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. www.festo.co.uk
