Hello,

 

I'm trying to extract archive values using PIAPI's piar_getarcvaluesx function in C#. Everything worked fine except one PI point (float32) that has following values:
3.816796E+12
3.816797E+12
3.816794E+12

 

The return value of the method is -15010 (Number Too Big For PIvalue), but the values not even close to double.MaxValue.

 

Any ideas?

 

 

 

P.S.

 

PISDK allows to extract the values without errors, unfortunately the application is written in PIAPI.
