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)
● Int, UInt, Word (total of up to 32 per data block)
● DInt, UDInt, DWord (total of up to 16 per data block)
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.

Status IDs of data points
Status IDs of data points
Along with the value of a data point, status identifiers of the data point are transferred in
every frame. They can be evaluated by the communications partner.
