A maximum of 18 Process sections can be defined, access to 16 of these (1..16) can be configured via the OS. If the process Section is set to 0 (Zero) it is accessible from ALL other sections (often used for common systems). If the process Section is set to -1 (minus 1) it is hidden from ALL operator stations (could be used for node to node database elements or setpoint elements (eg: AOCs) which are then only adjustable from Engineering station. Refer to Project specific specifications to Design Rules for details.



3.4 Alarming and Event Handling

3.4.1 Alarm & Event Categories

There are 2 different types of alarm and events: System Alarm/Events System alarms include internal supervision of I/O, peripheral devices and database elements. In general all database elements are supervised (error treatment). For most db-elements the value for ERR_TR should be set to 2 (default is 0), this initialises event reporting and alarm handling in the Operator Station for signal errors and operator commands. Process Alarm/Events In addition to drive feedback signals to DCS, All output orders from the DCS are shown in the event list. To reduce the number of events and alarms (Operator Overload) the following rules will be followed:

Events and alarms will ONLY be generated at source. For drive feedbacks, ON/OFF (or OPEN/CLOSE), and for motor/breaker feedbacks TEST,

the eventing is achieved using the DIC/DIS database Elements VALUE_TR(eatment) property Refer to table on following pages.

The standard functionality of the APC PC/DB elements will create events for the remaining feedbacks and orders (such as Torque, Local, Disturbed etc.).

Where APC PC/DB elements are not used, events for all signals must be generated by using DIS and DIC database elements.

3.4.2 Concept for setting Limits of Analogue signals AC450

A basic design concept is that all analogue derived alarms are shown as a colour change on the appropriate Object Display. This is achieved by setting the following AIC database parameters: EN_L1=1 for Low alarm limit indication arrow to appear in analogue displays EN_L2=1 for Low-Low alarm (or trip) limit indication arrow in analogue displays EN_H1=1 for High alarm limit indication arrow to appear in analogue displays EN_H2=1 for High-High alarm (or trip) limit indication arrow in analogue displays LIM_1_TR=0 if no events are required, otherwise select an analogue specific value treatment eg: 201 LIM_2_TR=0 if no events are required, otherwise select an analogue specific value treatment eg: 202 Note that this colour change should only be used for Alarms and pre-alarms where the operator attention is required ( i.e. where an alarm is shown in the Settings list, PFuP, I/O-List etc.). Note: A setting of 0 for LIM1_TR or LIM_2_TR causes the analogue display to change to RED (without flashing) irrespective of the required alarm Priority. All switch points, alarms and trip settings are generated using COMParators writing to DICs and these DICs are given the correct priority and colour via the VALue_TReatment setting. For Hardware inputs, the COMParators and Limit settings can be defined in the same PC programs (1 through 4) used for the input signal at CONTRM Nr 33 or higher or in PC 7 through 9 (preferred method as PC1 can get too large to load into the controller) . Also refer to Section TX359H5 X X360HHardware SupervisionXT and X361HTAttachment 12: Analogue Limits for Hardware I/Os in AC450 TX for an example of a PC program for generating analogue limits.

3.4.3 PIDCONA Controller Alarming AC450

Deviation alarms (SP-PV) are internally generated within the PIDCONA and the alarm limit is set in the dBase element.



Only deviation alarms or internal faults are shown by a colour change in the PID Object Display.

3.4.4 Event handling of I/O-Signal and PC generated Alarms AC450

There are two priorities for alarm signals and one for events: Note that the numbers refer to the required settings in the Alarm and Event list on following pages

Priority 2 High Priority: These are displayed in red in the operator station alarm and event list. - Signals as pre-warning prior to trip - Signals that have caused a trip - Tripped status of main equipment / sub-systems.

Priority 3 Low Priority: These are displayed in yellow in the operator station alarm and event list. - All remaining process alarm signals

Priority 4 Events: These are displayed in green in the operator station event lists. - All status signals (ON, OPEN, ENGAGED etc.)

