Controller Reset Button
You can reset the controller with the reset button behind the front door on the
controller. You press the button in and hold it during a controller power-up
sequence to reset the controller.
Table 11
describes the differences between the reset stages.

WARNING:
When you press the reset button while power is on, an Electric
Arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.

Stage 1
A Stage 1 reset clears the application program and memory, but
retains the IP address and all object attributes designated as
non-volatile.
A Stage 1 reset occurs only if the controller contains a user
application.
Supported
Supported
Stage 2
A Stage 2 reset returns the controller to out-of box settings, including
firmware, and clears all network settings.
A Stage 2 reset occurs only if the controller does not contain a user
application, and the current controller firmware is not a 1.x revision.

IMPORTANT
Remember the following:
• Because port enable/disable status is associated with the application
program, ports become enabled after a Stage 1 reset.
• A reset occurs only when you hold the button while the module powers
up. If you press the reset button during runtime, there is no effect.
