620 series IEC 60870-5-103 Communication Protocol Manual

According to the IEC 60870-5-103 standard, the TypeID 4 value coding format is 32-bit floating point. Since most of the measurands in the relay are natively of this format, no rescaling of the analog values is needed. If the native value is an integer, then the relay automatically converts this into floating point for TypeID 4. The scaling factor, seen in the measurands table, does not affect TypeID 4 objects.
