Remote Access to Instrumentation using HART

Have you ever had a device in a hard to reach or remote location stop working or behave oddly? It is costly and undesirable to have to either climb a tank or drive to a remote location and check on an instrument or positioner that may or may not be giving accurate data.


The beauty of modern instrumentation is that it already has the capability to communicate and send diagnostic data via HART. All you need is a HART-enabled input/output card or multiplexer and a way to get that data from the PLC/DCS/RTU to you where you are. When you have the communication path, you can get the data and diagnose and/or make changes to the process instrumentation and save a trip. This saves time, increases safety, and maximizes your effectiveness.
