Core Functions

• Execute ladder logic, function‑block programs with watchdog safety monitoring.
• Support PID control, high‑speed counter, timer‑counter and shift‑register functions.
• Serial communication for HMI, programming terminals and slave devices.
• Built‑in system diagnostics, fault logging, memory parity error detection.
• Battery‑backed RAM for program and data retention during power loss.

Installation Requirements

• Insert into CPU slot of Series 90‑30 main baseplate.
• Match rack power supply current rating to CPU consumption.
• Install backup lithium‑battery module IC693ACC302 for memory retention.
• Keep ambient temperature 0‑60℃, avoid heavy dust, vibration and condensation.
• Complete hardware configuration before downloading user logic program.

Common Fault Modes

1. CPU fault LED lit: watchdog timeout, program error, memory parity failure.
2. Cannot go to RUN mode: program missing, hardware configuration mismatch, key‑switch set to STOP.
3. Communication failure: serial port wiring error, incorrect SNP/SNPX parameter setting.
4. Data loss after power‑off: backup battery voltage low or defective.
5. RTC clock stops: backup battery failure, requiring battery replacement.
