I am using Cimplicity with MODBUS driver to gather data from a tank gauging system. I can read all the integer values, but when I try to read floating point numbers, I do not get any data in the point database.
Can someone please help?

 

Without more data, all I can suggest for now is to double check your setup parameters.

Floating point numbers are considered double precision and must be prefaced with 'D4'. So an address would be something like: 'D4xxxx'. Your integer holding registers are simply '4xxxx'. Floats should be 'D4xxxx'.
