LAB,name: Loading a user system into the target automation subsystem which has logged on. The diskettes are entered via the mini floppy disk drive connected to the configuration automation subsystem. Loading is only possible after the system has been set to “STO” mode.

LAB; Continuation instruction if more than one diskette is used. Loading is only possible after the system has been set to “STO” mode.

LAB:@RS; Aborting the loading process, terminating bus configuration and restarting the target subsystem. The target subsystem memory iscleared.

ARB,name; Filing the user system of the target automation subsystem, which has been logged on, onto diskettes inserted in the mini floppy disk drive connected to the configuration subsystem. The target subsystem memory is cleared.

ARB; Continuation instruction if more than one diskette is used.

ARB:@RS; Abortion of the filing process.

LABR; Loading the user RAM area of the configuration subsystem into thelogged on target AS. The previous configuration of the target subsystem is cleared and replaced by the new data – as in direct loading. Loading is only possible after the system has been set to “STO” mode.

ARBR; Filing the user RAM area of the logged on target subsystem into the RAM of the configuration subsystem. When sending this instruction the configuration subsystem must have sufficient free RAM area to accept the system from the target subsystem. After the data has been transferred completely, the old system in the configuration subsystem is deleted by a restart and the user subsystem, loaded from the target subsystem, is activated. The RAM of the configuration subsystem must first be cleared if there is not sufficient free RAM to accept the target subsystem configuration.

considered as acknowledgement. The first mark after “BR” is managed by the system. The user

GA.ORPA: Analog parameters

GB.ORPA: Binary parameters

FB.ORPA: Output inhibit for function blocks via PBT.Cf. “Operator inputs via the PBT” (Chapter 10.1.2).

FC.ORPA: Special character set for printers; only effective if GB.ORPA GB 223 = 1 in GB.ORPA.See “NEDA” for entering special characters (Chapter 10.7.2).

FSA.ORPA: Extension of GA.ORPA

Interface lists: see Appendix (Chapters 10.7.7 to 10.7.8).

10.6 Troubleshooting

Remedial actions for various faults; malfunctions.

Parameterization/operator input: input isnot rejected, but not accepted by theblock.

Check whether check bit (C) has been set in theparameter concerned. If it has, check whether theCHECK block modifies the value entered.

Malfunction Remedial action

Cycle overflow

Picture selection from operator positionnot possible (loop display, GP, BR).Lists (B;) and parameterization displaysare output.

Log is not displayed

Error message is not displayed butfault is still present.

A block is not processed.

Link not ready

No operator input possible; no output onecho line.

GP block: Block cannot be cleared

Remove blocks or insert XB blocks with graduatedscanning parameters.

Picture inhibit for this operator position has beenactivated in GB.ORPA → Set GB to “0”.

Incorrect device setting (”GE,k,l;”)

Message has been acknowledged (”QM;”), butnot cleared (”QF;”).

Has a block been installed?Is there a preceding XB, XA or S block which isOFF?Has STOP mode been selected? (remedial action:”STA;”)

Interface not ready? (”TPER;”)GA.ORPA.28 = –1 (transmitter inhibit)

PBT has not been connected:Enter ”;” and switch off SHIFT mode on keyboard.PBT connected, PBT keys have not been labelled:enter ”BR;” via PBT to label keys. Check KEYS-WITCH.

Delete entries (NRPL = 0 for operator–controlla-ble blocks making entries).

Linking blocks

Block cannot be removed

Block cannot be defined

Individual block types are not displayedon the PBT (after ”BR;”)

Individual characters are printed incorrectly

Receiver has not logged off.Log off receiver.

Incorrect cycle or no cycle has been selected →select correct cycle.

Illegal name

Check FB.ORPA; the parameter = type no. or typeno. + 256 must be 1 to enable type to be displayedon the PBT.

Check FC.ORPA if the character coding enteredthere is used (only if GB 223 = 1 in GB.ORPA).

Configuration instructions are not accep-ted.

Check authorization level.

Group code for check call:

If the group code has been set, the CHECK block is also called up when a block is being defined,output interconnected or deleted.

EL,C; Setting the group code for general activation of the CHECK routine.

EL,N; Resetting the group code

Separating element:

The separating element separates internal from external parameters (no outputs). Internal parame-ters are then only output under “NEDA”.

EL,no,$$$$;

no: Consecutive number of the separating element.

Parameterization of FC.ORPA (printer conversion field):

Starting at .FC(16), FC.ORPA contains 256 special characters. If normal parameterization of theseelements cannot be achieved (the keyboard has no special characters), their decimal equivalentsmay be entered (cf. symbol table).

The block is selected under “NEDA”:

A,FC,ORPA;

Parameterization of one or more elements:

ELL,FC:index,dec1,dec2,...;

dec1, dec2,...: Decimal equivalents of the characters.

The characters are shown in .FCI as decimal equivalents and in .FC as symbols (of the VDU, notthe printer).
