How can I temporary disable a CRC-check to locally reproduce a parsing issue in a serial driver?

Hi Dojo

A user experienced a parsing issue on parameters 1305, 1306 and 1307. I want to reproduce the issue locally by using a serial driver and testing it with several inputs. As a consequence the CRC-value at the end of the response needs to change as well. Since this is not the core of the problem, I want to temporary disable this check to test if my fix works.

Can someone of the community help me with that, please?

Thank you in advance!

Kind regards

Hi,

You can do this by altering parameter 6013, where Dataminer performs the CRC-check on the input. If you put the CRC-tag in comment as indicated in the screenshot, the CRC-check will not be done and you can debug the parsing issue easily.

After debugging and fixing the issue, uncomment the tag again, as the CRC-check is an important asset in the error detection in serial communication.

Kind regards,
Joachim
