Available Modes of Operation
The following section describes the available modes of operation for the SLC 500
processors and MicroLogix 1000 controllers.
SLC 5/01 and SLC 5/02 Processors and MicroLogix 1000 Controllers
Remote mode indicates that the processor can be changed via the communication
channels. Since these processors do not have a keyswitch, all modes are considered
to be remote. The following table summarizes the status of the processors while in
the remote mode.

SLC 5/03 and SLC 5/04 Processors
The SLC 5/03 and SLC 5/04 processors have a 3-position keyswitch on the front
panel of the module. The keyswitch allows you to select one of three modes of
operation:
• RUN
• PROGram
• REMOTE program/test/run
The r esponse time of changing the keyswitch from RUN to either REMote or
PROGram can be up to 2.5 seconds (depending on the size of your user
program). Do not use the keyswitch in place of a hard-wired master control
relay or an emergency stop switch.
