A field bus solenoid valve assembly has a sensor for detecting the commencement of an actuation cycle for moving a piston in a cylinder and piston assembly. A position sensor detects an end position of a piston in a cylinder and piston assembly at the end of the actuation cycle. A timer times the elapsed time between the initiation of the actuation cycle of the piston and when the position sensor for detecting an end position detects the piston in its end position at the end of the actuation cycle. A comparator operably connected to a storage device and the sensors for comparing elapsed time from the sensors to a normalized time or profile and a predetermined tolerance boundary in the storage device. An alarm device is actuated if the elapsed time is outside of the set tolerance boundary.

A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.

A valve driver system for driving a plurality of valves of a valve manifold. The system includes a plurality of valve drivers, wherein each valve driver is configured to drive a zone of one or more valves of the manifold; and, a power board that separately powers the respective valve drivers such that the valve drivers are powered separately with a separate power source that can individually power the valve driver.

A zoning adapter for adapting logical addresses of valve drivers to physical addresses of valves of a valve manifold. A conversion portion converts logical addresses to physical addresses of the valves in the different zones of the valve manifold with a spacing in one or more portions of the logical addresses.

A valve island has at least one valve module and an adapter module, wherein the adapter module includes a first data line and a first voltage supply line, which each extend continuously from an interface on a first front side forming an outer side of the adapter module to an interface on a second side of the adapter module pointing into the valve island.
