Allen-Bradley 2711-B6C2 Human Machine Interface

Allen-Bradley 2711-B6C2 is a PanelView Standard 600-terminal that provides a compact stand‑alone operator interface for Allen‑Bradley PLCs on serial networks. It includes a DH-485 communication port (9-pin D-shell), enabling data exchange with compatible controllers over the DH-485 fieldbus. This 2711-B6C2 variant is part of the older PanelView 600 line and has been discontinued by the manufacturer, with surplus and refurbished units commonly found through distributors. Typical deployments include local machine control and status monitoring on small-to-medium automation lines, where operators view and input data at the panel and PLCs respond to inputs via the DH-485 network. Because it is a legacy device, many users plan migrations to newer PanelView Plus hardware for longer-term support, while customers may still operate existing PV‑600 installations.
