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. For more information, see the Redundancy of communicationCommunication chapter. |
Communication objects are configured in the D2000 Cnf tool.

Finally, the I/O tags are configured - the parent of the I/O tag is the communication station. The type must be defined for the I/O tag (input/output type digital/analog/integer/absolute time/relative time value). Filters, conversion to technical units, process alarms, and other parameters can be configured at the measured pointthe I/O tag.
On the I/O tag, it is also possible to configure the status text (converting a number to a text constant for the display) and the transformation palette (which determines the standard format during display, unless it is changed by a format mask).
