enter image description here

  • I want to add 0 between the two four number in the plc address you see in the picture.

Should I use left shift?

Can u help me ?

PLC Address = 404606 --> I want value

Plc Address = 440606 --> value shown to me


Solution

  • Good ol' Modbus. After re-reading your question, I believe you are trying to target Application Address for Holding Register 404606. The edit control is wanting the decimal wire offset of the Holding Register (e.g. for 40020, you would enter 19).

    So, to get HR 404606 for the PLC Address static text, you want to enter 4605 in the edit control.
