Core Functions

• Execute ladder‑logic, function‑block programs with watchdog safety supervision.
• Support PID loop control, high‑speed counter, interrupt subroutine and floating‑point arithmetic.
• Dual‑port Ethernet enables daisy‑chain networking, HMI connection, peer‑to‑peer PLC data exchange.
• Built‑in station‑manager console for IP address setup and basic diagnostics.
• Comprehensive system diagnostics, fault logging; battery‑backed RAM preserves program and real‑time clock during power loss.

Installation Requirements

• Mount into dedicated CPU slot of Series 90‑30 main baseplate.
• Confirm rack power‑supply provides sufficient 5 VDC current for CPU and other modules.
• Install IC693ACC302 lithium backup‑battery module for memory retention at power‑off.
• Operate within 0‑60℃ ambient, avoid heavy dust, vibration and condensation.
• Complete hardware configuration before downloading user application program.
• Configure Ethernet IP via Proficy Machine Edition or RJ‑11 station‑manager port.

Common Fault Modes

1. CPU fault LED illuminated: watchdog timeout, program error, memory parity fault, configuration mismatch.
2. Unable to enter RUN mode: program missing, hardware config mismatch, key‑switch set to STOP.
3. Ethernet communication failure: cable defect, incorrect IP/subnet setting, protocol parameter mismatch.
4. Program & register data lost after power‑cycle: backup‑battery low voltage or defective.
5. Real‑time clock failure: backup‑battery exhausted, battery replacement required.
6. Cannot access station‑manager console: wrong cable type, incorrect serial communication parameters.
