Good morning,
I'm trying to integrate a smart energy meter from the company that supplies electricity in Portugal (E-Redes).
I have already managed to integrate most of the values through a Schneider Electric AS-P PLC using the RS-485 port in modbus RTU, values shown in the image attached.
Settings used:
Baudrate: 9600
Parity: None
Stop bits: 2
Now I'm trying to use LM to read the same values.
I started by creating a profile and I can read the long unsigned variables, however I am not able to read the double long unsigned variables.
Can anyone help?
Attached is an image of the correct reading of a long unsigned (Voltage L1) and the non-reading of a double long unsigned (Active Energy Import Sum).
Attached I also leave the settings I have in the PLC for the variable (Active Energy Import Sum) that I am not able to read in the LM.
Attached I also leave the profile that I have unitl right now.
Below is the E-Redes document with the HAN protocol specification, if you need to consult it
