Decentralized I/0 modules to optimize functionality

August 21, 2023

CPX-AP-A distributed I/O has modules attached within a terminal. CPX-AP-I is Festo’s decentralized I/O where modules are connected via cable at distances of up to 50 meters (164 feet) between modules. AP modules, whether on-terminal or individual, are IP65/67 rated and can be located in cabinets, in clusters around the cell, individually placed or separated at great distances. Every AP module features a high-performance real-time backplane transmission rate of 200 Mbps full duplex.

AP gives machine builders the freedom to optimize the machine or cell by adding I/O where they need it, and in ways that will best boost performance and diagnostics capabilities. The AP ecosystem makes it efficient for end-user customers to add functionality as needs arise.

Whether physically attached on-terminal or connected via cable, all components such as PLCs, valves, motors, drives and I/O appear to the programmer to be incorporated within one smart terminal under a single IP address. Having the entire distributed and decentralized I/O topology under a single IP address significantly reduces hardware and installation costs while lowering system complexity. Since many PLCs come with a limited number of IP addresses, the Festo solution means more capabilities are possible per PLC.
