Configuration
Slave number and baud rate (communication speed) must be set for both the ports.
These settings must correspond with the settings in the used PC-program. For the rear
port it is possible to set permission of changes between active setting groups, ActGr-
pRestrict, and the setting restrictions, SettingRestrict, as well.

Use this menu to set slave number and baud rate when to communicate on the IEC 870–
5–103 communications bus, also known as 6FKQLWWVWHOOH  or VDEW 6. The IEC bus
