The class Instance and Attribute acts in the following way:
- 100 added to the parameter group = the value for the class.
- 100 added to the remaining parameter number = the value for the instance.
- 100 added to the array index of the parameter = the value for the attribute
Examples: (fictitious parameters)
- Parameter 0-01 [index 0] = Class 100; Instance 101; Attribute 100
- Parameter 1-00 [index 0] = Class 101; Instance 100; Attribute 100 - Parameter 2-59[index 0] = Class 102; Instance 159; Attribute 100
- Parameter 5-34[index 3] = Class 105; Instance 134; Attribute 103
- Parameter 6-54 [index 9] = Class 106; Instance 154; Attribute 109
- Parameter 10-01 [index 0] = Class 110; Instance 101; Attribute 100
All values in decimal.
