The electronic controllers from Festo are modern, compact and versatile PLCs that enable programming with CODESYS according to IEC 61131-3. Different control systems are used in automation technology, depending on the application and the industry. Festo supplies both compact and modular electronic control systems. The compact controllers have all interfaces and functions (e.g. digital, analogue 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.
