Architecture Engineering FAQ

Q1: Is the HIEE300890R0001 UAC383AE01 PCB compatible with all AC800M controller variants, and does it require any firmware updates upon installation?
The UAC383AE01 PCB is designed for use within the AC800M controller family, including PM891, PM865, and PM864 processor modules. In most cases, the PCB is a direct replacement component that does not require independent firmware configuration — firmware is managed at the controller module level via ABB Control Builder M software. However, it is recommended to verify the hardware revision of the host controller against ABB’s compatibility matrix prior to installation, particularly in systems running older firmware baselines. Our technical team can assist with revision verification upon request.

Q2: Can this PCB be replaced during live system operation in a redundant AC800M architecture, and what is the recommended maintenance procedure?
In AC800M systems configured with redundant processor modules (dual PM891 hot-standby), controller-level maintenance — including PCB replacement — can typically be performed with the redundant controller assuming active control, minimizing process disruption. The specific procedure requires a controlled switchover initiated through System 800xA or Control Builder M, followed by physical replacement of the PCB in the passive controller, and a subsequent synchronization and validation sequence before returning the system to full redundancy. It is strongly recommended to follow ABB’s documented maintenance procedures and to perform this operation during a planned maintenance window. The 12-Month Warranty covers the replacement unit from the date of dispatch.
