Five Critical Factors for Selecting Fieldbus Valve Manifolds

Overview:

In today's highly automated machines, fieldbus valve manifolds are replacing conventional hardwired solutions. They more easily perform vital functions by integrating communication interfaces to pneumatic valve manifolds with input/output (I/O) capabilities. This allows programmable logic controllers (PLCs) to more efficiently turn valves on and off and to channel I/O data from sensors, lights, relays, individual valves, or other I/O devices via various industrial networks. The resulting integrated control packages can also be optimized to allow diagnostic benefits not previously available.

Fieldbus valve manifolds from manufacturers such as Festo, SMC, and Numatics find wide utility in packaging, automotive/tire, and material handling applications, as well as in the pharmaceutical, chemical, water, and wastewater industries. They are specified for purchase by controls engineers at original equipment manufacturers (OEMs) who design and develop industrial automation solutions - as well as by end users in relevant industries.

This paper presents controls engineers, specifiers, and buyers with new insights into five crucial factors they must consider before selecting pneumatic fieldbus valve manifolds - commissioning, distribution, modularity, diagnostics, and recovery - while also outlining some shortcomings of conventional approaches. Finally, it highlights new designs that offer substantial improvements in the application, performance, and maintenance of these valve manifolds from the end users’ and OEMs' points of view.
