Reset Button
You can reset the controllers
or the safety partner
with the reset button. The reset button is only read during a power-up or restart. If you press the reset button at another time, it has no effect.For a safety-enabled controller, the Safety Locked status or safety signature does not prevent you from performing a controller reset. Because the application is cleared from the controller during a reset, the safety level of the controller is cleared also. When you download a safety project to the controller, the safety level is set to the level specified in the project.
A controller has two stages of reset:
- A Stage 1 reset clears the application program and memory but retains the IP address and all network settings. A stage 1 reset occurs only if the controller contains a user application.
- A Stage 2 reset returns the controller to factory 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 version.
The Safety Partner reset returns the safety partner to out-of-box settings, including firmware.
IMPORTANT:
Because port enable/disable status is associated with the application program, the controller Ethernet ports become enabled after a Stage 1 or Stage 2 reset.
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.
