Profibus DP – CBF-B1/CBFF-B1 Burner Control Box
vor00161
Device specific parameters must be considered during PROFIBUS-DP system configuration. In order to simplify this proc-
ess, CBF-B1/CBFF-B1 control boxes are supplied with a data file containing these parameters (GSD). The file format is
standardized and recognizable by other Profibus devices (masters/slaves). The bus interface will remain operable (online)
even if the CBF-/CBFF-B1 is turned off (stand-by mode) The setting of the Profibus addresses can be done by using the ad-
dress selector switches within the Profibus control box (Picture 2).
