A temperature controller module sends data as RS485-Modbus Ascii code. When used putty 2400bps,parity-None,stop bit-1. Data shown as 0036 0030$* 0036 0030$* 0036 0030$* on serial monitor of putty. I need to get this information to PLC. But I do not know Modbus station ID, Address.
Is there is a way to find unknown device's Modbus station ID & Address?
I used Modscan, Modbus Poll but no success.
