String Configuration

IO.Ethernet.IPSelect

 

Indicates the active IP address. Possible values are the following:

·0: The main IP address is selected

·1: The alternative (backup) IP address is selected

 

If the Ethernet (or RAS) Interface is connected, this Tag indicates which of the two IP addresses configured is in use. If the Interface is disconnected, this Tag indicates which IP address is used first on the next connection attempt.

During the connection process, if the active IP address is not available, the I/O Interface tries to connect using the other IP address. If the connection with the alternative IP address works, this one is configured as the active IP address (automatic switchover).

To force a manual switchover, write the value 1 (one) or 0 (zero) to this Tag. This forces a reconnection with the specified IP address (0: Main IP address or 1: Alternative IP address) if the Driver is currently connected. If the Driver is disconnected, this Tag configures the active IP address for the next connection attempt.
