ADS Interface
All acyclic data are transmitted to or from the FC310x/EL6731 via ADS-Read, ADS-Write or ADS-Write-Control. The FC310x/EL6731 has its own Net ID and supports the following ports:
Port | Description |
---|---|
200 | Addresses the FC310x/EL6731 itself, i.e. data stored locally on the FC310x/EL6731, 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/EL6731 during ADS-Read is provided below.
IndexGroup for local addressing of the FC310x/EL6731 (port 200)
IndexGroup (Lo-Word) | IndexGroup (Hi-Word) | IndexOffset | Description | |
---|---|---|---|---|
FC310x | EL6731 | |||
0xF100 | 0x00 | BYTE offset within the data | This is used to read the diagnostic data of the FC310x/EL6731. If the ADS-Read is answered without error (error code = 0), the data will contain the diagnostic data of the FC310x/EL6731 described in section Master Diagnostics. The FC310x/EL6731 resets its DiagFlag, which is set again when the diagnostic data of the FC310x/EL6731 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 section Slave-Diagnose. | |
0xF830 | 0x8000-0x807E | 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 section Upload Configuration). | |
0xF840 | 0 | 0 | This is used to read the firmware version and station address of the FC310x/EL6731. 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/EL6731 (BYTE offset 2). | This is used to read the firmware version and station address of the FC310x/EL6731. If the ADS-Read is answered without error (error code = 0), the data will contain a contant (BYTE-Offset 0-1) and the station address of the EL6731 (BYTE-Offset 2). |
Change of the PROFIBUS station address via ADSWRITE (only EL6731 and EL6731-0010)
If the station address is set with this command, it is saved in the flash ROM of the terminal.
In this case, a designated station address via the Init commands (index 0x8000) is ignored.
After restoring the default parameters with index 0x1010, the address in index 0x8000:01 (for PROFIBUS Master: 0xF800:01) is accepted again.
Note: to receive a new address, the terminal has set through the INIT state to OP state again.

IndexGroup (Lo-Word) | IndexGroup (Hi-Word) | IndexOffset | Länge (in Byte) | Description |
---|---|---|---|---|
0xF480 | 0x00 | 0 -2 | 4 | Data[0] 0x45 |

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) |
0x100-0x1FF | 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) |
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). |
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. |

0x100-0x1FF | 0x00 | 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). |
0x400 | 0x00 | 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). |
0x0000 - 0xFFFF | 0x10000000 - 0xF0000000 | 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). |
0 | 0x01000000 | 0 | This will send FDL-Write for Siemens AG interfacing to the appropriate configured FDL station (only FC310x, see documentation for FC310x section S5-FDL). |
0 | 0x02000000 | 0 | 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. |
ADS-ReadWrite

IndexGroup for addressing of a configured PROFIBUS device (port 0x1000-0x107E)
IndexGroup (Lo-Word) | IndexGroup (Hi-Word) | IndexOffset | Description |
---|---|---|---|
0x100-0x1FF | 0x00 | 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). |
0x200 | 0x00 | 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). |
