IndexOffset Description
0x00-0xFF This will send a DPV1-Write 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 (see section DPV1 [} 46]).
0x00-0xFF This will send a DPV1-Write to the appropriate, configured DPV1
slave via a Class 2 connection; the DPV1 slot number
corresponds to the 0x100 IndexGroup, the DPV1 index
corresponds to the IndexOffset (see section DPV1 [} 46]).
0x00 With this, a DPV1 Abort is sent to the appropriate configured
DPV1 slave via a class 2 connection; the abort parameters are
included in the data (-> section DPV1 [} 46]).
0x00-0xFF This will transmit a PKW-Write 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]).
This will send FDL-Write for Siemens AG interfacing to the
appropriate configured FDL station (only FC310x, see
documentation for FC310x section S5-FDL).
This will send a SetSlaveAddress command to a configured DP
slave, whereby the DP slave must be configured with the new
station address; the old station address must be entered at BYTE
offset 0 of the ADS-Write data. Furthermore, the Ident no. of the
slave must be contained under BYTE offset 1 and 2, and BYTE
offset 3 must contain information as to whether the slave may be
modified later (0) or not (not equal 0). Altogether, 4 bytes of ADS-
Write data will therefore have to be sent.
IndexOffset Description
0x00-0xFF This will send a DPV1-Data_Transport to the appropriate,
configured DPV1 slave via a Class 2 connection; the DPV1 slot
number corresponds to the 0x100 IndexGroup, the DPV1 index
corresponds to the IndexOffset (see section DPV1 [} 46]).
0x00 With this, a DPV1 Initiate is sent to the appropriate configured
DPV1 slave via a class 2 connection; the initiate parameters are
included in the data (-> section DPV1 [} 46]).
