Modbus holding address

Post by mmercalde » Sun Dec 29, 2019 3:46 pm

Hi,

I am designing a panel to interface to a Schneider Electric inverter through Modbus tcp/

In the settings I am unable to enter an address lower than 400001. The Schneider modbus map for this device specifies the first holding address as 40001.

Is there a work around? I have already attempted to use that as the offset

Thank you

Hello,
Suppanel uses 6 digits Modbus addressing and your Schneider manual uses 5 digit address.
To convert from 5 to 6 just insert an extra 0 after the 4, then 40001 on the manual will be 400001 for Suppanel.

Hope it will work.

Thanks for your inquiry.