Signal alarms

System generated These are displayed in red in the Operator station alarm and event list. - Signal errors/POS Ind error, etc

3.5 KKS Naming of Signals ( Signal Codes) ALL non-communication database elements must be given a KKS Nr (do not use a Clear Text name). When not otherwise stated signal codes may be used for external (hardware I/O) or for internal signals In this section: n is numeric 0...9. c is character A...Z

3.5.1 For Analogue Hardware Inputs/Outputs, Conditioned & Calculated Signals

Main KKS Ext. Used for Notes XQ50 Analogue Input Hardware Input XQ60 Analogue Signal After 4-20mA Transmitter superv. XQ63 Analogue signal Error Input disturbance of XQ60 signal XJ50 Analogue Output Hardware output Ccnnn_ or Fcnnn_ or FFnnn or FUnnn

XJ60 Corrected or Combined value

Corrected Flow, Level,.. Analogue signal, 2oo3 etc.

Ccnnn_ or Fcnnn_ or FFnnn or FUnnn

XJ63 Error of Corr. or Comb. Value (2o3)

Corrected or Combined analogue disturb. Signal. Normally event FAILURE

XJ64 Error of one signal (1o3) Can include drift alarm! Normally event SEN UNEQ

XJ65 Drift between Comb values Analogue deviation between inputs exceeded, no BDQ included! Normally event DRIFT

XJxx Difference between Comb Limits

Difference between Limit outputs of individual signals used in a 2oo3 etc. where "xx" = same number as the supervised Limit (XHxx).

XJ01..99 Analogue Signal General calculated values

c & nnn is taken from the KKS of the main input signal The last 3 digits of the KKS Nr which is the result of 1oo2 or 2oo3 etc. signals will normally

be 9nn where nn is taken from the lowest number in the KKS of the input signals eg: The output of a 1oo2 using CF051_XQ60 & CF052_XQ60 would be CF951_XJ60

The output of a correction function using CF051_XQ60 & CP052_XQ60 would be FF951_XJ60

The 1st character in a KKS can be a character (permitted by KKS and required for some projects with more than 8 units (Note:0 is not used and 9 is reserved for common systems)

In general (unless otherwise defined in signal I/O List) Valve position signals have the same KKS number as the signal source i.e. the Valve KKS with signal extension as applicable from above table.

3.5.5 For a signal generated within Advant

Signals written to a database element: Unless the signal is hardwired and has been otherwise defined in a signal I/O list, the signal will normally take the KKS of the signal source DG, SEL, DRIVE, etc. plus a suitable signal extension. eg.: 11LAF40EA100_XA91.

Signals used internally in a PC program: These are given a NAME which is the KKS/Extension as described above preceded by I_. A clear text description may also be used. A combination of KKS and Clear Text may also be used. eg: I_11MAN10AA002_RCLS The KKS number prefix should be removed (to ease copying nodes) if signals do not require it. eg: I_MAN10AA002_RCLS

All Signals between pages of a PC program should be given names (exception is between the MOVES around type Circuits where the TC pins clearly identify the signal source).

3.6 AC450 Node to Node Communication Refer to X362HTAttachment 4: AC450 Node to Node Interface (Typical)TX

A minimum of 2 Sending and 2 Receiving DS's with the corresponding DATs is required in each node, for the communication to every other node of the same unit.

A direct node to node communication shall be used between nodes of different units. In each node, and for each unit, two PC programs are defined for the node to node

communication: Communications within same unit: PC10 for incoming signals, PC 90 for outgoing signals. Communication to other units: PC11 and PC91, PC12 and PC92 etc. This segregation is to enable unit for unit automatic generation of DS communications at a later date and to simplify node copying

Sending Node PC program (eg:PC90),: - There is one CONTRM for the communication to each receiving node. - All DS/DSPs between these 2 nodes are written in this CONTRM. - The structural element FUNCM (function module) will be used for further structuring of individual Datasets.

Redundant signals do not have to be sent over different Datasets.

3.6.1 Analogue Signals transferred between nodes

Note: The 1PSTP _ may be replaced by a characters explained below).

When 2 similar KKS have been configured in 2 different nodes, it is possible that OS may not recognize both KKS numbers. This case is usually found in node to node signals. To distinguish these 2 signals it is advised to use a letter in place 18 PthP KKS Character The suggested letters are ( G GT, W WSC, H HRSG, E- ELECT, B BOP, S ST).

3.6.3 DS Node to Node Communication:

DataSets (DS) are used for Data Transfer over MB300 between all AC450 nodes General naming template: e.g. 171802R

. Send or Receive 17 18 02 R

DS Name: 171802S SEND/RECEIVE - S NODE - 18 ID - 9

DS Name: 181701R SEND/RECEIVE - R NODE - 18 ID - 10

DS Name: 171802R SEND/RECEIVE - R NODE - 17 ID - 9

DS Name: 181701S SEND/RECEIVE - S NODE - 17 ID - 10

Node 17 Node 18

The associated DATs ( .ILnn, Rnn ) are automatically generated when the DS is created.



