The ControlLogix controller provides a scalable PLC that is that has the ability to address many I/O points.
The Controllogix can be put into any ControlLogix I/O chassis slot and numbers modules can be used in the same chassis. Many controllers in the same chassis can talk with each other over the backplane, but work independently.
I/O can be monitored and controlled with ControlLogix controllers across the backplane, as well as over I/O links. ControlLogix controllers can talk over ControlNet, EtherNet/IP, DeviceNet, DH+, Universal Remote I/O, and RS-232-C (DF1/DH-485 protocol) networks.
The available controllers include: ControlLogix, GuardLogix, and ControlLogix -XT used in extreme environment.
1756-EN2T
The 1756-EN2T ControlLogix EtherNet/IP bridge module operates similarly as the 1756-ENBT but with twice the capacity for strenuous applications. The 1756-EN2T supports:
- Control of I/O.
- Communication via produced/consumed tags and MSG instructions.
- HMI communication.
- Programming and setup, which includes uploading and downloading.
- An adapter for 1756 I/O modules.
- USB serial communication, that allow a computer to access and program a Logix5000 controller.
- A web server to give information about diagnostic and status.
- Switches for fast IP address setup.
