I have a problem,
SCADACommService make a wrong CRC:
01 03 30 00 00 08 4B 0C
I calc the CRC by using some tools,the right CRC shoud be 0C 4B , and i using 0C 4B send the command can get right result. It will get “CRC Error” when i send using 4B 0C.
How can i solve the problem?
Write to the Chinese that they have the wrong byte sequence in the CRC. Well, if it does not help, you can try to build KpModbus.dll in the new version, where you change the sequence of bytes for CRC, and to call it KpErrorModbus.dll 🙂
