In SW 2.2 and higher, ”expanded message frame configuration” has been pro-
vided to transfer drive data to the NC in the cyclic PROFIBUS message frame in
addition to the process data (PDA) for the selected standard message frame
type (102 to 107).
The expanded message frame configuration is described in Section 18.2, Page
18-501.
8.10.3 Parameterizing DP slaves
Parameterization of the DP slave 611U is divided into 2 steps:
S Step 1
In Step 1, DP slave 611U–specific parameter settings are made for:
– PROFIBUS address
– Number of axes and encoders (message frame type)
– I/O addresses
– Expanded message frame configuration (SW 2.2 and higher)
Step 1 should first be carried out for all DP slaves 611U required for the con-
figuration.
S Step 2
Step 2 includes parameterization of isochronous DP communication. Step 2
can be carried out finally, for any DP slave 611U.
The settings made during the operational sequence above can be trans-
ferred 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:
There is no automatic adjustment!
The following data must agree:
1. SIMATIC configuration of DP slave 611U
PROFIBUS address
2. SIMODRIVE 611 universal
