【英文介绍】

The Allen-Bradley 1756-L55M22 is a ControlLogix controller that is a member of the Logix5000 family of controllers. It has 750 KB of data and logic memory, 208 KB of I/O memory, and integrated non-volatile backup memory. The 1756-L55M22 has 2 cpus, a Logix and a backplane, which distribute resources between them. Application code and messages are executed by the Logix CPU, from which the backplane CPU sends and receives data and communicates with I/O.

The 1756-L55M22 controller is connected to a workstation or other controller via a serial port. The 1756-CP3 serial cable is used to connect the controller to the workstation. In order to communicate with other devices, it uses various networks such as Ethernet /IP, ControlNet, DeviceNet, etc. The 1756-L55M22 can generate and use system share tags over EtherNet/IP or ControlNet networks. The producer and consumer systems each require a connection.

The 1756-L55M22 controller has multi-tasking capabilities to allocate processing time to different operations in the application. It also contains programs for grouping data and logic. It provides routines that encapsulate executable code in a programming language. It supports both online and offline Logix5000 programming language. If any I/O communication failure occurs, it has a blinking green I/O LED. It also contains a fault handler for diagnosis. The 1756-L55M22 supports 1756-BA1 or 1756-BATM batteries and requires regular maintenance.
