CPU module key switch description

RUN running mode and REM remote mode

Run the CPU, the user cannot be stopped by software; cannot modify the program, including a full download and online download, not mandatory, cpu modules plc programming software can not write variables (HMI can write variables); can not be reset, cold reduction and empty application.

From the "run" or "PRG mode dial to" REM "mode, CPU working mode to maintain the state, users can through software running or stopping CPU;  digital output plc can modify the program online, can force, you can also write variables can be reset, cold reduction and empty applications.
