Configuring Redundancy

The Plant SCADA driver supports multiple I/O server / device redundancy.

The driver represents each OPC UA server as a separate I/O device. In a normal operating state, the driver will communicate to the server via the primary I/O device. If the connection to the server via the primary I/O device is lost, the server will be communicated via a standby I/O device which is connected to the server and has the next highest priority if multiple redundant I/O devices are configured.
