Why is connection via HART protocol not possible on Endress+Hauser Measuring Instruments?
- SShelby SmithSep 12, 2025
If the connection via HART protocol is not possible with your Endress+Hauser Measuring Instruments, it may be due to a missing or incorrectly installed communication resistor. Install the communication resistor (250 ?) correctly, observing the maximum load. The issue could also be related to the Commubox, which may be incorrectly connected or configured, or have a driver that is not installed correctly, or the USB port on the PC may be incorrectly configured. Refer to the documentation on Commubox FXA195 HART for guidance.
