The PROFIBUS devices have been particularly dimensioned for the industrial requirements of hazardous areas of zone 1. They are used for the separation or generation of new segments, converting the RS485 typical line structure into an open and flexible tree structure. Downstream stations can be coupled to and de-coupled from the superior bus system in a non-reactive and break/short-circuit tolerant manner, even during running bus operation.The devices facilitate a duplication of the signal to realize a redundant connection to a master. The devices are available as PROFIBUS-DP and as PROFIBUS-IS (intrinsically safe).
