System Operation and Configuration Chapter 4
that the E300 output relays can go to a temporary state (Open, Closed, or Hold
Last State) when a communication fault occurs. Configure this temporary state
by using the Communication Fault Mode parameters.
If communication between the E300 relay and a network scanner or control
system is not restored within the Fault Mode Output State Duration time
(Parameter 561), the E300 output relays go to a final fault state (Open or
Closed), which you configure by using the Final Fault Mode parameters.
If communication between the E300 relay and a network scanner or control
system is restored within the Fault Mode Output State Duration time (Parameter
561), the E300 output relays resume with the state commanded by the network
scanner or control system.
The parameters that are listed on the following pages configure the
Configuration Fault Mode for each E300 output relay.
Fault Mode Output State Duration (Parameter 561)
Fault Mode Output State Duration (Parameter 561) is available in E300 relay
firmware v5.000 and higher. This parameter defines the amount of time in
seconds that the E300 relay remains in the Communication Fault Mode state
when a communication fault occurs. A value of (0) represents forever.
If communication between the E300 relay and a network scanner or control
system is not restored within the Fault Mode Output State Duration time the
E300 output relays go to the final fault state, which you configure by using the
Final Fault Mode parameters.

Output Relay 0 Communication Fault Action (Parameter 306)
Output Relay 0 Communication Fault Action (Parameter 306) defines how
Output Relay 0 responds when a communication fault occurs when this
parameter is assigned as a Normal/General Purpose Relay or Control/Control &
Trip R el a y.
