Parameterizing Dp Slaves - Siemens SINUMERIK 840Di sl Commissioning Manual

PROFIBUS DP Communication
8.9 DP slave SINAMICS S120
Expanded message frame configuration
The "expanded message frame configuration" has been provided to transfer additional 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 extended message frame configuration is described in Section "Extended message
frame configuration/evaluation of internal drive variables" (Page 589).
8.9.3

Parameterizing DP slaves

The assignment of parameters to DP slave S120 is divided into 2 steps:
● Step 1
● Step 2
PROFIBUS address
Inserting a DP slave S120 into the configuration will open the dialog for assigning
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 S120 DP slave:
2. SINAMICS S120, CU320
288
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 configuration.
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 transferred to all of the
remaining DP slaves S120 using the matching function of SlaveOM.
