(2) Communication and Expansion

Communication protocols: TCP/IP, Modbus RTU, Modbus TCP, CANopen, DeviceNet

Scalability: Supports 7 expansion racks, copper cable transmission for 30m, fiber optic transmission for 2km (multimode)

Remote access: Supports PLC/DCS access via Modbus TCP, supports USB/Ethernet local configuration

(3) Safety and Compliance

Safety features: IOLOCK fault safety (output power loss), requirement for independent overspeed protection device, ESD protection

Environmental compliance: ATEX Zone 2 (explosion-proof), Class I Division 2 (hazardous area)

Electromagnetic compatibility: Complies with EN 61000 and needs to be installed in a metal cabinet


Software and Configuration

Development environment: Woodward GAP (graphical programming) Ladder Logic， Support rate group scheduling (minimum 5ms)

Configuration tools: AppManager (firmware upgrade, network configuration, fault monitoring), ToolKit (visual debugging)

Diagnostic functions: module LED fault codes, real-time status monitoring, historical fault records, remote diagnosis


Installation and maintenance

Installation requirements: The chassis should be installed vertically, with 8cm of heat dissipation space reserved above and below, and shielded cables should be grounded

Module replacement: Supports hot swapping (CPU/Remote RTN module needs to be reset first)

Maintenance cycle: The module undergoes health checks every 6 years, with an increased frequency of checks every 20 years or more
