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

A scaled integer (int16) is derived from the IEC 61850 data classes/attributes defined for integer values, that is, the common data classes dealing with either integer or enumeral values. The default scaling for the IEC 60870-5-104 value is 1, making it identical to the corresponding IEC 61850 value (CDC.attribute/attribute/ …).
