Configure Counter State in Communication Fault Mode
You can configure the counter to specific states when a connection fault occurs, that is,
the connection between the controller and the module breaks.
Counter Behavior Immediately After a Connection Fault
When the connection between a controller and module breaks, the counter can behave in
the following ways, depending on how the Counter State in Fault Mode parameter is
configured:
- Continue counting – Default
- Hold its last state
- Transition to a user-defined value
You can choose to reset the stored count value when the module when is in
Communication Fault Mode.
The counter remains at that state value until the connection to the controller is
re-established.
When Communication Fails in Program Mode
When communication fails in Program Mode, the counter can behave in the following
ways, depending on how you configure the When Communication Fails in Program Mode
parameter:
- Leave counter in Program Mode state – It causes the counter to behave as defined by the Counter State in Program Mode selection.
- Change counter to Communication Fault state – It causes the counter to behave as defined by the Counter State in Communication Fault Mode selection.
