4.5 Analog Input Block (AI 1...4)
The following tables list the Analog Input Block parameters in alphabetical order.
It describes characteristics of the measurement values obtained from the Transducer Block in a
user defined way and to deliver it to the control system. There are also some parameters in the
Analog Input Block, that can be configured to get a measurement value quality as desired by the
user.
The following tables contain short parameter description, factory settings (Initial Value (IV)) and
possible settings.
