Modbus comunication for PV system
Verfasst: Sa Okt 07, 2023 11:51 pm
Hello,
I have a PV system installed at home, but now I bought a battery, and I need to connect the Grid meter and the PV meter in Modbus RTU - rs485, the battery is the Master Modbus RTU, and the meters are the slaves (address 1 for the Grid side and address 2 for the PV side), I bought 2 Protoss PE11 to connect the meter grid to the Modbus RTU side of the Master, but I cannot connect with it from the Master Side mdbus rtu, I can only connect it with Modbus tcp/ip;
I cannot see it trhou the 1st PE11, that is connect to the Master RTU;
Both PE11 are configurate into TCP Server/Client mode,
Someone may have some ideas for this?
Thanks in advance
