Schnieder Meter 64-bit register from 16-bit Register

[Ian@GWTi]

Hi,

I am looking to generate a 64-bit register from individual 16 bit registers from Schnieder meters,  See attached info sheet.

We are having to read the meters from a different KNX device which can only read the 16-bit registers and do the conversion in the logic machine.  This will then display the total on a visual interface.

I would also like it to send the valve back to the KNX bus.

Any help would be much apricated.

Thanks

Which meter exactly do you need?

[Ian@GWTi]

We use the PM31 and PM51 Meters,


Just looking at the modbus commands.  I think i could i use modbus address 2700 instead of breaking down the 64bit 3204 address?
