The new Festo CPX-terminal has been designed for flexible connection of pneumatic and electrical control loop systems to automation systems. This enables control of the entire pneumatic control loop system with I/O modules and valves at a single fieldbus connection. The CPX terminal assures optimised linking to the control concept via a wide range of fieldbuses, including CC-Link. Bus connection is possible via a terminal strip with IP20 protection class, sub-D connector, T-distributor and connection of an incoming and an outgoing bus cable. Integrated interfaces are with RS485 transmission technology. CC-Link enables communication at the control and fieldbus levels between data and field devices such as control systems, sensors or actuators with up to 65 stations without using repeaters.
