Overview of bus architecture
If more than one operation unit is required for a sensor, the bus
architecture specified above must be used. Up to two sensors
and three D‑ISC100s can be installed within this architecture.
Each of the two sensors can therefore be equipped with one on-
site operation unit (Db and Dc). (Da) acts as the central control
unit for the two sensors here, and as the interface to the evalu-
ation system. (Sb) and the associated (Dc) are optional; (Sb)
