How to read the 64bit modbus data in AC800M controller from Mass Flow Meter.
One of our project we supplied PM864 controller along CI853 for Modbus interfacing.
But at the time of interfacing I faced a problem. The cumulative value of Flow is available in four 16bit register (i. e. R1, R2, R3 & R4 four integer value). I can't understand how to combine the four integer value in a single value.
Kindly some boby help me to resolve the same.
It's very critical data for customer.

I dont think it is possible to combine four 16bits register into one 64bit double floating value.
But you can create graphic elements in PG2 or VB to display value, but only for display purpose.
