The Emerson, formerly GE Automation, VersaMax family features a scalable, modular programmable logic controller and a complete line of highly versatile and robust I/O modules that offer seamless integration with the PACSystems control family, for reliable, high-performance solutions. The modular design of VersaMax addresses a wide range of discrete and process applications. Its innovative modular architecture combines power and versatility to help provide performance in a compact control solution. The VersaMax PROFINET network interface provides integrated I/O to PACSystems controllers in both copper and fiber interfaces. Ideal for any remote I/O application, the PROFINET interface supports ring topology, which permits a node to go down or break without transmission interruption.
