The lightweight CPX-AP-A remote I/O system is integrated directly into Ethernet-based networks that are available worldwide. A variety of additional input and output modules as well as IO-Link master modules
are also available. Pneumatic valve terminals and proportional technology as well as controlled pneumatics that are adapted directly or integrated via AP
communication, can be used to create a scalable system topology. Electric drive technology for linear and rotary movements can be connected via IO-Link®.

The successor to the established CPV, MPA-L/S and VTUG ranges impresses with its high flow rate. And with the communication system AP-I and AP-A, it is the perfect platform for digitised production!

On/off process valves can be automated in different ways using pneumatics. This white paper looks at automation using an individual valve, a valve terminal and a digital valve terminal, and compares the three actuation methods in terms of:

• Required hardware/components and the installation

effort involved

• Investment costs

• Potential for compressed air savings and increased

energy efficiency

• Diagnostic and maintenance options

• Potential for function integration

• Possible applications in safety-related circuits

• Possible applications in potentially explosive areas

The global market for valves and valve terminals today is so large that it is almost impossible to maintain an overview. Often, price seems the only buying criterion. But it pays to look more closely, particularly with regard to higher productivity and process reliability. Users of Festo's attractively priced and long-lasting high-quality valves benefit in tough everyday practical applications from the meticulous development processes, including numerous simulation tests and the correct choice of technologies and materials.

 This White Paper provides information on:

• Care pays for itself: the development process of valves and valve terminals
• Caution: not all manufacturer data is comparable 1 to 1!
• Small differences with a great impact: how to choose the right valves/valve terminals

When valve terminals are used, short-circuit and short-circuit detection of the safe output modules of the Siemens ET 200 SP may result in diagnostic interrupts. These diagnostic interrupts can lead to the fact that an operation is not possible. This technical report explains the background and suggests possible solutions.
