Modbus SE3155 Meter

[Novodk]

I need some help getting this SE3155 meter connected/configured to work with my LM

I have connected:

Meter D0 -> LM A
Meter D1 -> LM B
Meter 0V -> LM GND
Meter settings is:
38400 Baud rate
Parity: None



I have added the Device like so:

But the log just says: Read failed, Operation timed out!

What am I doing wrong?

Hi,

just to check - by default your EL Modbus Meter ID (Slave adress) =1? (You put =1) This is very important. It depends from device. For some others it could be 254 by default.

If you have many of meters or other devices connected to line - individual adress should be set for every device and also the same communication parameters for all line devices.. If you will have 2 or more the same adreses - communication will not work.

Any other devices are connected??

Hi Alexander, thanks for the reply, I have only 1 modbus device connected atm
I will try with another Slave address just to be sure, then Ill try the other RS485 port on my LM
