Motion control is integral to the ControlLogix processor. This highly integrated operation is made possible by the high-speed backplane over which the processor communicates with a servo interface module where the positioning loop and velocity loop are closed. The ControlLogix processor has the motion commands embedded in it. The same RS Logix 5000 programming software that provides ladder logic programming for sequential control provides complete programming and commissioning support for motion control. This approach results in faster development and integration and easy start-up and troubleshooting.
Any single processor can control any particular output module.
You configure the system to specify which processor is to control each output module. The ControlLogix platform provides a rack-based modular assembly. Communication Communication is at the core of the ControlLogix platform. You have the option of adding communication ports by plugging communication modules into the backplane. In the typical configuration illustration, a 1756-CNB module in the chassis local to the processor interfaces the processor to the ControlNet link.
