Supported data point types of the CP
Note
Plant Cloud in the operation center cannot process ARRAY
The Plant Cloud in the operation center does not support the ARRAY
data type. Transfers of
this data type are discarded by the operation center. Make sure that you take this into
account in the configuration of the data points.

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.
Compatible components of ARRAY are the following uniform S7 data types with a size
between 1 and 32 bytes:
● BYTE, CHAR (in total up to 64 times per block of data)
● INT (in total up to 32 times per block of data)
● DINT, UDINT (in total up to 16 times per block of data)
If the array is modified later, the data point must be recreated.
Time stamp in UTC format
Time stamps are transferred in UTC format (48 bits) and contain the time difference in
milliseconds since 01.01.1970.
