Digi one IAP Reading Modbus 3x inputs

I’m interfacing a flowmeter using a DOIAP and I need to read several 3x registers starting at address 307002. The Digi One IAP assumes that AB file numbers N250 to N255 map to these. That means only to 30600. How is it possible to read registers 307002 to 307500?

Jacques, those values are outside of our support range. You look at the application guide Digi protocol bridging calculator for the master in your setup. See URL below.
