global Data. This bitoriented

memor y uses the prefix %G. The amoun t of %G memor y available depends on the CPU

type. For example, the mod el 311 CPU has 256 bits (32 bytes) of Global Data mem ory and themodel 331 CPU has 1280 bits (160 bytes).

%G mem ory is divided into 4byte increments, each of which corresponds to a Device

Nu mber from 16 to 23 on the bu s. The %G locations and defau lt data length s are listed below.

The GCM u ses this %G m emory for both send ing and receiving Global Data.

If a GCM is set up to send Global Data, it will broad cast some or all of the data in %G

memor y to all other devices on th e commun ications bus.

Unless this uses up the PLCs entire %G mem ory space, the modu le can also receive incoming

Global Data from u p to seven other d evices on the bus. This da ta will be placed into the

app ropriate %G mem ory locations.

Global Data Lengths

The amoun t of Global Data that can be sent by each GCM depend s on how many GCMswill be sending Global Data. For example, a bus might hav e four GCMs, with one

How the Devices on the Bus Handle GCM Global Data

One Genius commu nications bu s can serve up to 32 devices, includ ing interface mod ules

like the GCM, Genius I/ O blocks, and Genius H and -held Monitors. Any combination of

these dev ices may be pr esent on a bu s wh ich w ill be used for Global Data.

GCM Receives Global Data

Any bus interface mod ule that w ill send Global Data to the GCM m ust be configured to

Additional Considerations

A GCM+ or Bus Con troller mod ule in anoth er Series 9030 PLC p laces

the d ata in the memor y location specified wh en that mod ule is

configured. If a GCM+ modu le does not need all of the d ata, a message

offset and length can be specified. However, a Bus Con troller mustreceive all of the data .

To tran sfer Global Data with a GCM, the configu ration of the Series

90-70 PLC mu st be set up to specify the Gen ius Com mu nications

Module (IC693CMM301) as a d evice on the bus.

To transfer Global Data w ith a Series Six PLC, the Series Six Bus Cont roller

mu st be catalog nu mber IC660CBB902F/ 903F (firm ware version 1.5), or later.

For the Series Six PLC, Global Data mu st be initialized by send ing a Write

Configuration comm and to that Bus Controller. The comm and m ust specify

a location in register memor y where the Global Data to be sent w ill begin.

The Series Six PLC autom atically receives Global Data sent by any GCM

wh ich send s it. This da ta will be placed in register memor y locations that

correspond to the sending devices Device Nu mber.

It is important to be sure th at registers correspond ing to Device Nu mbers

that w ill send Global Data are not used for anything else in the program ,

even if the Series Six PLC will not m ake use of the Global Data it receives. If

a device using one of the above Device Num bers sends Global Data, it w ill

always be received if the Series Six PLC app lication p rogram open s a

wind ow to the Bus Controller (using a DPREQ or WINDOW instruction or

the Computer Mailbox).

If the Series Six PLC is set up for Expan ded I/ O ad dr essing, registers R001

throu gh R0016 are used for Auxiliary Ou tpu t Table references AO0001 to

AO0256. Auxiliary outp uts that corresp ond to Device Nu mbers thatbroad cast Global Data should not be used.

A Series Five PLC can send Global Data to th e GCM. The Series Five Bus

Controller that w ill be used m ust be assigned a Device Nu mber from 16 to 23

(using the Logicmaster Five software, or an O pera tor Interface Unit).

The Series Five PLC au tomatically receives Global Data from an y GCM th at

A compu ter on the bus can exchan ge Global Data with a GCM. The

compu ter s Bus Con troller (a PCIM or Q BIM) places Global Data sent by

the GCM into a mem ory location that corresponds to the Device Nu mber

of the GCM m odu le. The computer s application program is responsible

for transferring Global Data between its CPU and the PCIM or QBIM.

I/ O blocks (controlled by an other host) can be present on the bus. Their

opera tion will not interfere with Global Data transfer.

If a block were assigned a Device Number from 1623 and the Genius

Communications Module were configured to receive from that Device

Nu mber an amou nt of data equal to the number of inpu ts from the

block, the Series 90-30 PLC could m onitor the inp ut d ata. However, it

could not send an y outp uts back to the block.

