Logical names are used to override default values in the log_names.cfg file for the CIMPLICITY Base System and options.

 Note: Do not confuse logical names with environment variables. Logical names are found in the log_names.cfg file, while environment variables are accessed through the Control Panel.

The following device communications have logical names that can be modified:

	Native device communications (except OPC) supporting unsolicited data.
	Allen-Bradley Communications
	Mitsubishi TCP/IP Communications.
	SNP Communications.
