CHcValueStatus

• Base type Enumeration

This data type indicates the validity and sign of the data in associated object instances which represent the absolute value of a high capacity numeric quantity. Such an object may be represented with one or more object instances. An object of type CHcValueStatus MUST be defined within the same structure as the object(s) representing the high capacity absolute value. If the associated object instance(s) representing the high capacity absolute value could not be accessed during the sampling interval, and is therefore invalid, then the associated CHcValueStatus object will contain the value 'valueNotAvailable(1)'. If the associated object instance(s) representing the high capacity absolute value are valid and actual value of the sample is greater than or equal to zero, then the associated CHcValueStatus object will contain the value 'valuePositive(2)'. If the associated object instance(s) representing the high capacity absolute value are valid and the actual value of the sample is less than zero, then the associated CHcValueStatus object will contain the value 'valueNegative(3)'. The associated absolute value should be multiplied by -1 to obtain the true sample value.
