Special cases for 4DIO/4DO
Error diagnostics
The two diagnostic events "short-circuit to M (DI)" (triggered by short-circuit of the encoder
supply) and "short-circuit to M (DO)" (triggered by short-circuit of the output) are displayed in
an "Error" diagnostic alarm.
Diagnostics: Short-circuit to M (DI)
If this parameter is enabled, the system generates an "Error" diagnostics when it detects a
short-circuit of the outputs to ground.
Diagnostics: Short-circuit to M (DO)
If this parameter is enabled, the system generates an "Error" diagnostics when it detects a
short-circuit of the encoder supply to ground.
