SINUMERIK 840Di Manual (HBI) – 06.03 Edition
Notice
The message frame type of DP slave 611U, which is set on the SlaveOM, must
match with the PROFIBUS address set on the NC and the drive:
No automatic adjustment takes place!
The following data must be identical.
1. SIMATIC S7 configuration DP slave 611U
Message frame type
2. SINUMERIK 840Di-NC
MD13060 DRIVE_TELEGRAM_TYP
3. SIMODRIVE 611 universal
Parameter P0922 (PROFIBUS message frame type selection).

in each case in Section: Communication on PROFIBUS DP.
A communication between NC and the individual axes of the DP slaves 611U in
the SINUMERIK 840Di can only take place if the I/O addresses for setpoint and
actual value of an axis are the same.
This prerequisite is taken into account by SlaveOM automatically when inserting
a DP slave 611U into a configuration.
Notice
S
The I/O addresses for set and actual values of an axis must be the same.
I/O address actual value = = I/O address setpoint
If a DP slave 611U is inserted into an S7 project due to a copying process
(e.g. from another S7 project), the I/O addresses are assigned exclusively
under the control of “HW Config”.
This may have the consequence that one axis are assigned different I/O
addresses for set and actual values. In this case, the I/O addresses must
be corrected manually.
S
To avoid access conflicts between PROFIBUS DP drives and I/O modules,
you need to set values
w
