9 OneOfN Analog Input Function Block
The figure below shows the basic design of the analog input function block.
The following attributes are supported:

Provides access to the selected parameter instances via the function block para-
meter interface. The channel instance number starts with 1. The selector deter-
mines which function/transducer block parameter set is mapped into the "OneOfN
Analog Input Function Block" or "OneOfN Vacuum Gauge Transducer Block" ad-
dress space.
Selects the PV of the function block instance which will be provided to the master
class 1 using the MS0 cyclic data exchange mechanism. The channel instance
number starts with 1. The selector defines the Analog Sensor Function Block
Instance which Process Value is used as output using cyclic data exchange
→  15).
