Product Overview
The Allen-Bradley 2711-B5A1 is a PanelView 550 operator terminal used as a Human-Machine Interface (HMI) in industrial automation systems. It provides operators with a local interface to monitor machine status, adjust parameters, and interact with PLC-controlled processes.
This model is part of the PanelView Standard (PV550) series, widely used in older Rockwell Automation systems.

Function and Working Principle
The 2711-B5A1 acts as a front-end interface between operators and PLC systems. It operates by:
- Displaying real-time machine/process data from PLC
- Sending operator inputs (touch or keypad) back to the controller
- Executing locally stored HMI application screens
- Supporting basic alarms, status messages, and control functions
It typically runs applications created in PanelBuilder32 software.
Role in Industrial Systems
This PanelView terminal is used to:
- Provide machine visualization and control
- Allow operator interaction with PLC systems
- Display alarms, faults, and process status
- Enable basic configuration of industrial equipment
It is common in older automation systems still in operation today.
Industrial Applications
- Conveyor systems
- Packaging machinery
- Material handling equipment
- Pump and motor control systems
- Legacy manufacturing automation lines
Installation Notes
- Panel-mounted installation in control cabinet doors
- Requires AC power input (wide-range supply supported)
- Communication setup depends on PLC network (often RIO or DF1/RS-232 systems)
- Programming requires legacy PanelBuilder32 environment
Compatible Equipment
- Allen-Bradley SLC 500 PLC systems
- PLC-5 systems (via Remote I/O)
- MicroLogix systems (via serial communication)
- Legacy Rockwell industrial controllers
Key Advantages
- Simple and reliable operator interface
- Rugged design for industrial environments
- Supports both keypad and touchscreen input
- Proven long-term field reliability
- Easy integration with legacy PLC systems
Limitations
- Obsolete / legacy product (PanelView Standard series)
- Limited graphics and memory compared to modern HMIs
- Serial/RIO communication only (no Ethernet)
- Requires outdated configuration software (PanelBuilder32)
Replacement / Modern Alternatives
| Model | Type | Application |
|---|---|---|
| PanelView Plus 7 | Modern HMI | Ethernet-based upgrade |
| PanelView 800 | Compact HMI | Small machine applications |
| PanelView 5500 | Advanced HMI | ControlLogix systems |
| Siemens KTP Series | Alternative HMI | Multi-vendor systems |
Conclusion
The Allen-Bradley 2711-B5A1 PanelView 550 is a legacy industrial HMI designed for basic machine control and monitoring in older automation systems.
Despite being discontinued, it remains widely installed in existing industrial environments where stable, simple operator interfaces are still required.
