1. Configure the PROFIBUS master and start it, even when not all configured slaves have been connected.

  2. Connect the ibaBM-DP device to the PROFIBUS. Both connections “X40: Bus 0” and "X41: can be used. This way, the slaves can be simulated by two different bus lines.

  3. Switch on ibaBM-DP.

    While booting, ibaBM-DP is searching for “missing” slaves. These are all slaves, which are requested by the PROFIBUS master, but do not respond, as they are not present on the bus. These physically missing slaves are simulated by ibaBM-DP.

    From now on, all displayed bus errors should disappear on the PROFIBUS master. Since ibaBM-DP simulates all missing slaves, the PROFIBUS master detects the configured slaves as being existent and valid.

  4. Start the simulation program and establish a TCP/IP connection to ibaBM-DP.

    The following settings apply to the TCP/IP connection:

    • The simulation program is the “active” communication partner. Here, you have to enter the IP address (or device name) and the port number of ibaBM-DP. You find the IP address on the Info page in the web interface. The port number is “999”.

    • You can define a “send” and “receive” telegram for each slave to be simulated. The receive telegram contains the data, the master sends to the slave (outputs). Within the send telegram, you can simulate the data the slave sends to the master (inputs).

      For detailed information on the telegram layouts see chapter Telegram layout.
