Function and Working Principle
The 2711P-T4W21D8S operates as a visual interface between operators and PLC systems:
- Connects to ControlLogix / CompactLogix PLCs via EtherNet/IP.
- Displays real-time machine data, alarms, and status screens.
- Allows operators to send basic control commands (start/stop, setpoints).
- Runs applications created in FactoryTalk View Machine Edition (ME).
It does not directly control equipment, but acts as a communication and visualization layer between operator and PLC.
