Controller Modes
The table below shows the possible controller modes when the mode switch
positions at PROGRAM, REMOTE, or RUN. For example, if the Mode Switch
is at RUN and you want to test a control program with running it for a single
scan, you have to first change mode switch position to REMOTE before you run
the control program in the remote test single scan mode with your RSLogix
500/RSLogix Micro programming software.
Changing Mode Switch Position
Mode Switch position can be changed at two different times using LCD keypad.
One is when the controller is powered up, and the other is while the controller is
powered on.
Mode Switch position can be set to either PROG or RUN when the controller is
powered up. This allows the controller operation which is different from the
previous mode, that is, any program under RUN before can be stopped or any
new program can be run when the controller is powered up.
• How to forcibly set Mode Switch to RUN when the controller is powered
up:
Press OK key for 5 seconds when the controller is powered up. The
following LCD screen appears if it’s successfully done.
