Festo's electronic controllers are modern, compact and versatile PLC controllers that enable programming with CoDeSys according to IEC 61131-3. Different control systems are used in automation technology, depending on the field of application and industry. Festo offers both compact and modular electronic control systems. The compact controllers offer all interfaces and functions (e.g. digital, analog signals) in one housing and are designed for small to medium control tasks. The modular controllers can be expanded very flexibly and are therefore designed for the medium and upper power range.
