4.4.4 Accessing parameter data
The following figure shows how the parameter data are mapped on the SDO objects:
Parameter data EtherCAT-Slot

Subindex
0x3102
SM 031 AI 2x 12Bit
01h, 02h
0x3103
FM 050 1x32Bit
01h ... 0Fh
For module parameterization SDO transfer takes place. Here the EtherCAT-Slot is
addressed via
index
. Via
subindexes
the corresponding parameters may be accessed.
The allocation of the subindexes may be found in the description of the corresponding
System SLIO module.

Modules with no interrupt capability or whose diagnostic interrupt is de-
activated can not send an interrupt message on an error in parameteriza-
tion. Possible parameterization errors may be detected by means of a
diagnostic request after the parameterization.
