2.12.13 FC 5: GP_DIAG Basic program, diagnostic alarm, and module failure
Description of Functions
Module defects and module failures are detected in this section of the basic program.
The FC5 block parameter can be used to define whether the PLC is to be placed in STOP
mode. The PLC is placed in STOP mode only for incoming events. Exceptions of the
parameter "PLC-Stop" are the Profibus-MCPs parameterized at FB 1 (must be connected to
the DP1 Bus).
Declaration
FUNCTION FC 5: VOID
VAR_INPUT
PlcStop: BOOL:= TRUE;
END_VAR
Call example
As far as timing is concerned, the basic program can be executed after other user programs.
This is advisable since the FC5 circuitry will place the PLC in Stop mode.
This example contains the standard declarations for OB 82 and OB 86 and the call of the
basic program block.