The ID Nr Together with the SEND or RECEIVE, NET and opposite NODE information is the unique address for the Dataset. It is therefore permitted to have the same ID Nr defined multiple times in one Node (refer to X366HAttachment 5X).

If more than 2 DSs are transmitted between the same Nodes the SCAN_FTR must be different to prevent delays in transmission (refer to DS in Database Element reference manual).

For the Node to Node communications, the following defaults are used:

SORTREF = NO The 1PstP DAT of a DS must be an IL.

(Note: Bits 1 to 22 of the 1Pst P IL will be used to transmit the error signals of the REALs 1 to 22.)

The 2PndP DAT is normally IL also but can be used for REALs if required. The remaining DATs are normally R but can be used for ILs if required. SCAN_FTR has to be the same for sender and receiver. Normally set to 1.

In order to reduce the re-engineering effort due to inconsistent Send and Receive DS parameters, it is highly recommended to use the Normal configuration at all times.

2 @ IL (max 31x2 binary inputs) Send Data: CONV-BI (IL,5,31), Receive Data: CONV-IB (IL,4,31)

22 @ R (max of 22 analogue values)

3.6.4 DAT for DS (AC450)

Communication between PC programs in different nodes are made with DAT elements which are packed in dataset (DS) and transferred via the Master bus. Naming of DAT is SSRRIDD.ILn or SSRRIDD.Rnn where : SS: number of the sending node, for example 16 for WSC RR: number of the receiving node, for example 17 for ST ID: Ident number, for example 02 D: S for Send, R for Receive. IL: Integer Long, R is for Real number and n, nn is a running number.

3.6.5 Analogue and Binary signals transferred between PC programs (AC450)

Use AOC and DOC DB-Elements for signal-transfer between PC programs in the same Node. If value should not be accessible from the OS then set the PROC_SECtion value to -1.



3.7 DSP Data Transfer between AC160 and AC450 Data Set Peripheral (DSP) is used for Data Transfer via AF100 between AC160 stations and AC450 and between AC160 cpus in different AC160 stations. General naming template: e.g. CLP301

CL P3 01

As with DS, the associated DATs ( .ILnn, Rnn, .Bnn ) are automatically generated when the DSP is created: The ID Nr is the unique address for the Data Transfer TOGETHER with the SEND/RECEIVE and STATION. DSPs which send/receive signals to/from type circuits do not carry normal process signals.

3.7.1 Signals Transferred from AC160 to AC450

In AC160 KKS is (normally) without the equipment unit code (i.e. the 1 PstP 2 numbers of actual KKS

3.7.2 DSPs for Process signals

Generally for the Station to Station communications, the following defaults are used: 1 @ IL (max of 31 Binary inputs) Send Data: CONV-BI (IL,5,31) Receive Data: CONV-IB (IL,4,31) 7 @ R (max of 7 Analogue values) This ratio is free to change as required, however a minimum of 1 IL must be defined per DSP.

The first 7 bits of the first IL will be used to transmit the error signals of the REALs 1 to 7. A maximum of different 50 DSP Idents can be defined in each Processor Module* but a

maximum of 200 DSPs per processor module* and per physical AF100 bus are supported (250 DSPs from Firmware version 2.1/x).

The Station Number used by DSPs is virtual, it does not have to be the same as the RSTA1/RSTA2 Station number defined in the PM6xx, so a physical station can be subdivided into several virtual stations to increase the number of DSPs (i.e from 50 up to 200 or 250 that can be sent/received from from a single controller module on 1 AF100 bus).

A maximum of 2 AF100s (4 AF100s from AC160 Firmware version 2.1/x) can be connected per physical station

Refer to section TX367H3.7.4368HTypical Definition of DSPs



3.7.3 AC160 Station Numbering

Generally a Turbo Group will consist of 4 to 6 processors in 3 stations:

GT ST Controller Description 10 11 P1 Protection channel 1 (& IP/LP Bypass Stop valves if applicable) 10 11 C1 or CL Closed Loop 10 C2 Closed Loop 2 (for GT24/26 only) 20 21 P2 Protection channel 2 (& LP Stop Valves) 20 OL Open Loop (for GT only) 30 31 P3 Protection channel 3 (& IP/LP Bypass Control valve if applicable)

