I'm new here to this forum, but i am working for a long time with IFM PLC's and codesys 2.3
but now i have a machine i like to read out and control via J1939, it has J1939 protocol but with custom bytes. see attachment.If i use the J1939 SPECIFIC REQUEST it delivers a DWORD what will not do the job. Any one any ideas how i can read these messages with codesys 2.3? Any idea's are very welcome.
