downloaded trial version of Advanced Serial Data Logger 3.6.4.507 and MODBUS RTU Module plug-in.
When I tried to define Data Query I received "x" instead of "v" in "Send request, otherwise parse response only" line (screenshot is attached)
What could be a problem?
This isn't the problem. Just another view of "v".
Thank you for answer. I'm trying to check the communication now -
30/07/09 10:19:45 MODBUS RTU. Invalid CRC (00,F020)
Could you attach a screenshot with the main program window (with data).
Attached
I'm sorry, but now the screen isn't useful (my mistake). Please, use the following data view settings.