3.7.4 Typical Definition of DSPs

Due to the quantity of drives used and the limitation of 50 DSP Idents per processor module it has been necessary to use Virtual Station Nrs instead of actual station Nrs in defining the DSPs. A maximum of 200 DSPs (250 from Firmware version 2.1/x) can be Sent/Received over one physical AF100 bus. This allows an average of 5 (6) DSPs per virtual station to virtual station connection. The main reason for the high quantity of DSPs is due to the data transmission between Operator Station (HMI) and the drives in AC160. The DSP format for these HMI DSPs is also different from those for Process signal exchange to DCS. For these reasons 2 separate destinations (HMI and DCS) have been defined.

Source Ident. Virt. Stat.

DCS 0 01 .. 07 P1 1 10 .. 17 P2 2 20 .. 27 P3 3 30 .. 37 HSI 4 40 .. 47 OL 5 50 .. 57 C1 6 60 .. 67 C2 7 70 .. 76

Note: 1st digit identifies the Source-Ident Nr of DSP Source, 2nd digit identifies the Source-Ident Nr of the Destination. i.e. OL is defined as 5, CL as 6 therefore virtual station Nr used for DSP transmission from OL to CL is 56, from CL to OL is 65

3.7.5 DSPs used in Broadcast mode:

Although AF100 is used as a point to point communications bus the AF100 can be used in broadcast mode. We do not use broadcast mode directly. We use a multiple Point to Point method. If a broadcast is required, a single DAT source is sent via several Point to Point DSPs. DATs with this usage are named differently to other DATs used for single Point to Point DSP communication but are sent over DSPs using the standard Point to Point naming convention General naming template: e.g. OLPXB01

PX . OL PX B 01

Example: The following single DAT might be broadcast.to multiple destinations via multiple DSPs.

DAT Type: DAT Ident: Via DSP Ident: From: To:

DAT(B) OLPXB01 OLP101 OL P1 DAT(B) OLPXB01 OLP301 OL P3

3.7.6 EVS Data transfer between AC160 stations and AC450

Event Set (EVS) elements are used only for transport of time-tagged events from DIC or DIS database elements in AC160 to AC450. For DI boards the sequence of events parameter must be activated. An EventSet element groups a set of Event Channels for sending (AC160) or receiving (AC450) events. Events from DIC signals must be transferred in separate EVSs from those used for DIS signals. A maximum of 32 EVS can be sent from each AC160 CPU (or pair of CPUs) over a single physical AF100. General naming template: e.g. EHWCL01

E HW/SW E HW CL 01 E SW CL 01

Where: HW is used for transmitting signals from Hardware inputs (DIS) SW is used for transmitting signals from Software generated signals (DIC)

3.7.7 MDATs (AC160)

For Data transfer between processors in the same BIOB MDATs are used. Unlike other Advant elements, MDATs are referenced by their Number not their name.The MDAT Names may be duplicated but MDAT Numbers must be unique.The MDAT Nrs must be the same in both processor databases. MDATs have the same name as the source signal but without the signal extension: e.g: An MDAT(R) would be named: MAC10CP001 if it had MAC10CP001_XQ60 as its source.



3.7.8 High Speed Link: HSL (AC160)

For High Speed Data transfer between AC160 stations HSLs are used. HSLs are connected between CPUs. If High speed Links are used It is not possible to connect them to Redundant CPUs as the redundant CPUs use the HSL for synchronising their Data/status. For this reason they are only used between the Protection CPUs P1, P2 and P3. The Database elements used for this communicating are HSLS (send) and HSLR (Receive). General naming template: e.g. [P1IL01]

[ ] [ P1 IL 01 ]

Typical DB Configration: Protection Channel 1:

Element Name Type Channel Ident

HSLR [P2IL01] IL 1 2 HSLR [P2R01] R 1 2 HSLR [P3IL01] IL 2 3 HSLR [P3R01] R 2 3 HSLS [P1IL01] IL n.a. 1 HSLS [P1R01] R n.a. 1

4. Basic Configuration of DCS All PC program PCPGMs are expected to have the same time setting (40ms) therefore the execution order of the PC programs will be deterministic if loaded into the controller in order of PC number

4.1 AC450 PC Program Structure Error! Objects cannot be created from editing field codes.

Note: PC1..3 is used for input signals handling (Redundant channels). Due to limitations on Local Data Area, If a large number of inputs exist in any of these PC programs (.AAX file larger than approx 300kb) it may be necessary to split it up (use PC4)

