Allen-Bradley controllogix Logix 5571S Automation Controller 2/1M 1756-L71S/B,Series B.
The ControlLogix controller provides a scalable controller solution capable of addressing many I/O points.
The controller can be placed into any slot of a ControlLogix chassis and multiple controllers can be installed in the same chassis. Multiple controllers in the same chassis communicate with each other over the backplane (just as controllers can
communicate over networks) but operate independently.
ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over I/O links. ControlLogix controllers can communicate over EtherNet/IP, ControlNet, DeviceNet, DH+, Remote I/O, and RS-232-C (DF1/DH-485
protocol) networks and many third-party process and device networks. To provide communication for a ControlLogix controller, install the appropriate communication interface module into the chassis.
