PC-based control replaces the traditional and proprietary controllers such as programmable logic controllers with standard PC-based hardware and software. PC-based control runs on personal or industrial hardened computers. This approach provides users with a system with built-in diagnostics, real-time simulation, and consolidation of data into a single database. CNC machines, robotics and laboratory systems are just a few examples of PC-based control applications.

Optimation provides PC-based control implementation services. PLC and PC-based controls technology can be mixed and matched to meet the needs of many industrial applications. Three factors have affected the growth of PC-based controls: the Internet, the increasing reliability of operating systems, and the decreasing cost of microprocessors. Often, integrating PC-based control with human-machine interface (HMI) technology can benefit a plant floor system.
