Module Replacement

To replace modules and update firmware in a redundancy system, you can use these methods:
  • Method 1—Modules are replaced and firmware is updated while the redundancy system is powered up and the controllers are in RUN mode. To use this method, refer to the procedures in the appendix.
  • Method 2—Modules are replaced while the redundancy system is powered down and the controllers are not in RUN mode. To use this method, perform the same steps as during initial setup. See Set Up a Redundancy System.
