Hi,

I am trying to link the J1939.Engine.Total Fuel Used parameter to a Text Gauge but PVC crashes reporting the following error message:

Error Message:

the same happens on two other PCs using WIN XP SP3 and WIN 7 instad of WIN 10. So far no problem with all other parameters we need. Thank you.

Kind Regards

guidofor,

We suspect there is something in the configuration that has caused this. Perhaps a bad units or units conversion for that parameter. Could you send me the configuration by Private Message so we can find the root cause?

Thank you,
Boyce

Thanks a lot,

yes you are right, eventually I realised it when trying to validate the configuration because I got an error message complaining about the invalid unit of measure I for the variable. I don't know if it means an uppercase i or a lowercase L. So adding the correct unit of L (Litres) has resolved the problem but it is strange anyway since when adding the parameter to the engine device, that strange unit of measure gets assigned automatically only for PGN 65257 while for all other PGNs units are assigned correctly and automatically.

Kind Regards

guidofor,

Thank you for the information. I'll enter a bug report and we'll get that unhandled exception taken care of.

Thank you,
