Discrete Input Function Block

The figure below shows how measured values are processed within the Discrete Input
Function Block.

How it works
The Discrete Input Function Block allows you to control modifications to the output value
(PROFIBUS cyclic data):
• Select Inversion ON or OFF: when ON, the Primary Value from the Transducer Block, or a
simulation value given by the simulation switch, will be inverted.
• Select Failsafe behavior options: if the status of the Primary Value or Simulation Value is
bad, the fault logic can output either the last usable measured value (Mode 22 = LUv), a
given substitute value (0 or 1), or the last usable measure value with the status Bad,
sensor failure.
• Select one of 3 settings:
• The result is the output parameter (OUT).
