    8.1.1 General information The BPS 34 with MS 34 103/MS 34 105 is designed as a PROFIBUS device (PROFIBUS DP-V0 acc. to IEC 61784-1) with a baud rate of 12MBd. The functionality of the device is defined via parameter sets which are clustered in modules.
  • Page 34 Chapter 10.7 on Page 72. The BPS 34 can be used in combination with an MS 34 103/MS 34 105 to branch out the PROFIBUS network. The continuing network is connected via DP OUT.

    You can find the GSD file at www.leuze.com. This file stores all the data required for the operation of the BPS 34. This data consists of device parame- ters required for the operation of the BPS 34 and the definition of the control and status bits. If parameters are changed in the project tool, for example, these changes are stored in the project, not in the GSD file.

With the "delay error output" parameter, an integration error (corresponds to a missing position value) can be signaled immedi- ately or after the tolerance time has elapsed.
  • Page 59 Description The "service" function is used to reset the parameter set of the BPS 34 to default settings. This reset only occurs directly in the BPS 34. After the reset function has been activated, the device carries out a reset and is freshly configured on the PROFIBUS.
