What to do if I can't change parameters on my Endress+Hauser Measuring Instruments?
- K
  kevin40Aug 2, 2025
  If you cannot change parameters, consider these points: 1. Some parameters are read-only and cannot be changed. 2. The hardware write protection may be enabled. Disable write protection. You can check the write protection status via the WRITE_LOCK parameter in the Resource Block. 3. The block operating mode might be incorrect. Change parameters in OOS or MAN mode via the MODE_BLK parameter group. 4. The value entered may be outside the allowed range. Enter a suitable value or increase the input range if possible. 5. For Transducer Blocks, the programming level might not be enabled. Enable it by entering the code in the "Un-/Locking - Access Code" parameter or using the Service Code.

How to troubleshoot a faulty connection to the fieldbus host system with Endress+Hauser Proline Prowirl 72?
- C
  campbellrobinAug 8, 2025
  To troubleshoot a faulty connection to the fieldbus host system, check the following: - Data lines - Pin assignment / wiring - Connection between connector / fieldbus port, ensuring the coupling ring is tightened correctly - Minimum bus voltage of 9 V DC at terminals 1/2 (permissible range: 9 to 32 V DC) - Permissible fieldbus length and number of spurs - Basic current of at least 16 mA - Bus address to avoid double assignments - FOUNDATION Fieldbus network termination with a bus terminator at both ends of each bus segment - Current consumption of the bus segment, ensuring it does not exceed the maximum permissible feed current of the bus power supply unit.

Why is there no display visible on my Endress+Hauser Proline Prowirl 72 Measuring Instruments, but the connection to the FOUNDATION Fieldbus host system is established?
- D
  David WrightAug 14, 2025
  If there is no display visible, but the connection to the FOUNDATION Fieldbus host system has been established, check if the ribbon-cable connector of the display module is correctly plugged into the amplifier board. If it is, the display module or the electronics may be defective, and you may need to order a spare part.

Why are the manufacturer-specific parameters not visible in the Transducer Block of my Endress+Hauser Proline Prowirl 72 Measuring Instruments?
- J
  Jessica GardnerAug 27, 2025
  The manufacturer-specific parameters are not visible because the device description file (Device Description, DD) has not yet been loaded to the host system or the configuration program. Download the file to the configuration system.
