4.10.3 Datapoint types
Configure the user data to be transferred from the CPU that is referenced via PLC tags of
the CPU on the CP as data points.
The data point types supported by the CP along with the compatible S7 data types are listed
below for the various telecontrol protocols.
The direction relates to the direction of transfer:
● "in": Monitoring direction:
● "out": Control direction
Note
Effect of the change of arrays for data points
If an array is modified later, the data point must be recreated.
Data point types of the "TeleControl Basic" protocol

For the possible formats of the ARRAY data type, refer to the following section.
Block of data (ARRAY)
With the ARRAY data type, contiguous memory areas up to a size of 64 bytes can be
transferred. The following S7 data types are compatible components of ARRAY:
● Byte, USInt (total of up to 64 per data block)
● Char (total of up to 64 per data block) - CP as of firmware version 2.1.77
