Festo Launches CPX-AP-A Intelligent End Plates EPLI/EPLI-S for Gateway-Free Remote I/O Expansion

OEM machine platforms evolve as additional zones, modules, or downstream cells are integrated into the original control design. When remote I/O extends beyond its initial boundary, added gateways, new Ethernet addresses, and separate power distribution increase wiring complexity and commissioning effort.

To simplify scalable machine architecture, Festo introduces intelligent end plates for the CPX-AP-A remote I/O platform. This solution extends system communication, diagnostics, and power across multiple machine zones with no cabinet rewiring or added gateways.

EPLI and EPLI-S

Intelligent end plates EPLI and EPLI-S extend the AP backplane, enabling connection of additional modules without introducing gateways or consuming additional network addresses. EPLI extends AP communications and system power to downstream modules. EPLI-S adds direct power supply for downstream modules.

Machine builders can scale remote I/O systems across independent machine sections without redesigning controls or duplicating power and networking connections. I/O and pneumatic valves can be placed at the point of use. Maximum distance between modules: 50 meters.

CPX-AP-A Platform

CPX-AP-A remote I/O modules are based on over two decades of Festo expertise in distributed valve and I/O systems. Modules can be mounted together in a cabinet or placed individually across the machine, all appearing as one system to the PLC.

The AP architecture consolidates dozens of functions under a single industrial Ethernet address, reducing network complexity and controller overhead while maintaining high-speed communication and unified diagnostics across all machine zones. Festo’s design preserves AP performance, bandwidth, and synchronization through each module. Visit Festo at www.festo.com for full specifications.
