Both Profibus PA and Foundation Fieldbus share the same Physical layer definitions. Therefore the connection and power equipment that Relcom makes will work identically for both types of busses. The difference is in the protocol.

Therefore, our FBT-3 Fieldbus Monitor will not work with Profibus PA as it was only designed for Foundation Fieldbus. Please see our Links page for URLs to the standards organizations for more information on these busses. More.
