3.10 Switching between Remote (REM) and Local
(LCL)
The following operating procedure describes an example of switching from Local (LCL) to
remote (REM).
Switching between REM and LCL is possible for only controllers with remote input feature.
● Local:
Performs control using target setpoints set in the controller.
● Remote:
Performs control using external analog signals as target setpoints.

Note: The PID group number when the controller is in remote-mode operation is the same as the number set in the Target
Setpoint Number (SPNO) parameter.
NOTE
If remote status is achieved by external contact input (contact input is ON), switching
between REM and LCL cannot be achieved by keystroke.
