Modbus Framing Incorrect
Modbus Framing Errors:
There was a bug in version 5.1 of NetDecoder that calculated the beginnings and ends of Modbus Frames incorrectly, resulting in NetDecoder displaying correct frames as broken.
This is fixed in version 7.2 and later. If you have version 6.x, please download version 7.2 or later.
Download the attached file ste, execute it and the problem should be fixed.
