EtherCAT communication EL6731-00x0
Fig. 136: Flow chart: Sequence of the configuration of the EL6731-0010 with start SDOs
Following a power-on, the EL6731-0010 is in the INIT state and has no DP configuration. The EL6731-0010
is not active on the PROFIBUS.
DP slave configuration
The DP configuration is carried out via SDO download in the PREOP state. The objects to be loaded must
be transmitted either with Complete Access or with consistency nesting (first set SubIndex 0 to 0, then write
SubIndex 1-n, then set SubIndex 0 to n). Care should thereby be taken to always start with object 0xF800
[} 170]. The DP CfgData are to be transferred with object 0x8002 [} 170]. After the receipt of object 0x8000,
the EL6731-0010 is active on the PROFIBUS (FDL only, no DP). The EL6731-0010 supports automatic baud
rate search, therefore no baud rate need be configured.
