Apparatus and methods to communicatively couple field devices to controllers in a process control system

摘要

Apparatus has a first interface to be communicatively coupled to one of a first field device or a second field device. The first interface communicates using a first communication protocol when coupled to the first field device and communicates using a second communication protocol when coupled to the second field device. A second interface communicatively couples a bus to a controller in a process control system using a third protocol different to the first and second protocols. The type of protocol to be used may be automatically detected.
