Communication function settings
Commands and frequency settings are given priority by communication. (Prioritized by commands from the
panel or terminal block.) Thus, command and frequency settings from communication are activated,
regardless of the command mode selection () or frequency settings mode selection settings ().
However, setting 48: SCLC (switching from communication to local) with input terminal function selection and
when inputting from an external device, it is possible to operate at command mode selection () and
frequency setting mode selection () settings.
Moreover, connecting the optional extension panel and selecting local mode with the LOC/REM key changes
to panel frequency/panel operation mode.