It is possible to use inp utsonly blocks on a bu s w ith a Series 90-30 PLC

mon itoring inpu t data , and n o other host (or the Series 90-30 PLC)

send ing ou tpu ts. How ever, a blocks I/ O Enabled LED, wh ich reflects

the presence of comm unications from the host, would never light

because the block would not receive such communications from theSeries 90-30 PLC.

A Genius Han dheld Monitor can be u sed to d isplay bus status

Relationship Between the Bus Scan and the CPU Sweep

The bus scan is comp letely indepen dent of the CPU Sweep. The CPU sweep is the

Series 9030 PLCs regular cycle of program execution, I/ O up date and oth er tasks. The

Genius Commu nications Module acts as the interface between th ese two asynchronousactivitiesthe bus scan and the CPU sw eep. It stores Global Data it has received from

other d evices on the bu s. In the following example, two devices (18 and 22) send Global

Data on the bus. Each mod ule broadcasts its Global Data wh ile it has the bus token. The

Global Data is received by a Gen ius Com mu nications Modu le in a Series 9030 PLC.

After the CPU scans inpu ts, it executes the application pr ogram . This pr ogram can u se the

new Global Data it has received from other m odu les on the bus. If it will send Global Data, it

mu st includ e logic capable of placing d ata into the %G mem ory location assigned to its

Genius Commu nication Module wh en the PLC upd ates outpu ts, after the app lication

Continuing th e same examp le, after executing its program the CPU send s new Global

If prog ram execution time is slower th an bu s scan time, it is possible that some incoming

Global Data migh t chan ge before it is picked up by the CPU. It is important to be sure

that th e data w ill not be sent so briefly that it will be missed.

If prog ram execution time is faster than bus scan time, the CPU m ay p rocess the same

data repeatedly.

To the time requ ired to service all devices, add th e time requ ired for all the Global Data

that will be send by the Genius Commu nications Modu les on the bus.Each Global Data

message will be sent every bus scan. Therefore, the total size in bytes of each message

contributes to the scan time. Each Global Data m essage also includ es a 1byte Start of

Block (SOB) and a 1byte End of Block (EOB). For examp le, if tw o devices on the bus

EACH sent a 4byte Global Data message, the total would be:

4 byte message + 2 bytes (SOB and EOB) = 6 bytes

4 byte message + 2 bytes (SOB and EOB) = 6 bytes

Global Data addition = 12 bytes

The time required to transmit the data depend s on the baud rate. After add ing together

the m essage bytes for Global Data, multiply the total by on e of the following

transmission rates:

0.0715mS/ byte for 153.6 Kbaud (either stand ard or extended )

0.143mS/ byte for 76.8 Kbaud0.286mS/ byte for 38.4 Kbaud

Example:

In this examp le, there are 8 Series 9030 Genius Com mu nications Modu les on the bu s

(and no other d evices). Each mod ule is send ing 4 bytes of Global Data. The baud ra te

on the bus is 153.6 Kbaud standard . Scan time on this bus w ould be:

8 Genius Communications modules (8 x 1.09) 8.72mS

24 unused Device Numbers (24 x 0.026) 0.62mS

8 Global Data messages , 4 bytes each ((4 + 2) x 0.0715) 3.43mS

Total bus scan time = 12.77mS

Estimating Data Response Time

For app lications w here it is imp ortant to know how long it will take for on e mod ule to

send Global Data to another and to receive a reply based up on that d ata, you can

estimate response time by ad ding together the m aximu m time that may be requ ired foreach p ortion of the inpu t to outp ut cycle.

The worst case turnarou nd response time can be estimated by calculating:

2(Tcpu1) + 2(Tbus) + 2(Tcpu2)

Tbus and Tcpu are explained below.

Bus Scan Time (Tbus)

Tbus is the time that it takes for a complete bus scan (token rotation from 0 to 31). This is

calculated by add ing all of the bus scan time contribu tions of dev ices on the bus and

Global Data, as discussed in the preceding pages. The scan time contributions of other

types of devices that may be on the bus are listed in the Genius I/O System Users Manual.

