Function
DB10.DBB121
or indiv. data
element
The S7 data types and formats should be taken from the manual titled "Program-
ming with STEP 7 V5.4" (in the Appendix "Data and parameter types").ePS Net-
work 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 de-
fined, 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).
The checkback signals in an individual DB behave according. However, 8 bytes are
available. In addition, 4 bytes before and after the 8 bytes must be assigned identi-
fiers that are evaluated for write authorization.
