Hi Giovanni,
What’s the meaning of such parameters?
there was a discussion in the past regarding the parameters for serial communication:
Matching Serial Port Parameters on SG3 and SG4 PLCs - Ask Questions / B&R Software & Runtime - B&R Community
For what I see you have wrong checksum on the message so we can’t consider valid the data inside the frame.
>Could be the road to success or not? Frankly speaking I am a little bit in doubt..
Think positive, at the end the cause of the problem could be related to wrong or missing parameters on MBSOpen()
======================================
Around 20 years ago I did something similar on what you are doing, in my case I used 2 X20 CPU and I installed the 2 examples you see in the help Examples in ANSI C.
In that moment I didn’t have a serial sniffer in the office, I configured in the mode RS232 and worked with no issue. We use DRV_mbus library in many projects so I don’t think there
is an issue on that.
Ciao
