mapping Modbus RTU between ABB UNO 3.3 and React-MTR-1PH
Hi Flavio,
I have an ABB UNO 3.3 kW with a meter React-MTR-1PH (interface RS485 - Modbus RTU).
In last week I buy another, an ABB UNO 6.0KW, a meter React-MTR-1PH and an UNO-DM-PLUS ETHERNET COM KIT.
At this moment, I have a microcontroller to read data of meter react by the interface WiFi ABB (dashboard). With this information, I turn on or turn off some equipment in my home. But this way is a little slow, 5 - 10 sec to refresh the data.
So, I try to read directly protocol Modbus RTU between ABB UNO and meter React. Below some messages.
I check the CRC 16 (last 2 bytes), and this is correct. I can't find on the Internet the mapping address to Modbus RTU (ABB UNO). So, I can't understand the information in the messages.
Can you share the mapping address Modbus RTU between ABB UNO and meter React ?
Thank you very much,
Jorge Torres
