Description
Analog input signal processing.
Defines the filter time constant for analogue input AI1.

-t/T
O = I × (1 - e
I = filter input (step)
O = filter output
t = time
T = filter time constant
Note: The signal is also filtered due to the signal interface
hardware (approximately 0.25 ms time constant). This cannot
be changed by any parameter.
Filter time constant.
Defines the maximum value for analogue input AI1. The input
type is selected with jumper J1 on the JCU Control Unit.
Maximum AI1 value.
Defines the minimum value for analogue input AI1. The input
type is selected with jumper J1 on the JCU Control Unit.
