Working Principle The module establishes high-speed synchronization link between primary and standby C200 processor. It continuously reads real-time control data, calculated process values and internal register status from primary processor, then transmits and writes all data into standby processor memory. Diagnostic circuit monitors operating status of both processors in real time. Once primary processor has hardware failure, communication loss or power abnormality, the module triggers switchover. Standby processor takes over all control tasks immediately, and sends redundancy switchover event alarm to DCS system.
Installation Requirements Wear anti-static wrist strap during disassembly and assembly; Insert the card into designated rack slot and lock fixing screw tightly; Install matched redundancy cable between two C200 processors; Complete cabinet protective grounding and verify grounding quality; Confirm hardware version matches C200 controller firmware; Set redundancy configuration parameters in Experion engineering station after installation.
Precautions for Use Do not plug or unplug the module under power-on state; Keep redundancy cable separated from high-power power cables; Regularly check panel LED synchronization indicator status; Do not use unmatched hardware revision for redundant processor pair; Execute redundancy function test after module replacement.
