Map for numerical data types

The following rules explain how data types are handled for the containers in which the AVEVA Historian Client controls can be run.

In C# or .NET environments:

• Byte = 8 bits

• Int = 32 bits

• Long = 64 bits

• Short = 16 bits

In C++ or IDL environments ( versions prior to ActiveFactory 9.0 software):

• Byte = 8 bits

• Int = 32 bits

• Long = 32 bits

• Short = 16 bits

The size of long in the C++/IDL environment is the same as the size of int in C#.

In the InTouch HMI software, an integer value is stored in 32 bits.
