Configurable Digital I/O Module for Decentralized Automation

Festo has expanded its decentralized automation platform with a new configurable digital I/O module and a CC-Link IE Field Basic bus node. These components enable machine builders to reduce hardware variance and integrate decentralized inputs and outputs directly into existing control architectures.

Challenges in Decentralized I/O Architectures
As automated machines become more capable, the volume of required decentralized input and output connections increases. Conventional control approaches often rely on multiple dedicated input and output modules to handle different signal types. This fixed hardware methodology increases the total installation footprint, complicates commissioning, and forces machine builders and system integrators to engineer, stock, and support a higher number of distinct component variants across a single machine lifecycle.

Configurable Channel Architecture
The new CPX-AP-I-16DIO M12 module, described in the file image_47a8a5.png, provides 16 channels that can be configured individually to match specific application requirements. Users have the flexibility to parameterize the module channel by channel, dividing it into eight digital inputs and eight digital outputs, or designating all 16 channels as outputs. When configured for output, selected channels can provide up to 500 mA to drive high-current devices. To streamline immediate installation, the hardware ships with a default 16-input configuration, while output functions are enabled through software parameterization. Individual LED indicators on each channel provide clear operating and diagnostic status to simplify troubleshooting.

CPX-AP-I Platform Integration and Connectivity
The M12 module integrates into the broader CPX-AP-I decentralized I/O platform, which distributes I/O, valve terminals, and IO-Link devices throughout a machine. This high-performance system supports up to 80 modules over distances of up to 50 meters between individual nodes, reducing wiring complexity and allowing for system expansion without redesigning the entire control architecture. Furthermore, Festo has introduced a new CPX-AP-I bus node supporting CC-Link IE Field Basic. This industrial Ethernet protocol expands connectivity for Mitsubishi Electric Automation environments, which are widely utilized throughout Asia. The bus node allows machine builders to retain their existing decentralized I/O layout while altering only the network interface for Mitsubishi Electric systems, facilitating faster machine adaptation for regional markets without requiring additional gateways or custom engineering.

Within the industrial automation market for decentralized IP65/IP67 block I/O, the Festo CPX-AP-I-16DIO M12 competes with flexible I/O solutions such as the Siemens SIMATIC ET 200AL and the Turck TBEN-L series. While traditional I/O blocks lock engineers into strict 16DI, 16DO, or 8DI/8DO hardware configurations, configurable modules allow for dynamic point-level allocation. The Turck TBEN-L offers similar universal digital channels (DXP) with up to 2A per output, targeting heavy-duty actuator loads. The Festo architecture differentiates itself by prioritizing deep pneumatic integration, allowing engineers to mix these configurable digital I/O blocks with IO-Link masters and direct valve terminal connections on the same 50-meter backplane bus. This structural design provides a unified diagnostic and control ecosystem that spans both electrical and pneumatic automation layers without intermediary hardware.
