IntroductionFor manufacturers flexible and eco-nomic production is the only way of en-suring that products meet the rapidlychanging needs of the customer.

Distributed automation structures areone of the factors needed for flexibleand economic production. Therequired flow of information is ensuredby interconnecting the various areas ofthe system over local area networks.

In the field of industrial communica-tions, networks complying with nationaland international standards enable the

exchange of information at all levels ofthe automation hierarchy.

PROFIBUS-DP fieldbus

The PROFIBUS-DP fieldbus has be-come established at the field level,where a high-speed response is re-quired and small amounts of data aregenerally exchanged.

PROFIBUS-DP is an open fieldbus sys-tem and is standardized to Europeanand international standards. This field-bus system is also the basis forPROFIBUS-PA, the fieldbus for processautomation.

Application

PROFIBUS is the network for the fieldand cell areas.

Three principle types are availabledepending on requirements:

PROFIBUS-DP PROFIBUS-FMS PROFIBUS-PA.

PROFIBUS-DP

The PROFIBUS-DP fieldbus featureshigh-speed communication with smallamounts of data and high system avail-ability.

It corresponds to the EN 50 170 stan-dard, Volume 2 with the DP protocolvariant. In addition, PROFIBUS-DP isthe basis for PROFIBUS-PA.

PROFIBUS-FMS

PROFIBUS-FMS is designed for com-plex communications tasks at the celllevel.

It corresponds to the EN 50 170 stan-dard, Volume 2, with the FMS protocolvariant.

PROFIBUS-PA

PROFIBUS-PA is the PROFIBUS ver-

sion for process automation.PROFIBUS-PA complies with the EN50170 standard, Amendment 2.

PROFIBUS-PA uses transmission tech-nology in accordance with IEC 1158-2.This transmission process can also beused for intrinsically safe applications.The communication protocols ofPROFIBUS-PA and PROFIBUS-DP areidentical. PROFIBUS-DP communica-tion protocol + IEC-1158-2 transmis-sion technology = PROFIBUS-PA.

Design

PROFIBUS-DP is different for activebus participants and passive bus par-ticipants.

Active nodes (masters)

Programmable controllers, e.g.S7-300/S7-400;M7-300/M7-400

PC-based Control Systems, e.g.WinAC

SIMATIC programming devicesand PCs

HMI devices Machine controllers, e.g.

SINUMERIK

Control systems, e.g. SIMADYN

Third-party PLCs

Passive nodes (slaves)

Distributed I/O stationsSIMATIC ET 200;

Controllers, e.g. S7-200/S7-300and S5-95U/DP;

Field devices such as drives or hu-man-machine interface units;

Field devices of process technology,e.g. SITRANS

Third-party field devices

The PROFIBUS-DP fieldbus can be in-stalled in two-wire cable, fiber optic orhybrid configurations

Mode of operation

he nodes in the network share thetransmission medium. A system istherefore required to control access to

the network.PROFIBUS-DP operates according tothe master/slave token passing ac-cess method, whereby only activenodes receive the right access the net-work. The right to access is transferredby passing a token from one master tothe next. If there is no request to send,the token is passed on to the next mas-ter.

The passive bus nodes are polled di-rectly by the master module assignedto them.

Open interfaces for PROFIBUS-DP/

PROFIBUS-PAThe communication performancerequired for the short response timescannot be achieved using the usual

standard components.

Siemens has therefore developed sev-eral high-performance ASICs for inter-facing the PROFIBUS-DP.

These ASICs handle a significant pro-

portion of the communication. The in-terface modules supplied for masterand slave applications are based onthese ASICs.

Integration centers

The integration centers support fielddevice vendors by providing adviceprior to and during development, aswell as performing the required integra-tion tests.

They also provide additional informa-tion on ASICs, interfaces and develop-ment kits.

The addresses of the Integration Cen-ters are shown in page 9.

Application

The PROFIBUS ASICs facilitate theconnection of third-party componentsand systems to the PROFIBUS field-bus.

Quick reaction times for thePROFIBUS-DP, which are required fortransmission rates of up to 12 Mbit/s,can only be achieved by using theseASICs.

Various ASICs are available for differ-ent functional needs and applications.

Master-ASICs

The ASPC 2 (Advanced Siemens

PROFIBUS Controller) is an intelligentcommunications chip for master appli-cations. This ASIC is suitable for use inmaster interface modules for connec-tion to PROFIBUS-DP and PROFIBUS-FMS. The maximum transmission rateis 12 Mbit/s for PROFIBUS-DP.

