Allen Bradley 2711R-T7T/B PanelView 800 Series 7-inch Touchscreen Human-Machine Interface Terminal

Q: Which controllers does the 2711R-T7T/B primarily work with?

A: It is most commonly used with Rockwell's own Micro800 series small PLCs to form a cost-effective small control system. It also connects well to medium to large controllers such as the CompactLogix 5370/5380, meeting the needs of medium-sized applications.

Q: What types of industrial networks does this touchscreen support?

A: It supports Ethernet and serial communication. Ethernet is mainly used for high-speed communication and remote access with the PLC, while the serial port (RS-232) can be used to connect older controllers or other devices with serial ports.

Q: What are the main differences between the A-series and B-series of the 2711R-T7T?

A: The most significant difference is that the B-series does not support the DH485 communication protocol. If you are using B-series hardware (usually pre-installed with firmware version 8.011 or higher), it will not support DH485-based networks and will only be able to communicate via Ethernet or serial ports. Special attention is needed when replacing or selecting a project.
