Hi to all,
I need one small help.
So I'm testing on Zenon 8.10. connection and read out of Siemens water meter on M-bus protocol.
For master I use Relay PW20, and its connected to Zenon over RS232 cable (setup is the same like on photo in attach).
I managed to communicate and Zenon is reading some value, but I can't read value for the current state of the water meter.
My question is, how to set in Zenon to read the current state of the water meter? Usually you define address of water meter and then change offset value.
What every I put for offset value, I cant read back anything.
Do you maybe have some examples how to set new varijable, and how to define offset value to read data from Relay PW20 master.
