What could be the recommended setting of Hold Up Time for M580 Distributed Equipment.

The hold up time represents the time that device outputs are maintained in their current states after a communication disruption and before taking their fallback values. Because distributed devices are not connected to the primary CPU during a switch-over, set the hold up time to a value greater than the expected duration of the communication interruption.

For Modbus TCP devices:
Set the hold up time to exceed: 4.4 x (MAST period) + 600 ms.

For EtherNet/IP devices:
Set the hold up time to exceed: 4.4 x (MAST period) + 5000 ms.
