Connecting FF Type Pressure Transmitter with Field Communicator 475


Thread Starter


I am unable to connect with pressure transmitter using field communicator 475.

Please help me out for its connection diagram or any other setting in communicator?
If you are testing on the bench make sure you are using a fieldbus power supply and not DC power supply and 250 ohm resistor.

If you are not using DeltaV select Utility form the Fieldbus Application Main Menu. Uncheck "DeltaV System Polling"

With this you should be able to detect the device.

If not, follow the field communications troubleshooting found here: Communication Troubleshooting.pdf

Are you testing this separately on the bench or is it on a running system? In any case the 475 simply connects in parallel with the power supply and transmitter
