The ”expanded message frame configuration” has been provided to transfer
additional drive data to the NC in the cyclic PROFIBUS message frame in addi-
tion 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.
8.9.3 Parameterizing DP slaves
The assignment of parameters to DP slave S120 is divided into 2 steps:
S Step 1
In Step 1, DP slave S120–specific parameter settings are made for:
– PROFIBUS address
– Device version
– PROFIBUS message frame
– I/O addresses
– Expanded message frame configuration
Step 1 should first be carried out for all DP slaves S120 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 S120.
The settings made during the operational sequence above can be trans-
ferred to all of the remaining DP slaves S120 using the matching function of
SlaveOM.
Inserting a DP slave S120 into the configuration will open the dialog for assign-
ing parameters for PROFIBUS DP properties.
The PROFIBUS address is automatically set to the next free PROFIBUS
address.
The PROFIBUS address can generally be freely selected. It must, however,
match the PROFIBUS address set in the drive Control Unit (parameter P0918).
Notice
The PROFIBUS address of DP slave S120, which is set using HW Config,
must match the PROFIBUS address set in the drive:
There is no automatic adjustment!
The following data must agree:
1. SIMATIC configuration of DP slave S120
PROFIBUS address
2. SINAMICS S120, CU320
