ControlLogix 5570 Controller | PN: 1756-L7XX

The ControlLogix controller is part of the Logix 5000® family of controllers:

• ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over networks.
  ControlLogix controllers can communicate over EtherNet/IP, ControlNet®, DeviceNet®, and many third-party
  process and device networks.
• 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.
• To provide communication for a ControlLogix controller, install the appropriate communication interface module into the chassis.
• ControlLogix 5580 controllers have a built-in EtherNet/IP port, but you can also use communication interface modules in the chassis.
