Foundation Fieldbus H1

Foundation Fieldbus H1 

A fieldbus is an all-digital, serial two-way, multi-drop communication System.
Which will be used in industry to replace the existing 4 -20mA analog signal.
H1 (31.25kbps)interconnects field equipment(Sensors, Actuators & I/O).
HSE (High Speed Ethernet, 100mbps) provides integration of high speed controllers, subsystems (via Linking Device) and data servers and workstation.
A fieldbus consists of two wires.
The digital signal can be transferred as a voltage difference between the wires or as a current value.
Fieldbus allows “multiple variables” from each device to be brought into the control system for archiving, trend analysis, process optimization, reporting, predictive maintenance and for asset management.
