Hello AlextUT,
Well, it helps a little bit, because if you are right at least I know that I cannot use MODBUS and debug at the same time
I made some changes in ladder. I've disabled network 2 on my Jazz 20-R31 (Slave). Now, I'm able to write data from V1210 to Jazz 20-R31 (Slave), but I cannot read any data from it. Even if I write data to Jazz 20-R31 (Slave) successfully, I'm still getting status message #5 - No Communication.
I've improved a little bit, but still it's not working properly and I'm out of ideas. Any help is needed.
Regards,
Giedrius K.
