Uploading the Configuration
The PROFIBUS can be scanned by ADS read for new devices during operation:
ADS-Read parameters | Meaning |
|---|---|
Net-ID | Net-ID of the master (see the device's ADS tab) |
Port | 200 |
IndexGroup | 0xzzyyF830 (yy = station address, zz = 0: in Beckhoff devices, tables 0, 1 and 9 are read, zz = 0x80: Beckhoff devices return the same information as devices from other manufacturers) |
IndexOffset | 0 |
Length | 1538 |
Data | Configuration data of the slave |
If the IndexGroup indicates that, for Beckhoff devices, tables 0, 1 and 9 are to be read, then the following data is supplied, provided the device is a Beckhoff device:
Offset | Description |
|---|---|
0 -1 | 0 |
2 -513 | Table 0. Amongst the information contained here is the precise coupler type and the firmware version. |
514 - 1025 | Table 9 (includes the coupler number and the terminal numbers) |
1026 - 1537 | Table 1 (only relevant for bus controllers. The assignment of the terminals is part of the information contained here) |
If the device is from another manufacturer, or if the IndexGroup indicates that Beckhoff devices are to behave in exactly the same way as devices from other manufacturers, then the following information is returned in the ADS read response:
Offset | Description |
|---|---|
0 -1 | 1 |
2 - 7 | DP diagnostic data bytes 0-5 (see Slave Diagnostics) |
8 - 251 | DP configuration data (CfgData) |
