Product Description
The Allen-Bradley 1203-GU6 Enhanced DeviceNet communication module bridges SCANport-enabled devices with a DeviceNet network. It translates DeviceNet messages into SCANport language for use by supported devices like AC drives, motion control systems, and motor protectors. The module features SCANport (8-pin mini-DIN) and DeviceNet (5 or 10-pin) ports, mounts on a DIN rail, and requires 24VDC power. Measuring 1.8" x 3.0" x 5.0", it needs clearance for airflow and wiring. It supports Change of State (COS) for efficient data updates. Installation, configuration, and repair should be performed by qualified SCANport technicians only, after disconnecting power. DIP switches configure operation settings, with factory defaults including node address 63 and 125K DeviceNet data rate. Ensure proper DIP switch settings for machine safety. Operating temperature is 32-122F with 0-95% non-condensing humidity, and it requires a NEMA Type 1 or IP 30 enclosure.
Is Your Device Showing These Signs?
The Allen Bradley 1203-GU6 frequently exhibits communication failures stemming from corrupted firmware or damaged communication ports, requiring firmware reflashing or port replacement. Power supply issues are common, leading to intermittent operation or complete failure, necessitating power supply repair or replacement. I/O module failures manifest as unresponsive inputs or outputs, demanding module repair or replacement. Resolving grounding problems and noise interference is essential for stable operation, achieved through proper grounding techniques and noise filtering. Finally, addressing configuration errors ensures proper system functionality, requiring parameter verification and correction within the PLC program.
Technical specifications
The Allen-Bradley 1203-GU6 is an Enhanced DeviceNet communication module that connects SCANport-enabled devices to a DeviceNet network.
