3.29.4 SM 322; DO 8 x DC 24 V/0.5 A - Interrupts
Introduction
The SM 322; DO 8 x DC 24 V/0.5 A can trigger diagnostic interrupts.
For detailed information on the OBs and SFCs mentioned below, refer to the
STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if parameters are not set
accordingly. Program the interrupt enable parameter in
STEP 7.
Diagnostics interrupt
Incoming error events (initial occurrence) and outgoing error events (error is cleared) are
reported by means of diagnostics interrupt, if this interrupt is enabled.
The CPU interrupts user program execution in order to process diagnostics interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to view detailed diagnostics data
output by the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostics interrupt when the program exits OB82.
