SINUMERIK 840Di Manual (HBI) – 06.03 Edition
Notice
The message frame type of DP slave ADI4, which is set on the SlaveOM, must
match with the PROFIBUS address set on the NC.
No automatic adjustment takes place!
The following data must be identical.
1. SIMATIC S7 configuration DP slave ADI4
Message frame type (3)
2. SINUMERIK 840Di–NC
MD13060 DRIVE_TELEGRAM_TYP (3)
Dialog: DP Slave Properties
Tab: Configuration
Default: <Message Frame Type>
OK
A communication between NC and the individual axes of the DP slaves ADI4 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 ADI4 into a configuration.
The standard default of the NC machine data:
S
MD13050 DRIVE-LOGIC_ADDRESS[n], (logical drive address)
is described in Subsection 10.5.1, page 10-308.
Dialog: DP Slave Properties
Tab: Configuration
PROFIBUS partner, I/O addr.: <I/O address>
OK
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 ADI4 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 w272 for ADI4 DP slave I/O addresses.
