GE IC695CPE310-ABAB is the core main control CPU module of PACSystems RX3i control system. It is embedded installed in the RX3i standard rack, occupying dual-slot space. After accessing rack backplane power supply and high-speed bus, it automatically completes hardware self-test, kernel initialization, storage unit verification, communication port matching and bus synchronization upon power-on, and enters the system main control operation state after normal initialization.
During normal system operation, as the operation and scheduling core of the entire industrial control system, this module collects on-site working condition data of all I/O modules and intelligent functional modules in the rack in real time through the high-speed backplane bus. After high-speed kernel operation, logic judgment, interlock verification and closed-loop algorithm processing, it outputs accurate control instructions to drive on-site execution equipment to complete automatic control actions.