4.3 Correction Functions (AC450) Correction functions of individual analogue inputs may be implemented in PC1 to 3 (dependant on the redundancy) or in PC4 to 6 (which are recommended for containing the hardware I/O analogue limits logic). If PC1 to 3 is used then CONTRM numbers higher than 32 must be used for these correction functions as CONTRM 1..32 are reserved for the analogue input card signals. In order for PC program 1 to 3 to be updated at any time by in-house tools, the signal exchange between Supervision output signal (XQ60) and correction input MUST be made via the Database not via internal connection or Name. 1oo2, 2oo3 or AVERAGE values of analogue input signals are implemented in PC4.

4.4 Typical PC structure In AC450 Contents are divided per PC-program according to process function . A limit of approximately 20..25 drives or Large functions in each PC-program will avoid reaching the limit of the Local Data Table. Note that analogue f(x) Curves use up a large amount of Local Data Area. Having a structure is more important than attempting to force a particular structure for all projects. The PC element numbers used below are an example only but should be followed unless there is a compelling reason why they are not feasible for a particular application. The actual PC element numbers used can be determined on a per project or even per node basis.

PCx x.1 CONTRM (for General Input Logic) x.11 CONTRM (for 1PstP FunctionGroup) x.11.1 FUNCM (Application logic FunctionGroup) x.11.2 FUNCM (Application logic SEL) x.11.11 FUNCM x.11.11.1 through n MOVES (Inputs to TC) x.11.11.50 TC FG x.11.11.m through 20 MOVES (Outputs from TC) x.11.12 x.11.12.1 through n MOVES (Inputs to TC) x.11.12.50 TC SEL x.11.12.m through 20 MOVES (Outputs from TC) x.21 CONTRM (for 1PST P Drive) x.21.1 FUNCM (Application logic for Drive) x.21.11 FUNCM x.21.11.1 through n MOVES (Inputs to TC) x.21.11.50 TC DRIVE x.21.11.m through 20 MOVES (Outputs from TC) x.22 CONTRM (for 2nd Drive) x.51 CONTRM (for 1PstP Analogue drive) x.51.1 x.51.11 PIDCONA x.51.11.21 GENUSD (for visualisation) x.52 CONTRM (for 2nd Analogue drive) x.91 CONTRM (for Outputs/General Output Logic)

Note: To make sure any TC can be exchanged properly by a new version at any time (see 1AHL105876, Exchanging Type Circuits Design Directive) it is essential that the PC element number of the TC is higher than the highest number used by the Logic PC elements, e.g. as shown here above .50.

4.6.13 Analogue Input Calculated (AIC on AC450):

PC Programs WRITE to :CALC_VAL, PC Programs READ from VALUE AICs can be written from the HSI if the signal source is connected to :CALC_VAL and the Database Update is Blocked (same as AI) Database settings refer to AIS, section X373HAnalogue Inputs AIS (e.g. AIS810):X.

4.6.14 Digital Input Calculated (DIC on AC450):

PC Programs WRITE to :CALC_VAL PC Programs READ from :VALUE DICs can be written from the HSI if the signal source is connected to :CALC_VAL and the Database Update is Blocked (same as DI) DICs can be given VALUE TREATMENT (Alarm List, Event List) Set ERR_TR =2

Note: in AC160 the SCANTIME setting of DICs has a huge affect on system load. If a single DIC is set to a fast scantime, then the EVENTSET task runs at this speed also. As an example: a scantime of 640ms instead of 80ms can reduce the cpu load by approx. 20% (on a PM645) depending on the quantity of EVS's used.

4.6.15 Analogue Output Calculated (AOC):

PC Programs and HSI: READ and WRITE to VALUE In AUTO the value is written from the PC program, in MAN the value can be changed by the Operator Station. AOCs do NOT have any Value Treatment. Set ERR_TR =0 (Err_Tr terminal has no effect)

4.6.16 Digital Output Calculated (DOC):

PC Programs and HSI READ and WRITE to VALUE In AUTO the value is written from the PC program, in MAN the value can be changed by the Operator Station. DOCs have NO value Treatment. Set ERR_TR =0 (Err_Tr terminal has no effect)

Note: setting and comment are also valid for DOS



4.7 AC450 Hard- and Software Limits

4.7.1 S800-Stations

In a normal configuration up to 12 Stations can be used on one AF100-bus. Be aware that if you use more than 9 stations, the INSCANT has to be redused! Always use the defined scantimes in section TX374H4.6.1 X: X375HAF100 scantime settings for S800X.T On one Station a maximum of 12 I/O-Modules can be connected, 24 modules if there is a bus-extension installed. If you want to do a non-standard configuration with more than 12 S800-stations, use the busload-calculation excel-sheets to verify your configuration. There is no limitation in the number of stations, but you have to adjust the scantimes to have the bus-load below 70%.

