The S7 data types and formats should be taken from the manual titled
"Programming with STEP 7 V5.4" (in the Appendix "Data and parameter
types").ePS Network Services does not support times or real numbers here.
The S7 data type is also determined by means of the data width. If a word is
defined, the following byte is, therefore, included automatically and blocked for a
separate format. If a double word is defined, all 4 bytes are assigned as double
words. ePS Network Services checks the plausibility of the potential formats and
only permits correct configurations (e.g. data word 121 is not permitted).
