ControlLogix system components
ControlLogix control system to microprocessor as the core, the advanced control technology, communication technology, computer technology, CRT technology and field instrument organically combine to achieve the production process of centralized monitoring, centralized operation and decentralized control, provided for the production A strong guarantee. Because of the system's memory, the number of controllers and the type of network can be selected according to the specific application, so compared to other programmable control system, its structure is more flexible, more convenient to use.

The core of the ControlLogix system is the Logix5550 controller, which operates at a rate of 0.08 ms / K, with a standard memory configuration of 160 kB, expandable to 2 MB, and a Logix5550 controller supports 12,800 discrete or 4 000 analog I / O points, IEC1131-1-compliant operating system provides a multitasking environment with up to 32 tasks, 31 of which can be set by the user, support for long files, variable names [1]. Logix5550 to the microprocessor as the core, using advanced process control technology, communication technology, computer technology, is responsible for the production process to detect and control, is the data acquisition, process control part. Through the configuration and programming, with a wealth of motion control, sequence control, drive and process control functions, computing functions, can be directly collected from the scene of the various process data, after processing, operation, the detection signal sent to the operation Station to monitor, the control signal sent to the scene. With high reliability, high scanning rate and other characteristics, and has a self-diagnostic function.
