Hardware Specifications

Industrial Control and Firmware Compatibility

The 2711P-K4M20D8 uses an integrated Ethernet interface together with RS-232 and USB ports for external device communication. The supplied data does not identify a specific Ethernet protocol or deterministic network class, so protocol performance must be evaluated against the connected controller and application configuration.

Firmware flash compatibility is dependent on the PanelView Plus 6 terminal firmware and installed runtime environment. Firmware files should be matched to the exact terminal catalog number and applicable software revision before an upgrade or replacement operation. The supplied data does not specify a firmware revision for this unit.

The terminal provides 256 MB RAM and approximately 512 MB of nonvolatile memory, with approximately 79 MB identified as free user memory in the supplied specifications.

Frequently Asked Questions (FAQ)

Q: What DC supply range is specified for the 2711P-K4M20D8?

A: The supplied specifications identify an input voltage range of 18-32 VDC and an input power range of 18-30 VDC. The actual installation supply should remain within the applicable manufacturer limits.

Q: What physical operator input is provided?

A: The terminal uses a keypad with 8 function keys, designated F1 through F8. The supplied keypad specification is 1 million presses.

Q: Does the terminal provide Ethernet and RS-232 communication simultaneously?

A: The catalog configuration identifies Ethernet and RS-232 as integrated communication interfaces, with two USB peripheral ports also provided.

Field Installation Guidelines

• Verify the catalog number 2711P-K4M20D8 before installation because PanelView Plus 6 variants differ in display, communication, input, and power configurations.
• Confirm that the external DC supply is within the specified input voltage range before energizing the terminal.
• Route DC power wiring separately from high-voltage switching conductors and high-current motor wiring where practical.
• Keep communication wiring away from sources of electromagnetic interference and avoid unnecessary parallel routing with power conductors.
• Terminate cable shields according to the applicable control-system grounding design and plant electrical standards.
• Verify Ethernet and RS-232 pin assignments and cable type before connecting external equipment.
• Do not apply USB peripheral connections until the connected device has been confirmed compatible with the terminal operating environment.
• Provide adequate panel clearance for connector access and cable bend radius.
• Do not substitute a different PanelView Plus catalog variant solely on the basis of physical display size; communication, power, and input configurations must also match.
• The supplied data contains conflicting weight values, with 1.31 lb (0.60 kg) in the detailed specification table and 1.06 lb in the additional notes. Verify the physical unit or applicable manufacturer documentation before using weight for mechanical design.
