What is the Modubs Register for Digital Input 1 (DI1) for a 7650
Issue
What Modbus register should be used to read Digital Input 1 (DI1) on an ION7650 meter?
Product Line

Environment

Cause
Not all ION modules have a hard‑coded Modbus register. DI1 on the ION7650 is one such case.
Resolution
- Map the DI1 module’s State output to a Modbus Slave register, then read that Modbus holding register from your master.
Note
ION7650 is discontinued, the recommended Schneider Electric replacement is ION9000 series.
