PLC-5 Communication Interface Characteristics
The 1771-KE module provides serial communication processing between PLC-5 controllers and external devices through Data Highway and RS-232-C ports. The module operates as an interface component within the 1771 I/O chassis, transferring communication data through the PLC backplane.
The Allen-Bradley PLC-5 architecture uses backplane communication for module data exchange. The 1771-KE supports Data Highway network connectivity and RS-232-C serial communication, allowing connection with compatible external communication equipment.
Frequently Asked Questions
Q: What communication interfaces are available on the 1771-KE module?
A: The module provides Data Highway and RS-232-C communication ports for PLC-5 system communication functions.
Q: What is the backplane current requirement of the 1771-KE?
A: The module requires 750 mA backplane current and operates from the PLC-5 chassis 5 VDC supply.
Q: Does the 1771-KE require an external power supply?
A: No external power supply is specified. The module receives operating power through the PLC-5 backplane.
Field Installation Guidelines
Install the 1771-KE module in a compatible Allen-Bradley 1771 I/O chassis slot with backplane power removed during insertion or removal. Verify rack power capacity before installation to maintain the required backplane current availability.
Connect Data Highway and RS-232-C communication wiring according to the applicable PLC-5 system wiring requirements. Route communication cables separately from high-voltage power conductors to reduce electrical interference. Maintain proper cable shielding and connect shields according to the control system grounding practice.
Confirm communication parameters, including serial interface settings, before placing the module into service. Inspect connectors and wiring arms for proper mechanical engagement during installation.
