Pneumatic valve terminals connect easily to fieldbus or Ethernet
30 April 2013
Festo has developed a new range of pneumatic valve terminals which allow OEMs and end users to set up pneumatic valve terminals and get connected to fieldbus networks quickly and easily.
With just one entry-level valve terminal users can now go from a multipin connection to Ethernet, through IO link and fieldbus as required.
A comprehensive set of tools has also been developed to offer a complete package so it is as easy as possible for customers to set up the terminals.
The pneumatic functionality of Festo’s VTUG terminal currently includes two 3/2 valves, 5/2 and 5/3 valves as well as pressure zoning, additional supply and sandwich plates and three sizes of valves. More are currently being developed.
The valve terminal is available with a multipin connection, which provides communication through sub D connectors as well as flat cable connectors if required. However, the multipin connection can easily and quickly be changed for an M12 connector to provide an IO-Link connection and a network-ready valve terminal by removing just four screws. This fieldbus independent connection enables extended diagnostics of sensors and actuators above hard-wired connections.
If a higher level fieldbus or Ethernet network is required, a CTEU node can be simply put onto the IO link port. The valve terminal then allows full communication, including diagnostic data and parameterisation of the failure behaviour of the valves.
A quick guide has been produced for each of the CTEU nodes which demonstrates how to use them. These two-page quick guides includes details of DIP switches, wiring diagrams as well as LED status information and tips to help users get their valve terminal operating quickly.
