I/O addresses

Precondition
For communication between the controller and the individual axes of an ADI4 DP slave, it is
necessary that the setpoint and the actual value of an axis have the same I/O addresses.
HW Config takes this requirement into account automatically when an ADI4 DP slave is inserted
in the configuration.
Inserting I/O addresses
1. In the "DP Slave Properties" dialog box, select the "Configuration" tab.
2. Under PROFIBUS partner, I/O addr. enter: <I/O address>.
3. Click on "OK".
Note
• The setpoint and actual value of an axis must have the same I/O address.
• If an ADI4 DP slave is inserted into an S7 project using a copy operation, e.g. from another
• To avoid access conflicts between PROFIBUS DP drives and I/O modules, the following

Error codes in Gx_XIST2
Meaning Possible causes/description
Encoder sum The encoder signal levels are too low, faulty (inadequate shielding) or cable
error breakage monitoring has been tripped.
Zero mark A fluctuation in the measured rotor position has arisen between two encoder
monitoring zero marks (encoder pulses may be lost).
I address (actual value) = O address (setpoint)
S7 project, then HW config directly assigns the I/O addresses. This may have the
consequence that an axis is assigned different I/O addresses for setpoint and actual
values. In this case, the I/O addresses must be corrected manually.
values must be used for I/O addresses for the ADI4 DP slave:
– NCU 7x0.2 DP: ≥ 272
– NCU 7x0.3 DP: ≥ 1024
