PanelView Plus Communication & Backplane Bus Integration
The 2711P-RN3 attaches to small-logic operator interface terminals to facilitate multi-node DH-485 serial communication. Operating across distances up to 30 meters, the interface board establishes real-time register mapping without impacting terminal display rendering or backplane bus communication velocity across internal processing channels. Integrated diagnostic LED indicators provide local status monitoring during active network transmission.
Frequently Asked Questions
Q: Does the 2711P-RN3 support hot-swapping while the PanelView Plus terminal is powered?
A: No. Power to the PanelView Plus terminal must be removed before inserting or extracting the 2711P-RN3 communication module to prevent interface circuit damage.
Q: What is the maximum recommended transmission distance for the DH-485 interface on this module?
A: The specification limits the DH-485 connection cable length for this module to 30 meters.
Field Installation Guidelines
Disconnect all operating power sources from the PanelView Plus terminal before beginning installation.
Maintain standard electrostatic discharge (ESD) precautions by utilizing a grounded anti-static wrist strap.
Remove the expansion module cover plate on the rear of the PanelView Plus 400 or 600 terminal.
Align the 2711P-RN3 module connector with the terminal backplane socket and press firmly until fully seated.
Secure the retaining screws, connect the DH-485 network cable within the 30-meter limit, and verify terminal communications upon power-up.
