Replace Communication Modules with a New Series

You can replace
EtherNet/IP™
 communication modules with a new series without updating controller firmware by using these methods:
  • Synchronization and switchover—Use this method if electronic keying is not set to Exact Match.
  • Redundancy System Update (RSU)—Use this method if electronic keying is set to Exact Match. You must configure the new modules to use Exact Match. See Online Firmware Updates.
IMPORTANT:
  • Before you replace modules, make sure that you have the correct firmware for all new modules.
  • When you replace modules, you must do so in pairs or the system cannot synchronize after a switchover.
  • Partnered pairs of
    EtherNet/IP™
     modules must use the same values for the following parameters for IP address swapping to work: IP addresses, network mask, gateway address
