The new I/O system in IP65/IP67 enables powerful I/O modules and existing valve terminal interfaces to be integrated in the most important host systems. Based on the innovative AP system communication from Festo, CPX-AP-I ensures continuous communication from the workpiece to the cloud – tailored to your needs!
A bus cycle time of up to 250 μs and a net data rate of 200 Mbaud make CPX-AP-I real-time capable and enable up to 2 kByte I/O process data. This is ideal for fast and synchronous processes. The extremely flexible system is easily scalable with cable lengths up to 50 m. Load and logic voltage supply are galvanically isolated.
CPX-AP-I lets you connect up to 500 modules and valve terminals to standard bus systems. Even existing valve terminals can be easily integrated. Connection to the IoT gateway, easy integration and parameterisation of IO-Link devices, a web server, and an extensive range of functions with the software Festo Automation Suite make your system fit for seamless connectivity!
Configurable I/O modules help ensure that each application is optimised individually with the CPX-AP-I. Cross-communication between modules opens up completely new opportunities for fast applications and decisions. When you integrate the platform in the commissioning software Festo Automation Suite, engineering, condition monitoring and diagnostics will also be easier for you. Continuous communication with all standard host environments is possible at any time, even without engineering tools from Festo! And IO-Link technology can be used without any problem as IO-Link stations can be easily integrated into the system via the IO-Link master and IO-Link device tool. Additionally, CPXAP-I is optimised for current and future industrial Ethernet protocols such as TSN.
When connected to the IoT gateway from Festo, CPX-AP-I communicates via standard cloud protocols such as OPC UA, MQTT and AMQP. This extends the diagnostic options and thus improves maintenance, reduces downtimes and increases overall equipment effectiveness (OEE), optionally via dashboards too. The great thing about it: the system's real-time capability is not affected by handling big data. Smart predictive maintenance features are already available, e.g. switching cycle counter, cable quality monitoring, cable length indication as well as load voltage monitoring. The diagnostics portfolio, too, is enhanced for maximum effectiveness with features such as actuator travel time monitoring, additional commissioning aids as well as advanced connectivity functionalities.

Ready for digitalisation in the age of Industry 4.0
When connected to the IoT gateway from Festo, CPX-AP-I communicates via standard cloud protocols such as OPC UA, MQTT and AMQP. This extends the diagnostic options and thus improves maintenance, reduces downtimes and increases overall equipment effectiveness (OEE), optionally via dashboards too. The great thing about it: the system's real-time capability is not affected by handling big data. Smart predictive maintenance features are already available, e.g. switching cycle counter, cable quality monitoring, cable length indication as well as load voltage monitoring. The diagnostics portfolio, too, is enhanced for maximum effectiveness with features such as actuator travel time monitoring, additional commissioning aids as well as advanced connectivity functionalities.Retrofit for existing valve terminals
The new AP system communication will integrate future valve terminals from Festo seamlessly into your application. Existing valve terminal series such as VTUG or MPA-L can also be easily integrated via the AP interface of the CPX-AP-I. With the added new functions, they can then also be used as switching cycle counters or for load voltage monitoring, for instance. In addition, they can be connected to the cloud. This enables the use of intelligent tools such as dashboards for preventive maintenance and condition monitoring. Another plus point: valve terminals with IO-Link interface, e.g. VTOC, VTUB, CPV, can be connected via IO-Link.
