FC310x as master
FC3101 and FC3102 28 Version: 3.0
3.6 ADS (acyclic communication)
3.6.1 ADS Interface
All acyclic data are transmitted to or from the FC310x via ADS-Read, ADS-Write or ADS-Write-Control. The
FC310x has its own Net-ID and supports the following ports:
Port Description
200 This addresses the FC310x itself, i.e. data that reside locally on the FC310x, and for
which usually no additional bus access is required
0x1000 - 0x107E This addresses a connected PROFIBUS device, with the address calculated from
port-0x1000; this always involves a bus access
ADS-Read
An overview of the IndexGroups/IndexOffsets supported by the FC310x during ADS-Read is provided below.
IndexGroup for local FC310x addressing (port 200)
Index-
Group (Lo-
Word) IndexGroup
(Hi-Word) IndexOffset Description
0xF100 0x00 BYTE offset
within the data This reads the diagnostic data from the FC310x. If the ADS-Read
is answered without error (error code = 0), the data will contain
the diagnostic data of the FC310x described in the
Master
Diagnostics [
}
20] chapter. The FC310x will reset the FC310x
DiagFlag. It will be set again, if the FC310x diagnostic data
change again.
0xF181 0x00-0x7E BYTE offset
within the data This will read the diagnostic data of a configured DP slave. The
station address is calculated from the IndexGroup(Hi-Word). If the
ADS Read is answered without error (error code = 0), the data will
contain the diagnostic data of a configured DP slave described in
the
Slave diagnostics [
}
23] chapter.
0xF830 0x8000-0x80
7E always 0 This enables detection of the DP slaves present at the
PROFIBUS, independent of whether they were configured or not.
The station address is calculated from IndexGroup(Hi-
Word)-0x8000. If the ADS-Read is answered without error (error
code = 0), the corresponding DP slave has answered correctly.
The data contain the Ident no. of the slave (BYTE offset 0-1) and
the read CfgData (from BYTE offset 2) (see chapter
Upload
Configuration [
}
34] ).
0xF840 0 BYTE offset
within the data This will read the firmware version and the station address of the
FC310x. If the ADS-Read is answered without error (error code =
0), the data will contain the firmware version (BYTE offset 0-1)
and the station address of the FC310x (BYTE offset 2).