Program Execution Time (Tcpu)

A Genius Communications module stores incoming Global Data where it can be

accessed by the app lication program cu rren tly executing in the CPU. If the CPU services

the mod ule shortly after it receives new input data, the inpu ts will be read into CPU

mem ory quickly. However, if the mod ule has just been serviced by the CPU, another

CPU sweep must elapse before the newlyreceived Global Data is read.

Sending Data in Reply to Global Data Received

If the application p rogram will send Global Data in respon se to Global Data it has

received, one add itional CPU sw eep w ill be required for the app lication p rogram toprocess the data.

The same relationship app lies to send ing Global Data on the bu s. If Global data changes

as a result of Global Data received, the Genius Comm un ications mod ule will send it on

the bus du ring the next bus scan. If the token has just pa ssed, the Global Data must w ait

up to the length of the bus scan before the mod ule receives its next turn on the bus.

at 153.6 Kbaud stand ard wh en shipped from the factory.

Baud r ate mu st be selected on the basis of cable type (see the table in chapter 2) and the

following considera tions.

1. If the cable length is less than 2000 feet, either 153.6 Kbaud standard or 153.6 Kbaud

extended can be used . The use of 153.6 Kbaud extend ed is recommended , especially

if the system w ill include a dua l bus with Bus Switching Mod ules.

2. If cable length is between 2000 and 3500 feet, select 153.6 Kbaud extended.

3. If the cable length is between 3500 and 4500 feet, select 76.8 Kbaud.

4. If the cable length is between 4500 and 7500 feet, you mu st select 38.4 Kbaud . This

data rate only supp orts a maximum of 16 device on the bus.

5. If there are any older Genius produ cts on the bus (catalog nu mbers IC660CBDnnn,IC660CBSnn n, IC660CBAnnn , IC660HH M500, or IC660CBB900/ 901), the bus mu st

Electrical Interface

The Genius serial bus u ses computer grade twisted pa ir data cable. The half dup lex token

sequence u sed requ ires only a single pair since at any time only one station is transmitting

and all others are receiving. All stations m ust receive in order to track the present tokenvalue and take their appropriate tur n on the bus, regardless whether the data is to be used

locally. The tran smit sequence is the same as th e serial bus address (SBA) set into each

location during configuration. A simp lified interface circuit is show n below:

Signal coupling to the bus is via a high frequency, high isolation pulse transformer. This

permits the bu s and the local logic to be at d ifferent voltage levels. The pu lse w aveforms are

bipolar (see next section below) to reduce DC baseline offsets in the w aveform.

The daisychained bu s is show n on the left in the above illustra tion. The SER 1 and

SER 2 lines are merely tapp ed at th e intermediate locations along the bu s. These

connections mu st be consistent since the signal is polarized . The shield of the cable is

broken into segmen ts at each location. Each shield segmen t is DC grou nd ed at one end(SHIELD OUT), and term inated with a small capacitor at the other (SHIELD IN). The

segmenting breaks up long ground loop paths. The capacitor termination redu ces

common m ode n oise from high frequency pickup , while preventing large ground loop

currents in the shield at low frequencies.

The alternately switching transistors produ ce a negative pu lse followed by a positive

pu lse across SERIAL 1 relative to SERIAL 2. The bit wav eform is a series of these pulses,

as will be shown later. The transform er pr ovides isolation (2500 volts test) between the

bus an d th e local logic, per mitting th ese to be at d ifferent voltages. The internal resistors

in each line p rovide current limit and some term ination function du ring transmission.

The balanced (differential) signals on the tw isted pair p rovide high noise imm unity d ue

to the magnetic (H field) cancellation effect of the twisting, as well as electric (E field)

redu ction by th e shielding. Most remaining noise pickup is comm on mod e: the

transformer provides a h igh common mod e noise rejection by looking only at the

differential signal across the SER 12 lines. The two input com parators d etect the

positive polarity inpu t pu lses separa tely from th e negative; these are sent to a custom

interface logic chip w hich digitally filters these for timing and sequence, then

reconstru cts the NRZ digital data. Voltages between th e two th resholds ar e ignored. This

filtering, and the high inpu t threshold if the comparators, are high ly effective in rejecting

both ran dom imp ulse noise and low level line reflections. Finally a CRC6 checksum

check is perform ed before the d ata is sent to the local processor (not show n).

