Backplane Bus Communication & Deterministic Network Interfacing
The Allen-Bradley 2711-B6C9L1 PanelView 600 terminal communicates over RS-232 serial channels utilizing DH-485 protocol to exchange deterministic tag data, alarm bits, and user setpoints directly with SLC 500, MicroLogix, and ControlLogix systems. The primary serial interface maintains predictable point-to-point and multi-drop communication velocity, while an independent RS-232 printer port handles asynchronous alarm event logging and report printing. Onboard firmware flash compatibility supports rapid application project downloads via PanelBuilder32 software, maintaining reliable I/O density scaling and scan synchronization across industrial automation environments.
Frequently Asked Questions
Q: What power input range is required to operate the 2711-B6C9L1 operator terminal?
A: The 2711-B6C9L1 requires a 24 VDC nominal external supply, operating reliably within an input voltage window of 18 VDC to 32 VDC.
Q: Can the 2711-B6C9L1 terminal be removed or reinstalled while 24 VDC power is energized?
A: No. Main 24 VDC power feeds and RS-232 communication cables must be completely isolated before disconnecting or installing the terminal to avoid electrical contact arcing and logic corruption.
Q: How are operator screen layouts and configured system parameters retained during a power loss?
A: System application graphics, tag maps, and user settings are written directly to internal nonvolatile flash memory, securing application files indefinitely without requiring a battery.
Field Installation Guidelines
Cut a rectangular mounting opening measuring 167 mm x 264 mm (6.57 in. x 10.39 in.) in a NEMA 4X or IP65 enclosure door. Position the 2711-B6C9L1 through the panel cutout, ensuring the sealing gasket rests flush against the panel face to maintain environmental sealing.
Secure the terminal housing using the provided mounting clips, tightening the screws evenly in an alternating sequence to a torque specification of 1.1 Nm to 1.4 Nm (10 in-lbs to 12 in-lbs). Terminate the 24 VDC power leads using copper wire rated for 75 deg C or higher, observing correct terminal polarity (+24 VDC and DC Common). Bond the terminal grounding stud directly to the cabinet main earth grounding bus with a low-impedance copper strap.
