Effect of PLC Modes and Actions on EGD Operations
The table below indicates what happens to the configuration and operation of EGD when in
different PLC modes and when certain PLC actions take place.
For example, the normal PLC mode for EGD operation is RUN with Outputs enabled. In this
PLC mode, EGD remains configured and exchanges are both produced and consumed. If the
PLC mode is set to STOP with I/O disabled, the Producer ID remains configured, but production
and consumption stop.
When configuration is lost, the EGD configuration must be stored again.
