Traditional PLC system in the event of system failure, there is no perfect mechanism to ensure the safety of control, the safety PLC based on heterogeneous dual-processor redundant structure can meet the requirements of industrial control for equipment and personnel, improve the reliability of industrial control. In this paper, according to the operation requirements of safety PLC based on heterogeneous...
There are many function modules in the numerical control (NC) system, the system needs to communicate with each other through the data interaction among modules, to coordinate the work between modules and complete the control task. In this paper, the main function module structure of NC system is constructed based on RCS method. The communication between the NC system modules is realized by using...
