Device redundancy

The OI Server Manager provides the ability to assign redundant device for fail-over protection in the event of device failure. Two devices must be configured in the same Communication Driver having identical item syntax.

Primary and secondary devices will be set up in the REDUNDANT_DEVICE object in the OCMC, along with a common item name (ping item) shared by each device to determine device status.

Note: Unsolicited message configuration is not supported from the device redundant hierarchy.
