I have some data which is transmitted to TRB 245 via RS 485. I want to upload these data to cloud. But I do not know how to do it.
1. From the web UI, I have seen the MODBUS serial master and gateway. Which one should I use to transmit the sampled data?
2. What does the coil mean in the "function part of a instance"?
3. Which one hold the data from RS 485 D+ and D-?
