Hi all,
I have a DT80 series 4 , I want to connect a Power analyzer with RS485,
Protocol communication: Modbus RTU
• Baud rate : 4.8, 9.6, 19.2 kbps
• Parity number: Odd, Even, None
• Stop bit: 1,3
• Address: 1-247
• Connectors : 4 pole terminal ( integrated 120 Ohm terminator on T terminal ),
So, I need your help for the configuration using dEX 2

Hi boucetta,

MODBUS syntax must be constructed manually depending on sensor address and the parameter you want to read (register location, data type etc). If you can send me sensor information on parameters location I can give you example to construct one MODBUS syntax.

Best regards,
Rudy Gunawan

Dear Rudy
Thank you very much for your reply.
Please find here my sensor communication protocol, in the link below

Thank you for your time

Hi boucetta,

Based on the manual, it seems you have to set the port (baud rate, data bits etc) as well as sensor address. Please take a note on that setting so you can use them within DT.

Looking at the register list (below), you need to pay attention on register address (change it to decimal - from hexadecimal), 2x word (it means it will utilise 2 register) and format which is long integer (use MBL option in DT).

Best regards,
