Computer Gateway User Manual 4-40 5/96

4.5.1

Use information: "Point name index" must = 0

"Parameter name index" is used to identify a specific parameter

array element. When used with nonarray parameters, this field

must = 0.

The order and number of points for each data type is significant (to

the CG for processing of Store Data messages and to the ACP for

the processing of Get Data Return messages) because the number

of data words for each point varies with data type.

For history requests, "order of data types" = (0, 1, 2, 5) and

"number of points of each type" = total number of history points

identified.
