7-232
Parameterization of the DP slave 611U is divided into 2 steps:
In Step 1, DP slave 611U-specific parameter settings are made for:
S
PROFIBUS address
S
Number of axes and encoders (message frame type)
S
I/O addresses
S
Expanded message frame configuration (SW 2.2 and higher).
Step 1 should first be carried out for all DP slaves 611U required for the configu-
ration.
Step 2 includes parameterization of equidistant DP communication. Step 2 can
be carried out finally, for any DP slave 611U.
The settings made during the operational sequence above can be transferred to
all of the remaining DP slaves 611U using the matching function of SlaveOM.
Inserting a DP slave 611U into the configuration will open the dialog for parame-
terizing the PROFIBUS DP properties.
SlaveOM sets the PROFIBUS address to the next free PROFIBUS address
automatically.
The PROFIBUS address can generally be freely selected. It must, however,
match the PROFIBUS address set in the drive (e.g. with SimoCom U) (parame-
ter P0918).
Notice
The PROFIBUS address of DP slave 611U, which is set on the SlaveOM, must
match with the PROFIBUS address set in the drive:
No automatic adjustment takes place!
The following data must be identical.
1. SIMATIC S7 configuration of DP slave 611U
PROFIBUS address
2. SIMODRIVE 611 universal
Parameter P0918 (PROFIBUS node address.)
