MODBUS TCP slave in Ewon flexy

I define a memory Tag in ebuddy and I want to assign it a register in Modbus TCP slave
But I don’t have any data in assigned address

Hi HamiRahimi,

With the Ewon publishing tag values via Modbus TCP, the register number selected is in the analog output holding register range starting at 40001. So when you set register 502 as in your screenshot, you’ll actually need to read register 40502 when connecting the Modbus TCP master to the Ewon.

Best regards,
