Effects of the value 0 (zero) on various typical classes
•
Sending process typicals
(Bin04B_S, Ana04W_S, Cnt01D_S/Cnt04D_S, Dat12D_S, Dat256D_S)
Programming 0 is useful, if PartnerNo = 0 was programmed for the
previous parameter. If the"PartnerObjectNo" is missing, there must be a list
on the partner CPU from which the missing object number can be
recognized (see FC-ListGenerator).
If the partner is an ST7cc control center specifying the "PartnerObjectNo"
for this block can be omitted because in ST7cc there are no DBs as target
objects. ST7cc decodes its data solely based on the source address in the
data frame.

Receiving operator typicals
(Bin04B_R, Ana04W_R, Cnt01D_R/Cnt04D_R, Dat12D_R, Dat256D_R)
The value 0 is not permitted!
If the programming is incorrect (< 1 or > 32000), an error message is
entered in the diagnostic buffer (event ID B102). The CPU does not
change to STOP. The block is then no longer processed, however, until the
error in the programming has been corrected.
If the CPU receives data for the object programmed here, there is a check
to establish whether the source object number in the data frame is identical
to the "PartnerObjectNo" programmed here. If they are different, the
received information is discarded. An error message is entered in the
diagnostic buffer (event ID B131).
