: Configuring data points using substitute object
groups
The initial data point types of the following object groups can be configured using the
substitute object groups listed above:
● 10 [2]
● 11 [1, 2]
● 21 [1, 2, 5, 6]
● 23 [1, 2, 5, 6]
● 40 [1, 2, 3]
● 42 [1, 2, 4, 5, 6, 7, 8]
To configure the DNP3 CP, use the specified substitute object group.
