SSC600 and SSC600 SW IEC 60870-5-104 Communication Protocol Manual

The short floating-point type (float32) is derived from the IEC 61850 data classes/ attributes defined for measurand values. The default scaling for the IEC 60870-5-104 value is 1, making it identical to the corresponding IEC 61850 measurand value (CDC.attribute/attribute/ …).
