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 execution of the user program and processes diagnostic interrupt OB 82.
You can call SFC 51 or 59 in OB82 in the user program to view detailed diagnostic data
output by the module.
Diagnostics data remain consistent until the program exits OB 82. 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.
