A controller in this fault state can be recovered by downloading a new project or an offline copy of the project to the controller. Rockwell Automation recommends users set the controller switch to RUN mode to prevent remote programming. Users are encouraged to have a backup copy of the project in the case it is necessary to recover from an event. Rockwell Automation also recommends users should consider migrating to the Micro870 controller.
