Function Libraries 4.4.9 Installing a Reference Value IRQ Module The count of Ventura Remote PLC's counter reaching the reference value generates an interrupt request (IRQ) which can interrupt the processing of the current program and run an IRQ module instead. This requires that running an interrupt module (IRQmod) following reference value interrupt is admitted by the project parameter settings made using the PLC Configuration Editor. To install a program module as a reference value IRQ module you must run the following code to identify the module: Index := INDEXOF (module name); Afterwards, run the following function in order to set up the error module: REGIT_T3IRQ ( Index ); After successful completion, the function returns TRUE. FUNCTION REGIT_T3IRQ: BOOL VAR_INPUT POU_ID: WORD; END_VAR VAR END_VAR 88 E 700 GB
4.4.10 Setting up the Watchdog Function Libraries Every task can have a watchdog (timer-controlled monitor) to it. Function "SET_WATCHDOG" can be used for both setting the watchdog timeout and enabling/disabling watchdog execution.
