Parameterizing Dp Slaves - Siemens SINUMERIK 840Di sl Commissioning Manual

PROFIBUS DP Communication
8.10 DP slave SIMODRIVE drives
Expanded message frame configuration
In SW 2.2 and higher, "expanded message frame configuration" has been provided 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 extended message frame configuration is described in Section "Extended message
frame configuration/evaluation of internal drive variables" (Page 589).
8.10.3

Parameterizing DP slaves

Parameterization of the DP slave 611U is divided into 2 steps:
● Step 1
● Step 2
PROFIBUS address
Inserting a DP slave 611U into the configuration will open the dialog for parameterizing 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) (parameter 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 611U DP slave
2. SIMODRIVE 611 universal
298
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 configuration.
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 transferred to all of the
remaining DP slaves 611U using the matching function of SlaveOM.
