Instance attribute definitions
Attribute 1 to
n
— Request input data set specific parameters
These attributes return the input data set specific data arrays.
Get Attribute Single
requests for a specific input data set only return the parameter information for the
requested data set.
Get Attribute All
requests return the entire data set.
The data set attributes, numbered from 1 to N, refer to each individual attribute of each
individual input data set. Each instance relates to a unique input data set and each input
data set has a unique attribute numbering scheme. The following tables reflect the attri-
bute definitions for each input data set.
Get All Data Set Attributes request
All data set information will be returned in integer (16 bit word) format. For byte data, the
first byte will be placed in the least significant or rightmost byte of the integer and the
second byte will be placed in the most significant or leftmost byte of the integer.
Example:
For an input data set, the data will be returned as follows:
– IntegerArray[0]: BBAAh
— AA = BYTE1; BB = BYTE2
– IntegerArray[1]: DDCCh
— CC = BYTE3; DD = BYTE4
– …
– IntegerArray[6]: NNMMh
— MM = BYTE13; NN = BYTE14
