Configuring a PROFIBUS-DP Network with COM PROFIBUS

Before reading this topic, you should read and understand PROFIBUS Configuration. This topic only gives a specific example of doing one step of the configuration process. In addition, Siemens may, and probably will, change the steps taken here slightly with each version of COM PROFIBUS.

 

The following steps have been tested with COM PROFIBUS versions 3.0 and 3.3:

 

  1. Start COM PROFIBUS.

  2. If you are modifying an existing PROFIBUS-DP network, open your current configuration file.

  3. If you are creating a new PROFIBUS-DP network, you must create a new network and add a master device to the network.

  4. If it is not already in the database, add the GSD file to your configuration programs GSD database.

  5. Add and configure an RMC Motion Controller slave device to the network.

  6. You may wish to assign register addresses within the master at this time.
    This is optional for many masters, because it can be done in the master configuration software. In fact, at times it is not possible to edit the register addresses.

  7. Select the data word order.
    Because PROFIBUS-DP does not specify the word order for 32-bit values, we allow the order to be swapped. You will probably not know which is correct until later in the process. If you receive data over the PROFIBUS network, but the values are not what you expect or do not make sense, return to this step and try swapping the word order:

  8. Add any other RMC devices you want on the same network. To do this, repeat steps 5, 6 and 7.

  9. Save your configuration.

  10. Send the configuration to the master device. This step varies greatly depending on the type of master you use.
