The class instance and attribute act 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 (ctitious 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] =
