EL6731 44 Version: 2.8
IndexGroup for addressing of a configured PROFIBUS device (port 0x1000-0x107E)
IndexGroup
(Lo-Word) IndexGroup
(Hi-Word) IndexOffset Description
0x00-0xFF 0x00 0x00-0xFF This will send a DPV1-Read to the appropriate, configured DPV1
slave via a Class 1 connection; the DPV1 slot number
corresponds to the IndexGroup, the DPV1 index corresponds to
the IndexOffset. If the ADS-Read is answered without error (error
code = 0), the data will contain the read DPV1 data (see section
DPV1 [
}
46] )
0x100-0x1F
F 0x00 0x00-0xFF This will send a DPV1-Read to the appropriate, configured DPV1
slave via a Class 2 connection; the DPV1 slot number
corresponds to the IndexGroup - 0x100, the DPV1 index
corresponds to the IndexOffset. If the ADS-Read is answered
without error (error code = 0), the data will contain the read DPV1
data (see section
DPV1 [
}
46] )
0x0000 -
0xFFF 0x10000000
-
0xF0000000 0x00-0xFF This will transmit a PKW-Read to the appropriate, configured
PROFIDRIVE slave; the parameter number (PNU) is contained in
the Low WORD of the IndexGroup, the sub-index for access to an
array is in the IndexOffset, the addressed axis is in bits 28-31 of
the IndexGroup (for a 1-axis unit, this must be 1), the PKW
compatibility can be adjusted in bits 26, 27 (unfortunately, not all
PROFIDRIVE slaves are compatible, see section
PKW-Interface
[
}
49] ).
0 0x01000000 0 This will send FDL-Read for Siemens AG interfacing to the
appropriate configured FDL station (only FC310x, see
documentation for FC310x section S5-FDL).
ADS Write
An overview of the IndexGroups/IndexOffsets supported by the FC310x/EL6731 during ADS-Write is
provided below.
IndexGroup for local addressing of the FC310x/EL6731 (port 200)
IndexGroup
(Lo-Word) IndexGroup
(Hi-Word) IndexOffset Description
0xF100 0x00 0 -2 This will reset the equidistant diagnostic data (IndexOffset = 0),
the Repeat counters (IndexOffset = 1) or the NoAnswer counters
(IndexOffset = 2) of the FC310x/EL6731.
