Developed to provide robust wireless communications to eliminate the need for network cabling, one single, master network node is capable of connecting up to 127 wireless slaves.
According to Bob Hitner, marketing manager at SMC UK, “This product is unique in the market, the first of its type, and leads the wireless control of pneumatic technology. It was officially launched in 2018 and it’s already been purchased by several leading organisations in the UK.
“This product was produced following a conversation with one of our customers – a well-known Japanese automotive manufacturer with a major production plant in the UK – who asked us to specifically look at an application using several robots. They wanted to eliminate the issue of production downtime due to communication cable failure within a robot.
“While power and air can be supplied very robustly in a robot through the robot arm, the problems associated with fatigue of a communication cable is an industry-recognised issue. Obviously, in an automotive application the loss of production due to cable fatigue is hugely expensive.”
The EX600 wireless product now provides seamless communication to intelligent valve islands, with integrated digital I/O in applications known to be problematic when using industrial networks such as tool changing, rotary table automation and robot applications. Prior to its official launch, the wireless valve manifold was put on long-term test and it has proved to be extremely reliable in eliminating stops in production due to communications cable failure.
One of the first companies to consider using this new product was Fanuc UK, which asked to trial this product on a small pick and place robot cell, including load/unload tables, equator inspection and vision-guided pick conveyor for unloading a CNC machining centre with a centrally located robot.
Fanuc’s feedback quickly confirmed that considerable time was saved in both the design and production process. While the cost of the wireless solution was slightly higher, this was largely offset by not having to build a robot with a comms cable. Cable maintenance is no longer required and the manifold’s integrated web server function provides diagnostic information to identify potential system faults.
Marc Budd, project manager at Fanuc (UK) Ltd, said, “We strive to use new technology to provide our customers with the most up-to-date solutions. SMC’s EX600 wireless valve manifold is a cutting-edge product that can help you save design, production and commissioning time. Its web server function means that the master can be accessed from remote locations so that fast fault-finding and diagnostics is ensured, saving both time and money.”
