                                                      Overview

                                                      IC695CPE305 is a mid-range central processing unit for Emerson PACSystems RX3i PLC platform (formerly GE Fanuc). As the core controller of the whole automation system, it executes user control logic, coordinates all I/O modules, and processes multi-channel communication data. It adopts dual-bus backplane compatibility design, supporting both new PCI high-speed modules and legacy Series 90-30 I/O cards, suitable for medium-scale process and machinery control projects.

                                                         Runs interlock, PID regulation, sequence control and motor protection programs to realize automatic field equipment control.
                                                      2. Dual-bus I/O scheduling
                                                          
                                                         Communicates with analog/digital I/O modules through PCI and serial backplane simultaneously, collecting field sensor signals and outputting control commands.
                                                      3. Multi-protocol communication gateway