Serial Bus Waveforms

The actual waveforms seen on the cable depend on the cable imp edance and the

distance from th e station presently tran smitting. A data 0 is a series of three AC pulses,

while a 1 is no pu lse.

Use caution wh en connecting instrumentation to the bu s. A differential probe or a

summ ation of two p robes relative to groun d is required. Inadvertent ground ing of one

side of the bus can cause loss of data or data errors.

The pulse frequency is three times the baud frequency, for example 460.8 KHz at 153.6 Kb.

The peak tran smitted vo ltage Vp an d the receiver threshold s Vr are per the electrical

specification above. The peak voltages measu red w ill decline with d istance along the

cable from the transmitting station, so different stations will have var ying amplitud es.

The wave shape w ill also become more rou nd ed w ith distance.

The minimum amp litud e pu lses seen during a 0 should exceed the receiver threshold

Vr of 900 millivolts by 50% (abou t 1.4 volts) for best reliability. An occasiona l pu lse at or

below the th reshold m ay still not cause the bit to be missed, du e to a voting algorithm in

the logic, however.

Likewise, no pu lses greater than Vr shou ld exist du ring logic 1 interv als. Occasional

extra pu lses during this interval are also rejected by the logic.

Line reflections will show u p as notch distortion d ur ing the pu lse or low level pu lses

du ring 1 intervals, and their app earance is synchronized to the baud frequency. These

cause no p roblem if they d o not cause violation of the amp litude criteria of the pr evious

paragraphs.

The Serial 1 and Serial 2 lines should alw ays have a termination resistor equal to the

characteristic imp edan ce of the cable connected at each extreme en d. When testing aGenius block or other d evice using a Han d Held Monitor, wh en no serial bus is present,

a term inating resistor will improve integrity. 75 Ohm s is recomm end ed.

Effect of Long Cables, Repeaters, or Unspecified Cable Types on

Maximum Length Bus

Three effects limit the maximum length bus available at any baud rate:

1. Voltage attenuation

2. Waveform d istortion (frequency dispersion)

3. Propagation delays

Attenuation

The transmitter outp ut levels and receiver thresholds determ ine the m aximu m

attenuation that can be tolerated. For Genius products, this is the principal determinant

wh en using recomm ended cable types.

Distortion

Waveform distortion is du e to the limited bandw idth of wire m edia, which causes the

various frequency components of a p ulse waveform to travel at d ifferent speeds an d

thu s arrive separa tely in time (called dispersion). As a result, the received p ulse app ears

round ed and distorted. The signal at the extreme end from the transmitter may look

round ed and skewed as shown below. Distortion is most apparent near the beginning

and end of a pulse train w here in may ap pear as a change in p hase or a frequency shift.

Critical timing for a logic 0 transmission is shown below in a m ore deta iled version of the

waveform:

Tw Tw

+Vr

Vr

Tp/2 Tp/2

Note the first and last ha lfcycle look w ider. The most critical to operation is the first full

cycle of the first start bit of the transm ission. Detection of this pulse establishes the timesynchron ization of the receiver to the incoming waveform. Missing this first pu lse does

not cause the data to be m issed, but m ay compromise the noise imm unity w ith respect

to extra or missing pu lses. The frequency of the AC pu lse is 3X the bau d r ate as noted

earlier. This means the nor mal period Tp(norm al) is:

H 2.17 microseconds at 153.6 Kb

H4.34 microseconds at 76.8 Kb

H 8.68 microseconds at 38.4 Kb.


45/50

A


The half cycle pu lse width, w hen m easured betw een the p ositive and negative receiver

thresholds, denoted as Tp/ 2 in the figure, will vary along the w aveform du e to

dispersion, and resembles a frequency shift.. The digital inpu t filter essentially is a band

pass filter w hich looks at the half cycle timing Tp/ 2, and the d uration above the

thr esholds, Tw. The limits ar e:

HTp/ 2 = 0.6 Tp(normal) maximum

H Tw = 0.188 Tp(norm al) min imu m

These measurements can be taken wh en evaluating the maximum length of an

un specified cable. Dispersion is m uch less of a prob lem w ith fiber optic links since the

med ia is mu ch wider band width , and th erefore has less distortion.

