Datapoint types
During the configuration of the user data to be transferred by the CP, each data point is
assigned a 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).
As of the firmware version named in the preface along with STEP 7Basic V14, the CP
supports the following data point types and data types.
The direction relates to the direction of transfer:
● "in": Monitoring direction:
● "out": Control direction
