Modbus TCP App - Server Subscription Error - DL_INVALID_ADDRESS

Hello,

Iam using the Modbus TCP App to configure a Modbus Server. I've successfully set up the primary server parameters, such as the IP address, port, unit ID, etc. However, I encounter an issue when attempting to create a subscription.

I have tried to use both PLC DataLayer nodes, as well as system nodes on the field "Node Adress":

I consistently receive the error message "DL_INVALID_ADDRESS" every time I attempt to save my configurations:

Thanks in advance 😉

Hi,

The "start address" for holding register is wrong. 

Holding Register address range is from 3001 to 4000.

Input Register address range is from 4001 to 5000.

Can you please try using "start address" with the range specified above for holding register.

Also may I know which version of the app is being used.
