Smart Instrumentation supports Profibus technology which is based on a two-level bus hierarchy, DP and PA Profibus segments. Each DP bus can connect multiple addressable link hardware devices that link various types of input and output devices. Every link device has a unique node number. The DP link devices that you can connect to a DP bus can belong to one of the following types:

  • Motor drive (connecting a VFD to a DP bus).

  • PLC panel that connects a conventional I/O system of analog and discrete field devices to a DP bus.

  • DP/PA type that connects a lower PA (Process Automation) bus along with its PA field devices to the DP bus (similar to Foundation Fieldbus segments).

Profibus PA

Profibus PA segments and Profibus instruments have the same characteristics as Foundation Fieldbus segments and Foundation Fieldbus instruments.