Propagation Delay

The p ropagation d elay is caused by travel time of the signal down the cable. Typical

signal velocity in d ata grad e cables is around 65 78% of the sp eed of light. This requires

abou t 3 microsecond s to travel a 2000 foot long bu s. This is abou t half a bit time at 153,6

Kb. This skew could affect the bu s access sequen ce since only on e bit of quiet bu s (skip)

time is usually allocated between transm ission of ad jacent add resses. (Refer to Bus

Access Time section below.) The signal m ust reach all dev ices on th e bu s within the

period of one bit. Propagation delay causes the u ltimate limitation in bu s length, even

with ideal media. Propagation speed throu gh fiber optic is not significantly different

than wire, and delays through the interfaces must be accounted for.

Serial Data Format

The Genius protocol is designed to prod uce maximu m throu ghpu t of data by using a

minimum overhead of control and synchronizing characters.

Each character is 11 bits long, comp rising a start bit (always 0), next a contro l bit,

followed by 8 bits of data, sent LSB first. The last bit is a stop bit, alw ays 1. Successive

characters are sent with no time space between them . The control bit is used to signal

the typ e of character being sent. A 1 ind icates a control character, and 0 a data character.

A minimum transmission is comprised of a start character, one or m ore data characters, and

a stop character. The Start character data contains the address and wh ether the

transmission is directed to a specific address or a broadcast to all. The End character contains

the CRC 6 checksum. More complex transmissions may have ad ditional start and en d of

block characters to break up the message into blocks of data (not to be confused with

Genius I/O Blocks). For example, a Bus Controller can send device specific messages

(blocks of data) to all devices on the bus during one transmission cycle.


46/50

A


Bus Access

All dev ices must receive the cur rent SBA and the stop character even though the d ata is

irrelevant locally. After the stop control character is received, each d evice on the bus

starts a timer. The time delay is equal to a skip time, times the d ifference between thedev ice Serial Bus Ad dr ess (SBA) and the last SBA received. The d evice will transm it after

the time delay if no other start bits are detected first. Thus each dev ice takes turn in

ord er of SBA. Unu sed SBAs result in longer t imes between messages. All devices must

detect m essages with in this skip time d elay. A bus collision (two sources transmitting

simultan eously) results if this sequence is missed. The skip time value is equal to one bit

period , except on the 153.6e rate, wh ere it is two bit period s long. The longer interval is

useful to accommodate the longer p ropagation delays du e to longer bus cables, or when

delays are introd uced by fiber optic or other repeaters, The worse case is when ad jacent

SBAs are p hysically located at op posite end s of a long bus. For examp le, assum e SBA 4

and 6 are at on e end of a 2000 foot bus an d SBA5 at the other, operating at 153.6s Kb.

When SBA 4 end character is detected, SBA6 immed iately starts timing 2 skip times (13

uSec) to start of its transmission. SBA5 receives the end character 3 uSec later, and starts

timing 1 skip tim e (6.5 uSec). Thus SBA 5 will start transm itting 9.5 uSec after SBA 4 qu it.

This allows 3.5 uSec for th e signal to get back to SBA6 to cancel its tran smission tu rn .

The 3 uSec transm ission d elay leaves only 0.5 uSec to do th is and avoid a collision

between SBA5 and 6.

Bus collisions result in m issing d ata or d etected CRC errors. Problems resulting from bu s

collisions can be fixed by not using (skipp ing) a SBA, resequencing SBAs in order along

the bu s, going from 153.6s baud to the 153.6e, or a lower baud rate.

Bus Errors Caused by Noise

Most capacitively- and m agnetically-coup led noise show s up as comm on mod e voltageon the bu s. The bus prov ides a 60 dB comm on mode rejection ratio. A noise spike above

1000 volts wou ld be required to corr up t the da ta. The bus receivers filter out corru pted

data and perform a 6-bit cyclic redun dan cy check to reject bad data. Corru pted signals

du e to noise show u p as m issed d ata rather than incorrect data. The bus continu es

operating to the maximum extent possible when bu s errors are detected; random bus

errors d o not sh ut d own commun ications. Bad data is rejected by the receiving d evice

and excessive errors are rep orted to the controller. Bus er rors are ind icated by flickering

of I/ O block and bu s controller LEDs. If excessive bus errors occur, the p roblem sh ould be

found and corrected.
