The AIx filt gain inputs determine a filtering time for each input as follows:
The AIx mode outputs show whether the corresponding input is voltage (0) or current
(1). The voltage/current selection is made using the hardware switches on the FIO-11.
Inputs Analogue input filter gain selection (AI1 filt gain … AI3 filt gain): INT
Minimum value of input signal (AI1 Min … AI3 Min): REAL (> -11 V or -22 mA)
Maximum value of input signal (AI1 Max … AI3 Max): REAL (< 11 V or 22 mA)
Minimum value of scaled output signal (AI1 Min scale … AI3 Min scale): REAL
Maximum value of scaled output signal (AI1 Max scale … AI3 Max scale): REAL
Outputs Analogue input mode (voltage or current) (AI1 mode … AI3 mode): Boolean
Value of analogue input (AI1 … AI3): REAL
Scaled value of analogue input (AI1 scaled … AI3 scaled): REAL
Error output (Error): DINT (0 = No error; 1 = Application program memory full)
