EtherNet/IP and PLC-5 Communication Interface Characteristics
The 1771-AF1 performs optical conversion between fiber channels and DH+/RIO communication interfaces. The module supports two DH+/RIO ports and two fiber-optic ports for extending communication distances beyond standard copper network limitations. Communication signal integrity is maintained through optical transmission paths, reducing susceptibility to electrical noise coupling in industrial environments.
The module integrates with PLC-5 system architectures through defined communication protocols and operates with external 5 VDC power. The stand-alone enclosure design allows installation independently from the main I/O chassis while maintaining compatibility with PLC-5 communication infrastructure.
Frequently Asked Questions
Q: What communication protocols are supported by the Allen-Bradley 1771-AF1?
A: The 1771-AF1 supports Data Highway Plus (DH+) and Remote I/O (RIO) communication protocols through its converter interfaces.
Q: What is the power requirement of the 1771-AF1 module?
A: The module requires a 5 VDC power supply with an input current of 600 mA. The specified power dissipation is 5 W.
Q: Can the 1771-AF1 be installed inside a 1771 I/O chassis?
A: The module is specified as a stand-alone unit installed through mounting slots. It is not a standard plug-in I/O module, although it interfaces with PLC-5 communication systems.
Field Installation Guidelines
Install the 1771-AF1 in a controlled industrial enclosure environment according to the specified NEMA Type 12 enclosure requirements. Mount the converter using the provided mounting slots and maintain sufficient clearance for cable routing and service access.
Use the specified DH+/RIO communication cables and fiber-optic connections according to network installation practices. Separate communication wiring from high-voltage power conductors and high-current switching equipment to reduce electromagnetic interference.
Terminate cable shields according to the plant grounding standard. Avoid sharp bends or excessive mechanical stress on fiber-optic cables during installation. Verify power polarity and 5 VDC supply stability before connecting communication interfaces.
