Diagnostic interrupt
When diagnostic interrupts are enabled, incoming error events (initial occurrence) and
outgoing error events (error is cleared) are reported by means of interrupt.
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 obtain detailed diagnostics data
from the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostic interrupt when the program exits OB82.
Load restrictions in horizontal mounting position
In horizontal mounting position, the module loads must be restricted so that two adjacent
inputs or outputs do not exceed their rated load.
Load restrictions in vertical mounting position
In vertical mounting position, the module loads must be restricted so that four adjacent inputs
or outputs do not exceed their rated load.
