Backplane Bus Communication and Network Integration
The 2711-T9C9 interfaces with host programmable logic controllers via its integrated RS-232 port utilizing the DH-485 communication protocol. High backplane bus communication velocity and deterministic message handling allow real-time register mapping to SLC 500, MicroLogix, and ControlLogix controllers. Point-to-point and token-passing DH-485 networking ensure continuous synchronization of process variables, alarm state updates, and user input commands while maintaining firmware flash compatibility across legacy Rockwell Automation systems.
Frequently Asked Questions
Q: What is the maximum distance supported for the RS-232 DH-485 interface without external converters?
A: Standard point-to-point RS-232 connections are rated for a maximum cable distance of 15 meters (50 feet). Extended distances require a 1761-NET-AIC Advanced Interface Converter to transition to RS-485 differential signals.
Q: Can the application firmware and terminal runtime applications be updated via the onboard communication ports?
A: Yes. Firmware flash updates and PanelBuilder32 application transfers can be executed through the primary RS-232 DH-485 port using a direct serial connection or via a PCMCIA memory card inserted into the rear expansion slot.
Q: Does the 2711-T9C9 require an external DC power supply?
A: No. The 2711-T9C9 features an internal universal AC power supply that operates directly on 100 to 240 VAC line voltage at 50/60 Hz.
Field Installation Guidelines
- Panel Cutout Preparation: Cut the panel enclosure opening to the specified dimensions, removing all burrs and debris to ensure a uniform seating surface for the perimeter sealing gasket.
- Gasket Verification: Ensure the environmental sealing gasket is fully intact and correctly positioned in the bezel channel before inserting the terminal into the cutout to maintain NEMA/IP ingress protection ratings.
- Mounting Clamp Fastening: Insert the terminal into the cutout and secure it using the provided mounting clamps. Tighten the clamp screws evenly in an alternating sequence to a torque of 1.1 to 1.4 Nm (10 to 12 in-lb). Do not overtighten, as this can deform the front bezel.
- Earthing and Wiring: Connect a 14 AWG (2.5 mm sq) protective earth ground wire from the terminal ground lug directly to the main cabinet ground bus. Wire the AC line power to the screw terminals on the power block with power disconnected.
