Datapoint types

During the configuration of the user data to be transferred by the CP, each data point is
assigned a protocol-specific data point type. The data point types supported by the CP along
with the compatible S7 data types are listed below. They are grouped according to format
(memory requirements).
The direction relates to the direction of transfer (monitoring direction = "in", control direction
= "out").
