Allen-Bradley ControlLogix

Allen-Bradley ControlLogix is a modular automation platform for discrete, process and motion control. Its chassis-based architecture combines 1756 controllers, I/O modules, communication modules and power supplies on a shared backplane. Local I/O connects field signals directly to the chassis, while network interfaces support distributed I/O, drives and other controllers. Controller generations differ in processing capacity, memory, supported networks and motion capabilities. Applications use the Logix programming environment with tag-based data and configurable tasks, programs and routines. Digital, analog and specialty modules provide signal acquisition, output control and diagnostics. Suitable system configurations can add controller redundancy, while safety applications use the corresponding GuardLogix hardware. Typical functions include equipment sequencing, process regulation, coordinated motion and communication with plant supervisory systems.
