Currently Logic can not read/write 64 bit integers ie VT_UI8 and VT_I8.

The largest granule file tag is an example of this (#HIS.Raw.Largest File). When viewed as a variable in FBD/ST these values will return zero.

A workaround for this is to have an OPC point reference the tag ie "#HIS.Raw.Largest File".

The Current Value of this point can then be used in a logic program if required. This example returns the file size in bytes (32 bytes per record).
