Unit/Protocol Compatibility
Note 1. The Peripheral Bus Mode is used for Programming Devices excluding Pro-
gramming Consoles. If Programming Console is to be used, set pin 4 of the
DIP switch on the front panel of the Unit to OFF so that the communica-
tions settings are automatically detected instead of using those specified
in the PLC Setup.
2. Supported for CPU Units with unit version 3.0 or later and Serial Commu-
nications Boards/Units with unit version 1.2 or later only. For CPU Units,
however, only automatic CompoWay/F connection is possible.
