On the processor there is a Key switch with
RUN REM PROGRAM

I know you have to have the key switched to Program in order to download a new .rss file, but what is the difference between RUN and REM?
I know REM stands for REMote, and I think that the program will run in either RUN or REM

I looked through the PDF's on This Page
I can't seem to find the answer.
Thank-you
George Bradley
 
RUN Position
This position places the processor in the Run mode. The processor
scans/executes the ladder program, monitors input devices, energizes
output devices, and acts on enabled I/O forces. You can only change
the processor mode by changing the keyswitch position. You cannot
perform online program editing.
To change the processor mode to Run, toggle the keyswitch from
PROG or REM to RUN. When the keyswitch is left in the RUN
position, you cannot use a programmer/operator interface device to
change the processor mode.

PROG Position
This position places the processor in the Program mode. The
processor does not scan/execute the ladder program, and the
controller outputs are de-energized. You can perform online program
editing. You can only change the processor mode by changing the
keyswitch position.
To change the processor mode to Program, toggle the keyswitch from
REM or RUN to PROG. When the keyswitch is left in the PROG
position, you cannot use a programmer/operator interface device to
change the processor mode.

REM Position
This position places the processor in the Remote mode: either the
REMote Run, REMote Program, or REMote Test mode. You can change
the processor mode by changing the keyswitch position or by
changing the mode from a programmer/operator interface device. You
can perform online program editing in this position.
To change the processor mode to REM, toggle the keyswitch from
RUN or PROG to REM. When the keyswitch is in the REM position, you
can use a programmer/operator interface device to change the
processor mode.
 
So I can leave the Key in REM and then change the processor from Program to Run with the RSLogix software from my LapTop.
I'll try that Monday Thanks Ron
 
yeah... i can't think of a single machine in our plant that we don't leave on REM for easy access, except a cardboard baler that we've never had a need to get into.
 
George. To add to the correct info Ron gave you--be aware that if you are editing a program you can do it with the key in REM, but if the key is in REM and you Download a program the software will cause an electronic shift from REM to PROGRAM, causing the processor to stop running the program. You won't have to physically turn the key. RSLogix will ask you whether you want to do this before it actually does it.

We leave our processors in the REM position as well.
