* There are two kinds of functions: function of responding to signals from the device specified with
the EOQF parameter, and function of responding to singles from the terminal board only.
External input signal Function
Input terminal function 12 (PNL/TB: OFF) Operation panel operation EOQF =1
Input terminal function 12 (PNL/TB: ON) Terminal board operation
* When the highest-priority command is entered from an external control device or a terminal block,
it takes priority over commands from the device specified with the EOQF parameter.
