PDS and small floating point numbers

I am having an issue with the PDS driver in Cimplicity 8.2 SIM24. I have updated to PDS 3.6.9 without solving the problem.

I am reading symbolic values from an Rx7i PLC. When a floating point number becomes very small (for example 2.45677e-45) the point will go invalid in Cimplicity. Once the value in the PLC changes to a resonable number the point values begin updating again in Cimplicity.
