Modular, highly flexible and high-performance

Would you like to flexibly combine remote I/O systems with electrical and pneumatic automation? And are you also looking to adapt the automation architecture of your machine to your individual design philosophy while generating as little cost and effort as possible?

Our modular remote I/O system CPX-AP-A is the answer to these questions and your requirements. Modern automation topologies ensure free and seamless connectivity, embedded in future-proof and compatible concepts for the flexible automation of entire machines or individual machine modules. And this is independent of the network used and without restrictions: pneumatic and electric, communicative and intelligent – perfect interaction, right through to the cloud.

1. Feldbus module

  • For communication in Ethernet-based networks
  • Communication interface to other AP participants
  • Can be positioned freely and independently of the 24 VDC power supply

2. Intelligent end plate

  • Cost-effective and compact AP interface for additional AP participants
  • Real-time communication with 200 MBaud data rate and 250 μs cycle time

3. Input and output modules, IO-Link Master

  • All modules can be combined as required and flexibly connected in series
  • Digital and analog input and output modules up to 32-way in the future
  • IO-Link Master for IO-Link® devices from Festo and third-party suppliers

4. Interlinking blocks without infeed

  • Transmission of voltage and communication between modules and to the valve terminal
  • Connection to each other using self-forming angled fittings

5. Interlinking blocks with power supply (24 VDC)

  • Power supply for I/O modules and valve terminals (system and load voltage)
  • Additional load voltage supply for outputs and valves, for creating voltage zones
  • Forwarding of system voltage for additional AP participants or external components

6. Pneumatic interface

  • Connection between remote I/O and attached valve terminal
  • For VTUX and MPA-S: flat plate silencer, compressed air supply port and auxiliary pilot air
  • With VTSA: module slot for any I/O module, optional voltage feed/forwarding

7. Valve terminals

Valve terminal variants with full range of functions mounted directly on the remote I/O

  • VTUX: highly modular
  • MPA-S: very compact
  • VTSA: sturdy and powerful

Separated system voltage and load voltage

8. Material selection

Modules and interlinking blocks are made of sturdy, high-quality polymer with fiberglass

  • Flame retardant and halogen-free, suitable for welding applications
  • High electromagnetic compatibility

Metal is used wherever necessary because of standard requirements or for assembly

  • Metal sleeves for shielding on plug connectors
  • Connectors at the system supply
  • Metal fittings, end plates and mounting elements

Remote I/O with CPX-AP

The remote I/O system CPX-AP, comprised of CPX-AP-A and CPX-AP-I, enables the connection of large amounts of I/O and pneumatic valves to the industrial network via a single Ethernet address. Connect a CPX-AP bus interface to the Ethernet network, then connect any number of CPX-AP input/output modules, IO-Link® masters, and valve manifolds to the bus interface (up to 80 participants per bus interface). This greatly reduces the number of IP addresses that must be configured, which saves time, and reduces the cost of having an Ethernet switch in every device, which saves money. The maximum distance between AP participants is 50 meters, which allows machines of any size to be efficiently fitted with remote I/O and valves. If a system needs to expand beyond 80 participants, additional bus interfaces can be easily added.

Decentralized remote I/O terminals CPX-AP-A

The automation system CPX-AP-A is the successor to the formidable CPX terminal-based I/O and integrated valve platform. CPX-AP-A combines inputs, outputs, IO-Link masters, and pneumatic valves onto a single, integrated, remote I/O terminal. Each terminal can connect to other CPX-AP-A terminals as well as CPX-AP-I remote I/O modules over the common AP backplane communication string, enabling seamless integration and an unprecedented level of flexibility in system topology. With real-time data rates of 200 Mbps, up to 15 modules per terminal, bus interfaces that support the most important industrial networking protocols, and functionality that extends data connections into the cloud, CPX-AP-A provides the ultimate in remote I/O and valve connections for the most demanding machines and system designs.

  • Expandable: up to 15 modules per terminal including I/O and valves
  • Flexible: mix-and-match CPX-AP-A terminals and CPX-AP-I modules via the common AP backplane communication technology, all under one bus interface
  • Easy: seamless integration into the most common host environments including PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, and PROFIBUS
  • Powerful: direct integration of Festo valve manifolds, on-terminal or via AP cable
