Backplane Bus Communication & Deterministic Network Interfacing
The Allen-Bradley 2711-T5A9L1 PanelView 550 terminal communicates over RS-232 serial channels utilizing DH-485 protocol to exchange deterministic tag data, alarm bits, and user inputs directly with SLC 500, MicroLogix, and ControlLogix systems. The primary serial interface maintains reliable point-to-point and multi-drop communication velocity, while an independent RS-232 serial printer port handles asynchronous alarm printing and diagnostic record logging. Onboard firmware flash compatibility supports rapid project file transfers via PanelBuilder32 software, maintaining high I/O density scaling and predictable scan updates across industrial machine control environments.
Frequently Asked Questions
Q: What power input range is required to operate the 2711-T5A9L1 terminal?
A: The 2711-T5A9L1 requires a nominal 24 VDC external supply, operating reliably within an allowable input range of 18 VDC to 32 VDC.
Q: Can the 2711-T5A9L1 operator interface be swapped while 24 VDC power is live?
A: No. Main DC supply voltage and serial communication cables must be completely de-energized prior to terminal insertion or removal to prevent electrical arcing and logic corruption.
Q: How are operator screen layouts and configured tags retained during a panel power loss?
A: System runtime configurations, display objects, and application logic are written directly to internal nonvolatile flash memory, securing all screen data without requiring battery maintenance.
Field Installation Guidelines
Cut a rectangular opening measuring 123 mm x 156 mm (4.86 in. x 6.15 in.) in a NEMA 4X or IP65 enclosure door. Position the 2711-T5A9L1 through the panel cutout, ensuring the rubber sealing gasket sits flush against the panel surface to ensure watertight ingress protection.
Secure the housing using the provided mounting clamps, tightening the screws evenly in an alternating sequence to a torque of 1.1 Nm to 1.4 Nm (10 in-lbs to 12 in-lbs). Wire the 24 VDC input leads using copper conductors rated for 75 deg C or higher, observing correct terminal polarity (+24 VDC and DC Common). Bond the terminal grounding stud directly to the main cabinet ground bus with a low-impedance copper conductor.
