The XC controllers with Controller Development Software (CoDeSys) provide fast, cost-efficient control for global food packaging, renewables, and HVAC applications. The modular XC programmable logic controllers (PLCs) are scalable to meet individual and evolving automation system requirements for small- and medium-sized systems. The PLCs include XC100 and XC200 devices. In addition to the RS232 interface and CANopen fieldbus connections, the XC200 controllers have an Ethernet interface and an optional integral Web server for situations where additional communications and high-processing capacities are required. Ethernet access provides both efficient communications between controllers and data exchange to high-level control systems, using communications standards including Object Linking and Embedding (OLE) for Process Control (OPC). Providing customizable control, XC controllers are easily expandable with compact, high-speed input/output (I/O) modules.
