Creating a TwinCAT PC file
DEFAULT CONFIG
DEFAULT-CONFIG contains the PROFIBUS data from the address %IB1000 input and %QB1000. The data length depends on the number of configured PROFIBUS data. A maximum of 244 bytes of input data and 244 bytes of output data can be parameterized. No further settings are required for this configuration type.
Inserting the BX3100 in a PROFIBUS master via the System Manager
Select your PROFIBUS master PC card in the System Manager and right-click on your PROFIBUS master card. The PROFIBUS devices will then be offered for selection, among them a BX3100. Select this and confirm with OK.
Opening an existing BX file
If you wish to work with the DEFAULT-CONFIG, interrupt the process at this point (see Creating PROFIBUS data in DEFAULT-CONFIG). Otherwise select your configured BX file. If no such file exists, you have to create one (Creating a BX file). Once you have selected your BX file, all required PROFIBUS data are copied automatically into your project from this file. You now have to create a link to your task and set the PROFIBUS address. The configuration can then be saved and the TwinCAT system started.
Creating PROFIBUS data in DEFAULT-CONFIG
- The PROFIBUS data can now be created. Various variables are available:
- Integer 8 bit
- Integer 16 bit
- Integer 32 bit
- Unsigned 8 bit
- Unsigned 16 bit
- Unsigned 32 bit
- FLOAT 32 bit
They have to match the variable types currently projected in the BX.
Data sizes from 1 byte to 64 words are available.
ADS Communication has to be selected for preparing the configuration. If the configuration data are to be transferred via the fieldbus, data communication has to be active, i.e. the BX must be in active data exchange with the higher-level controller.
