REAL data types are not supported by the B&R CANIO Manager on SG3 CPUs. Therefore they can be accessed as UDINT data types in the corresponding
hardware description files.
The UDINT variable data content corresponds to REAL format (IEEE), so it is important to note that using a "Casting" command is not permitted!
Example for C syntax: memcpy(HartREAL_PV,HartUDINT_PV,4)
