Because DP slaves 611U can be assigned both to the NC and to the PLC,
check system functions SFC 14 and SFC 15 when writing data to see
whether the drive belongs to the writing component. If this is not the case,
the data access is denied.
The overview example shows the interrelations or interdependencies when con-
figuring the PROFIBUS DP communication between the components:
