You can use the Motion Direct Command (MDC) feature to initiate motion
while the controller is in Program mode, independent of application code that is
executed in Run mode. These commands let you perform a variety of functions,
for example, move an axis, jog an axis, or home an axis. See the Logix5000™
Motion Controllers Instructions Reference Manual, publication
RM002 for more information.
A typical use might involve a machine integrator testing different parts of the
motion system while the machine is being commissioned, or a maintenance
engineer, under certain restricted scenarios in accordance with safe machine
operating procedures, wanting to move an axis (like a conveyor) to clear a jam
before resuming normal operation.
ATTENTION: To avoid personal injury or damage to equipment, follow these
rules regarding Run mode and Program mode.
• Only authorized, trained personnel with knowledge of safe machine operation
should be allowed to use Motion Direct Commands.
• Additional supervisory methods, like removing the controller key switch,
should be used to maintain the safety integrity of the system after returning
the safety controller to RUN mode.
