Changing Processor Modes
15–5
REMote Run Mode (All Processors)
The REMote Run mode allows you to:
• Monitor the ladder program, rung state, and data as it is being executed.
• Save a processor file to disk.
• Use the search function.
• Force inputs and set up outputs.
• Monitor and edit data files.
• Perform SLC 5/03 and SLC 5/04 online edits.
• Change a mode using a programmer.
While you are in the REM Run mode, the processor scans or executes the ladder
program, monitors input devices, ener gizes output devices, and acts on enabled I/O
forces.
When the processor is in this mode it functions as if the keyswitch were in the RUN
position. Online program editing is allowed in this mode.
RUN Mode (SLC 5/03 and SLC 5/04 Processors)
When the keyswitch is in the RUN position, you can only change the mode by
changing the keyswitch position. Y
ou cannot use a programming device to remove
the processor from the Run mode. When the 5/03 keyswitch is in the RUN position,
online editing and processor mode changes via Channels 0 and 1 are not permitted.
PROGRAM Mode (SLC 5/03 and SLC 5/04 Processors)
When the keyswitch is in either the RUN or PROG mode, you cannot use APS to
take the processor out of the specified mode. Y ou must change the keyswitch
position to change the processor ’ s mode.
When the SLC 5/03 and SLC 5/04 processor’ s keyswitch is in the REMote position,
the processor remains in the mode it is currently in. W ith the keyswitch in this
position you can change between REMote Program, REMote T est, and REMote Run
using your programming device. Refer to status file S:2/4 and 2/18 in the
Instruction Set Refer ence Manual. You can also toggle the mode from
REMote-PROGram-REMote or REMote-RUN-REMote using the keyswitch.
