Evidence-backed product details

Rebuilt from individual evidence

Classic Automation identifies 2711C-T3M/B as an Allen-Bradley PanelView C300 monochrome touchscreen terminal and lists RS-232 DH-485, RS-232 DF1, RS485, and DC power.

Rockwell Automation identifies 2711C-T3M as a PanelView Component C300 touchscreen HMI used to monitor and control devices attached to a controller.

The terminal intervenes as the operator-facing HMI between a human user and the attached controller, carrying display/input interactions over the documented communication paths.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: This PanelView C300 terminal is the operator interface between a person and the attached controller in a machine-control system. It displays process information and accepts touch input through the documented serial/controller communication paths; the exact /B variant compatibility remains unknown.
System position: This PanelView C300 terminal is the operator interface between a person and the attached controller in a machine-control system. It displays process information and accepts touch input through the documented serial/controller communication paths; the exact /B variant compatibility remains unknown.
Upstream / inputs: This PanelView C300 terminal is the operator interface between a person and the attached controller in a machine-control system. It displays process information and accepts touch input through the documented serial/controller communication paths; the exact /B variant compatibility remains unknown.
Downstream / outputs: This PanelView C300 terminal is the operator interface between a person and the attached controller in a machine-control system. It displays process information and accepts touch input through the documented serial/controller communication paths; the exact /B variant compatibility remains unknown.
Limitations: Unknown: exact /B variant - The Rockwell manual identifies 2711C-T3M without documenting the /B suffix difference.
