CTC-Parker Automation (Milford, OH) has created the PC-based Logic Controller, an integrated, modular system built around a unique "bridge" concept to machine control. Conceived to reduce risks and costs, as well as changes for shop-floor personnel, the PC-based Logic Controller (PCLC for short) combines the PLC's rugged reliability, real-time performance, and shop-floor programming languages with the flexibility, upgradeability and open communications of PCs, according to the company.
