Main Functions

1. Execute ladder logic, function block, structured‑text user program; hardware floating‑point arithmetic, periodic interrupt subroutine processing.
2. Dual‑port integrated Ethernet switch, realize PLC programming download, HMI connection, EGD inter‑PLC data exchange, Modbus‑TCP third‑party device communication, support network daisy‑chain wiring, save network switch hardware.
3. Manage backplane bus, realize data exchange with local I/O, special‑function modules and multi‑expansion racks.
4. System‑level fault diagnosis: power failure, program error, I/O fault, watchdog overtime; store fault log; support EZ‑Store offline program download without PC.
5. LED status indication on front panel:   ‑ Green RUN：CPU run mode indicator   ‑ Red FAULT：CPU hardware / program fault alarm   ‑ Green OK：Power‑on and self‑test pass indicator   ‑ LAN1 / LAN2：Ethernet link / activity indicator

Installation & Wiring Requirements

1. Cut off full PLC rack power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling CPU module.
2. Insert IC693CPU374 into dedicated CPU slot on main baseplate and lock latch; check power‑supply backup‑battery condition.
3. If using expansion racks, connect official GE expansion cable between main‑base and expansion‑base 25‑pin D‑sub port.
4. Use industrial shielded Ethernet cable for network wiring; separate network cables from high‑power cables; complete protective grounding according to GE Series‑90‑30 hardware manual specification.
5. After replacement：power‑on PLC, verify RUN / OK / FAULT / LAN LED status; set IP address, download hardware configuration & user program; perform full local & expansion‑rack I/O test and Ethernet communication test.
6. Replacement note: Verify project firmware compatibility; confirm battery health; full‑system commissioning test mandatory before unit put‑into‑service.
