Modbus SE3155 Meter - Novodk - 09.05.2024 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? RE: Modbus SE3155 Meter - AlexLV - 09.05.2024 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??
