Input I1
7347
This input can be used as follows:

digital low-side input for positive sensor signal

digital high-side input for negative sensor signal

analogue input
 measurement resolution 8 bits, accuracy

5 % full scale, cannot be calibrated
 0...10 V
 0...32 V
 0...20 mA
 ratiometric
Sensors with diagnostic capabilities to NAMUR can be evaluated.
If the input is used as an analogue channel, it can be diagnosed at any time via the steady analogue
value in the system variables ANALOG00.
If the analogue input is configured for current measurement, the device switches to the safe voltage
measuring range (0...32 V DC) if the final value (21.7 mA) is exceeded and the respective error bit in
the flag byte ERROR_CURRENT_Ix is set. If the value is again below the limit value, the input
automatically switches back to the current measuring range.
Configuration via function block

Info
When using the analogue input functions the diagnosis does not have to be activated via the system
variable I0x_MODE.
The inputs are configured via the application software. INPUT ( → page 326 ) configures the operating
mode of the selected analogue channel via the function input MODE (

example below).