Intelligent Slave-ASICs

The SPC 3 (Siemens PROFIBUS Control-ler) is an intelligent communications chipfor slave applications. It enables con-nection to PROFIBUS-DP. The maximumtransmission rate is 12 Mbit/s.

Slave ASIC with processor coreThe DPC 31 combines the functionsof the SPC 3, SPC 41 and an 8031processor in a single chip. The DPC 31makes available a DP slave controllerwhich is highly flexible and can there-fore be used in an enormous variety ofapplications.

The DPC 31 is particularly suitable foruse in intrinsically safe applicationsbecause of its low-power system. Itenables connection to PROFIBUS-DP,PROFIBUS-FMS and PROFIBUS-PA.

With the SIM 1 the DPC 31 offers an

integrated compact solution for con-necting a PROFIBUS-PA using a trans-mission procedure according to IEC1158-2.

The maximum transmission rate is12 Mbit/s for PROFIBUS-DP and31.25 kbit/s for PROFIBUS-PA.

Simple Slave-ASICs

The SPM 2 (Siemens PROFIBUS Multi-plexer) is a single-chip solution for sim-ple slave applications. The maximumtransmission rate is 12 Mbit/s.

The LSPM 2 is, like the SPM 2, a single-chip solution for simple slave applica-tions, but its compact package makesit particularly suitable for applicationswhere space is at a premium. The max-imum transmission rate is 12 Mbit/s.

Operation

The ASICs handle a large part of the

communications tasks between thebus node and the network.

The ASICs of the SPM range (SPM 2and LSPM 2) handle all communica-tions tasks completely independently.The correct signals only need to beapplied to the pins. An additional pro-cessor or firmware is not required.

The ASICs of the SPC range (SPC 3,SPC 41, DPC 31 and ASPC 2) areequipped with a processor interface.They require additional firmware for theinterface between the ASIC and the ap-plication.

FirmwareThe firmware is installed in a processoron the interface module or in the fielddevice. The functions of the fielddevice are included via the call inter-face.

The scope of the firmware depends onthe ASIC.

Delivery arrangements

The ASICs can be obtained through theworldwide distribution network ofSiemens AG. Quantities of 5 ASICs orover can be ordered for testing.

For series production, only multiples ofan ASIC packaging unit (tray) are pos-sible. The number of ASICs per pack-age depends on the type of ASIC.

Please refer to the technical specifica-tions on page 16 for more details onpackaging units.

Application

The ASICs SPM 2 (Siemens PROFIBUSMultiplexer) and LSPM 2 (LeanSiemens PROFIBUS Multiplexer) aresingle-chip solutions for simple slaveapplications. Examples include sen-sors and actuators such as switches,indicators and thermocouples. TheASICs enable connection to thePROFIBUS-DP fieldbus.

The smaller package makes theLSPM 2 particularly suitable for use inapplications where space is at a pre-mium.

The maximum transmission rate is12 Mbit/s.

The IM 184 interface module is imple-mented with the ASIC LSPM 2.

Design

The SPM 2 has 64 input/output bits. It isaccommodated in a PQFP packagewith 120 pins.

The subdivision of the input/outputpoints into inputs and outputs is config-urable. Pins are also provided on theASICs for diagnostic information.

The SPM 2 handles the complete datatraffic independently. An additionalmicroprocessor and firmware are notrequired.

It is thus possible, using a small num-ber of external components, to imple-ment a simple connection to thePROFIBUS-DP fieldbus.

The LSPM 2 has the same functionalityas the SPM 2, except that it only has 32input/ output bits. It is accommodatedin a compact MQFP package with 80pins.

Operation

The SPM 2 and the LSPM 2 handle thebus protocol fully independently. Thepins only need to be connected to theinput /output signals and bus cables.

The SPM 2 and the LSPM 2 operate asslaves on the PROFIBUS-DP network.When they receive an error-free mes-sage frame from the master, they gen-erate the requested reply framesindependently.

Firmware

Firmware (in C source code) is sup-plied as an interface between the reg-isters of the SPC 3 and the application.

The firmware is operated on the pro-cessor of the field device and providescall interfaces for simple integration ofthe application.

The firmware consists of approximately4 to 24 Kilobytes and can also be usedforIM 182-1 and IM 183-1 interface mod-ules.

The firmware is not absolutely neces-sary for the operation of the SPC 3 withthe DP standard functions, since theASICs registers are fully documented;however, the firmware enables the userto save time which he would otherwisebe required to spend for developmentwork.

The firmware is required for the use ofthe additional DP functions DPV1(read/write data set).

Application

The IM 183-1 interface module enablesthe connection of a third-party deviceas slave to PROFIBUS-DP.


The IM 183-1 is designed for intelligentslave applications.

