For the possible formats of the ARRAY data type, refer to the following section.
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)
Time stamps are transferred in UTC format (48 bits) and contain the time difference in
milliseconds since 01.01.1970.
