You can add a AD120 as a modbus meter:
Register Address 40960
Format: 4 Byte Integer

Are you sure? From my analysis of the register spreadsheet, it looks like register 40960 (decimal. HEX is A000H) on the third sheet, - note it is a kWh register.

And based on the fact the next register is 2 places on, it looks like a 4 byte integer. (2 modbus registers). Therefore the Format is in my opinion a 4 Byte integer. Not sure of the endian format of that, you must play around with that and see what you get.

Also, the scaling seems to be a ratio of 1/100, so you have to set the multiplier in Meter Details to 0.01 or 1 / 100, I think.

Honeywell AD120

When Adding an AD120-Meter, add a Generic_Modbus_Meter

Use the following settings:

Modbus Address: xxx

Regester to: 000

Register to: 4 Byte Integer (Big Endian)

Set the xxx for the Modbus Address that was set with the software.

See Example of Default Setting 001 Defult 9600,EVEN,7,1  NOTE: Can be set to other Baud and Parity.

Next:

Go to Edit> Advanced Meter Settings

Change the Number of real time registers to read  from 0 to 1. And Submit

Now Change the settings to the following:

User Name______________Register_________________Format________________Scalar_________________Interpret As

2 byte int4 byte int (big endian)4 byte float4 byte int (little endian)PowerCOM8 byte int (big endian)8 byte int (little endian)8 byte int (Schneider)NoneE1E2F1F2F3F4SV1V2V3V1 AngleV2 AngleV3 AngleV4 AngleI1I2I3I4I1 AngleI2 AngleI3 AngleI4 Angle

Also set the meter to read every 30 min to have profile.
This Meter does not Log Profile and only logs Totals.

The results can be checked under Edit>Meter Totals
