• Remote RUN/STOP : Section 6.12.1

• Remote RESET : Section 6.12.2

6.12.1 Remote RUN/STOP

The remote RUN/STOP performs RUN/STOP of the CPU module externally with the

CPU module RUN/STOP/RESET switch at RUN.

(2) Applications of remote RUN/STOP

Using remote RUN/STOP for the following remote operations are useful:

• When the CPU module is at a position out of reach

• When performing RUN/STOP of the control board CPU module externally

(3) Calculations during Remote RUN/STOP
