Hi All,
I'm using V350 and trying to pull data from power meter through modbus 485.
But I face the problem that cannot receive any data from power meter. I believe that the communication is failed.
I'm not sure about the modbus configuration block setting for COM port 1,2 and 3. I confused my usb is which COM? my Modbus RTU is which COM, I also added 1 TCP ENTHERNET card. which means I have 3 ports. I don't know how to do the setting for it.
Beside, I also don't know what is my plc network id. how to set it?
My power meter address is 3
boud rate is 9600
Even, stop bit 1.
I'm success to pull data from power meter using modscan.
Can someone explained to me?
