IMPORTANT: You must uninstall any existing versions of the Redundancy Module Configuration Tool (RMCT) before you install version 8.5.1.0 of the RMCT. If you do not uninstall the previous versions, you can have difficulty if you try to uninstall version 8.5.1.0 later.

You can use 1756-RM2 or 1756-RM2XT redundancy modules to commission a redundant system. You can commission a system without any additional programming. However, there is additional functionality available if you use the modules with the RMCT.

When a redundancy module is at firmware version 20.030 and an attempt is made to flash to 20.010, the module reverts to 20.022.0.

A workaround to recover from this is to flash the module in the following order: 20.030 -> 20.009 -> 20.010.
