Hi. I have set up communication with Rievtech PLC unit. Now I am facing two issues with it.
First one is with coils addressing. My coil addresses on PLC are 1536, 1537, 1538, 1539. Rapid Scada is reading 1536 adress in the 1537 cell and so on. So in Scada they appear 1537-1540.
As a second problem, I cannot read any of the holding registers. If I set up registers from 3072 to 3080 they all are being read but returning all zeros. Those addresses definitely hold values as I can read them on HMI.
I would be happy if anyone could help me to get on the right path, thank you.