5. Hardware Supervision

5.1 Transmitter and Wire-break Supervision in AC450 Refer to X376HTAttachment 7: AC450 Transmitter and Wire-Break SupervisionTX for PC Program printout

Note: This does not apply to RTD (pt100) or TC input connection unit signals AI830 (S100: DSTA146, DSTA155).

The Advant standard for supervising differential channel analogue inputs is part of the AI810 (for S100: DSTA133/135) firmware and gives an alarm when a signal falls 2,4% below the RANGE_MIN value of the signal range (equivalent to 3.62mA). This can only be considered as wire break supervision for the Rosemount transmitters which fail to various signal levels above this (eg: 3.75mA. depending on the model). A similar situation can occur at the top end of the transmitter range if the transmitter is set for upscale burnout. For supervising transmitter failure, the PTUP standard value of 1.25% of Meas. Range below 4mA (equivalent to 3.8mA) and 5.625% above 20mA (equivalent to 20.9mA) is required, a software solution must therefore be implemented. For each Analogue input-card a separate CONTRM will be used (numbered according to AI card number). The CONTRM will head 16 FUNCMs (numbered according to the AI Channel numbers). Each FUNCTM will contain a program which supervises the signal received from the Analogue Input card. It sets the :ERR pin (disturbance bit) of an AIC in the database if the signal falls below the 3.8mA limit, or rises above the 20.9mA limit or if the Analogue Input Card is DISTURBED. At the same time all the AIC Limits are DISABLED. The disturbed signal is allocated the signal name extension _XQ63. The Analogue signal used by the DCS will be the AIC signal, and will be identified by the signal name extension _XQ60. To avoid inconsistencies between AIS and AIC ranges etc, the program writes the following signals from the AIS Database Element to the AIC: RANGE_MIN to DISPMIN RANGE_MAX to DISPMAX LIM_L1 to LIM_L1 LIM_L2 to LIM_L2 LIM_H1 to LIM_H1 LIM_H2 to LIM_H2 HYS to HYS All changes to measurement ranges, Limits and Hysterisis must be made on the AIS database Element or in a PC program which writes to the AIS. (PC4) If the AIS supervision has not detected an error, the program writes the following signals from the AIS Database Element to the AIC to enable the alarms: EN_L1 EN_L2 EN_H1 EN_H2

Notes: 1) Any previously exceeded limit output of the AIC remains set to 1.

2) If it is required that limit signals which were already active before the disturbance are switched off (similar to Procontrol method) then the XQ63 signal should be used to block unwanted limit signals in the destination PC program or in the PC program where the limits are generated (eg. PC 7..9) In this case, the AIC limits displayed on the HSI can have a different status to the DIC alarm.

3) If the Limit status should stay as it was before the disturbance, then the XQ63 interlock is not required.



5.2 Analogue Signal Transfer Between Nodes (AC160,AC450) In applications where Analogue Values are transferred between Nodes, supervision of Signal failure must be implemented. Signal Failure (No Updating of the Receiving Database Element) will occur if :

Node-Node communication is lost. (no connection for more than the number of cycles stated below) - for sending Node type: AC450 3x CYCLETIM; - for sending Node AC160 (DSP) 8x CYCLTIM when REDUNDANT CI522's are used i.e. AC450AC160)

Input signal Error: Process input signal error bit :ERR of the AIS or AIC database element is set or the process input signal is less than the transmitter supervision limit.

Note: Refer to X377HTAttachment 6: AC450 Node to Node Analogue Signal Error Handling TX for AC450 to AC450 communication.

Refer to X378HTAttachment 1: Analogue Signal Error Handling AC450 to AC160 TX for AC450 to AC160 communication

Refer to X379HTAttachment 2: Analogue Signal Error Handling AC160 to AC450 TX for AC160 to AC450 communication

5.3 Transmitter and Wire-break Supervision in AC160

5.3.1 Wire-break Supervision for S600 (e.g. AI625)

For supervising transmitter failure, the same values as required in AC450 cards 3.8mA and 20.9mA is required. In order to carry this out, a software solution is therefore being implemented.

