The function of the LEDs is described under
Chapter 1.7.5.1.9 “State LEDs” on page 970
.
Unused input channels can be left open-circuited, because they are of low resistance.
To avoid error messages through unused analog input channels in measuring range 4...20 mA,
these channels should be configured as "Not used".
Connection of Active-type Analog Sensors (Voltage) with no Electrically Isolated Power Supply to the
Analog Inputs
The following figure shows the connection of active-type analog sensors (voltage) with no elec-
trically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to AI3
in the same way.
