For Input Registers you can use "%IWxxxx" Address notation.
Please see attached file more details.
Hope it helps you.
1. 5324 error means "Request is performed without any established connection, that is, Valid of the connected function block is set to false."
Ensure connect block is valid.
2. If your Modscan address is set to 3001 to 3005 while testing, then your Control Builder Modbus Start address shall be "%IW10#3000" and Qty 5
