• Serial Ports: 2× RS-232, 1× RS-485 (for HMI, programming, or Modbus devices).

• Network: R-Net (proprietary industrial network) for inter-rack communication.

• Status LEDs: Power, Run, Fault, Comm (communication).

Core Functions

• Executes ladder logic, BASIC, and control block programs for automation tasks.

• Coordinates distributed I/O across multiple racks in DCS systems.

• Communicates with other AutoMax processors, HMIs, and third-party devices via R-Net/Modbus.

• Logs system faults and events for diagnostics.

• Supports remote programming and monitoring via serial/network ports.

Application Scenarios

• Legacy Industrial Automation: Replacement control module for aging AutoMax DCS/PLC systems in manufacturing, power, and process industries.

• Process Control: Used in paper mills, steel plants, chemical processing, and material handling systems.

• Retrofit & Maintenance: Cost-effective repair for older production lines where full system replacement is uneconomical.

Operation & Maintenance Instructions

• Safety: Disconnect all power and discharge capacitors before handling.

• Installation: Align with rack slots, seat edge connectors firmly, secure mounting screws.

• Configuration: Load user programs via programming tool; set network addresses and I/O mappings.

• Maintenance: Keep board clean/dry; inspect connectors quarterly for corrosion; replace backup battery every 3–5 years.

• Troubleshooting: Check LED status for faults; verify backplane power and communication cables; reflash firmware if corrupted.