The input LO_LIM2 of the Analogue Input channel (AIS) is set to 1.25 The input HI_LIM2 of the Analogue Input channel (AIS) is set to 105.625 Set Hysterisis to 0.1

The output VALUE



5.4 Multiple measured Analogue process variables (Drift alarm) If the same analogue process variable is measured multiple times for use in control or protection logic, then the drift (difference) between these signals must be supervised and alarmed if it exceeds a defined limit (the standard limit is 10% of measuring range. If a different value is required, this must be specified in the PFuP). This supervision is to be performed even if not specifically defined in the PFuPs. For implementation refer to X384HTAttachment 13: 2oo3 Analogue signal and alarm handlingTX.

5.5 Error-Handling of signals used for Protection This section relates to Alstom requirements. Requirements for other customers may differ. Refer to X385HTAttachment 14 TX through X386HTAttachment 21 TX for detailed methods. Fault Categories defined by Alstom:

Damage caused by a fault Fault Category (FC) Extent of injury or damage Energy

set free Persons Plant Downtime* Timing of event Event FC

very high highly likely severe >6 months immediate major accident 1 high less likely extensive months almost immediate accident 2 low not likely medium weeks moderately delayed fault 3 none none slight days easy to control disturbance 4

* = time to repair

Switching options and required Error-Handling for protection logic:

Protection Method

Action if 1 signal is disturbed

Action if multiple signals are disturbed

comments

2oo3 Active 0 (FailSafe)

Alarm 2oo3 Err ==> Trip Refer to Notes 1 & 2 1 chan. disturbed + 1 chan. Trip = Trip Output

2oo3 Active 1 Alarm 2oo3 Err ==> Trip Refer to Notes 1 & 2 1 chan. disturbed + 1 chan. Trip = Trip Output

1oo2 Active 1 Alarm 2oo2 Err ==> Trip Refer to Notes 1 & 2 1 chan. disturbed + 1 chan. Trip = NO Trip Output

2oo2 Active 1 Alarm No Action Not used for FC1 and FC2 1oo1 Active 1 Alarm Not Applicable 1oo1 Active 0 (FailSafe)

Trip Not Applicable Only rarely used when defined by the Process Engineer as the availability is highly reduced.


Trip (Already Tripped)

Only rarely used when defined by the Process Engineer as the availability is highly reduced.


* * *Do not use as 2oo2 with Active 1 covers this.

Notes: 1) General: The use of error signals in the trip logic is a requirement for FC1 and FC2 protection only

2) For reasons of consistancy, the 2oo3 and 1oo2 trip logic methods (with error signals) used for FC1 and FC2 will be used for all Fault category protection levels where 2oo3 and 1oo2 methods are implemented.

Basically every measurement error is alarmed either via the measurement or via the card disturbance, therefore no additional engineering is required for alarming of the individual signal errors. These switching options with their error-handling are valid for protection logic and are to be used for both analogue and for binary logic.



6. Tips and Tricks for AC450 planning

6.1 MANSTN Text entered in the Database element E1_NAME is displayed on the object display. The PC Element :OUTPUT must be connected to the database Element input :POUT for correct visualisation. The inputs PO_MIN & PO_MAX as well as MIN & MAX and OUTP_HL and OUTP_LL should be used to ensure the correct output of the MANSTN. Inputs to either MAN or E1 are converted to PULSES inside the macro!!! Any constant signals will block EXTERNAL switching!! For Manual Stations which are ALWAYS in MANUAL MODE but which have ONLY SUPERVISOR ACCESS, the MANSTN HSI Object is specified as Dialog = NONE then the Supervisor has access to the Manual Station Output ONLY via the Engineering Station (modify database element OUTPUT pin).

6.2 PIDCONA The limits from the OS only function when the PC Element pin EOLIM (Enable Outside Limits) is set to 0. When External Limits are enabled there is no indication to the Operator and changing the limit from the screen HAS NO EFFECT on the Output!!! The AOS/AOC Output connected to the PIDCONA/MANSTN Output must have its limits set 0 to 100% to ensure correct HSI representation. If Measured Value or Deviation Alarms are not required the PC Element pin ALCBLK must be set to 1. Default settings for Controller parameters: (These rule of thumb values must be optimised during the plant startup):
