Redundancy of the KOM process - instance processes.

The KOM process can also be started in instance (shadow) mode - then several KOM processes are connected to one D2000 Server as instances (no. 1, 2 ... upto 15) of the same KOM process (e.g. [1]_REMOTE.KOM , [2]_REMOTE.KOM - see start parameter /W). One instance is active (communicating), the others are passive.
Note: in the case of server protocols (e.g. IEC 870-5-104 Server), the KOM process can also be used in active-active mode (two/more KOM processes are active).

For more information, see the Redundancy of communication chapter.
