Call example
As far as the time is concerned, the basic program must be executed before other interrupt-driven user
programs. It is, therefore, called first in OB 40.
The following example contains the standard declarations for OB 40 and the call for the basic program.
13.13.13 FC 5: GP_DIAG Basic program, diagnostic alarm, and module failure
Function
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).