Design

The IM 183-1 interface module consistsmainly of the SPC 3 ASIC, the 80C32microprocessor, an EPROM and RAM

memory and an RS 485 interface forconnection to PROFIBUS-DP.

An RS 232 interface is also provided onthe module for the connection of devic-es with an RS 232 interface, such asPCs, to the PROFIBUS-DP fieldbus.

The SPC 3 ASIC is controlled by a48 MHz oscillator chip.

The interface is as small as a chequecard and suitable for face-to-facemounting.

Operation

The integrated SPC 3 ASIC handles thebus protocol fully independently.

Communication with the host systemtakes place via the address and databus which are routed to the connectorstrip. Data exchange is handled by theuser program.

The 80C32 processor enables the ad-ditional integration of applications.

Firmware

Firmware (source code in C program-ming language) is supplied as an inter-face between the registers of the SPC 3and the application.

The firmware is operated on the micro-processor and provides call interfacesfor simple integration of the application.

The firmware contains approximately4 to 24 kilobytes including examples.

The firmware is not absolutely neces-sary to operate the IM 183-1 interfacemodule with the DP standard functions,since the registers of the ASICs SPC 3are precisely documented. The firm-ware enables the user to save time hewould otherwise require for develop-ment work.

The firmware is required for the use ofthe additional DPV1 DP functions (read

/ write data set).

Development of Slaves

The purpose of the development kit isto develop a PROFIBUS slaves withASIC SPC3 and LSPM2.

Similarly, it is possible to developPROFIBUS slaves directly with theIM 183-1 or IM 184 (as a piggy-backunit in your own electronics).

In order to establish a small, runningPROFIBUS network, you must plug themaster interface module IM 180 into thecarrier plate IM 181, and install it in aPC (ISA slot). Then, connect it with theslave interface module IM 183-1.

The simulation software lets you assignparameters to the IM and control theslaves. As a result, you can quicklybecome acquainted with the designand functions of the field busPROFIBUS-DP.

The simulation software is installed on

the PC and enables you to control andquery the slaves through the Dual-Port-RAM of the IM 180. In the process, di-agnostic data of the slaves and inputscan be read, and slave outputs be set.

The program examples exist in sourcecode, and are well-documented.

Based on the examples, you can devel-op your own functioning software andhardware.

Master systems with IM 180

The IM 180, and the simulation soft-ware constitute an operative

PROFIBUS master. Based on this, youcan quickly develop a master applica-tion.

Proprietary master systems

If the hardware basis is not the IM 180 in itsoriginal condition (piggy back), then youneed the ASPC2 master firmware set, withcorresponding licence. This software isavailable in object code and in sourcecode. The software was designed for the80C165 processor.

The master licence and the firmware is notincluded in the development kit.Additional information is available inthe integration centers.

Functions

The development kit contains all com-ponents required to develop aPROFIBUS slaves with ASICs DPC31and SIM1.

The program examples exist in sourcecode and are well documented. Thehardware configuration is documentedwith circuit diagrams.

The CP 5613, which is included in thedelivery, must be installed in a PCI slotin the PC. Then, install the demo soft-ware (WinNT 4.0 required), to obtain afunctioning PROFIBUS-DP master. Usethe configuration tool "COMPROFIBUS" to assign parameters to theCP 5613 and to the PROFIBUS config-uration (with DPC31 board)".

If you intend to develop a PROFIBUS-DP slave to RS 485, you must couplethe DPC31 board to the PC master byusing the copper PROFIBUS cableincluded in the delivery.

If the line consists of optical cables,use the optical bus terminal (alsoincluded in the delivery) in order toconvert the interface to fiber optics.The accompanying fiber optic cablemust be connected to the optical inter-

face of the DPC31 board.

If the line is a PROFIBUS-PA line, theDPC31-Board must be connected overa DP/PA coupler. To achieve this, thesupplied PROFIBUS-DP cable must beplugged into the DP/PA coupler, and

the supplied blue PROFIBUS-PA cablemust be wired from the DP/PA couplerto the PA port of the DPC31 board. ThePROFIBUS-PA devices must be config-ured with the supplied PDM software.

The PROFIBUS DP/PA coupler(required if you wish to developPROFIBUS-PA applications) convertsthe PROFIBUS-DP technology toPROFIBUS-PA. It is not included in thekit and must be ordered separately.

The example application is stored inthe firmware EPROM of the DPC31boards, and starts to communicate withthe master once the cables are con-nected properly.

the software enables you to edit thefunctions included in the example, e.gby changing the limit values.

Based on this operative example youcan develop your own hardware andsoftware.
