For the format of the time stamp, see the following section.
For these data point types, create a data block with an array of precisely 2 bool.
With these data point types, contiguous memory areas up to a size of 32 bits can be transferred. Only the S7 Bool data
Time stamps are transferred according to the IEC specification in the "CP56Time2a" format.
Note that in the frames only the first 3 bytes for milliseconds and minutes are transferred.
