Article 4.2.1C : What parameters can be seen in LG+1129 through RS485.
Our LG+ 1129 meter have an option to select parameter 1 and parameter 2 in programming page.
Whatever parameter you select in parameter 1 and parameter 2, the same will be displayed in meter and the same data you will get through Modbus registers.
For Example, If you select Watts as parameter 1 and PF as parameter 2 then Watts and PF values will display in meter and the same data you will get through Modbus registers.
Now in a meter, parameter 1 & 2 is selected as Basic Parameters and Wh. Hence only those values you are getting in the meter as well as in Modbus register.
