What to do if HART communication does not function on Endress+Hauser Levelflex FMP51?
- KKevin MeyersSep 12, 2025
If HART communication isn't working on your Endress+Hauser Measuring Instruments: * A communication resistor might be missing or installed incorrectly. Install the communication resistor (250 ?) correctly. * The Commubox could be connected incorrectly. Connect the Commubox correctly. * The Commubox might not be switched to HART mode. Set the selection switch of the Commubox to the HART position.
