For the allocation and description of the data of the CM35, see the descrip-
tion of the particular operating mode.
Remember the following points which concern the assurance of data consis-
tency based on the programmable controller used.
SIMATIC S7 (central or distributed)
Only one single
load command (L PIW or L PID) can be used to read the
desired value.
This means that an actual value in double--word format must be read with
one double--word access (L PID). Use of two word accesses (L PIW) can
cause data inconsistency in this case.
SIMATIC S5 or standard DP master (distributed)
Only
word--accesses to even addresses
may be used to read--access the de-
sired value.

ing values in
