A process control system manages fluid processes in a factory plant. It typically reads temperatures, speeds, etc. from the plant via smart sensors and adjusts the process via smart actuators like valves and motors. In many cases the control system and the smart devices are from different vendors. Fortunately, industry standards have been established for the communications among them. These standards are based on wireline networks; they are no longer suitable for wireless networks. In this paper we discuss the interoperability issues related to wireless communication among process control system components.
