To use an analog input as additional digital input, you must interconnect the corresponding
status parameter r0722.11 or r0722.12 with a binector input of your choice.
You may operate the analog input as a digital input with 10 V or with 24 V.
NOTICE
Defective analog input due to overcurrent
If the analog input switch is set to "Current input" (I), a 10 V or 24 V voltage source results in
an overcurrent at the analog input. An overcurrent condition destroys the analog input.
● If you use an analog input as a digital input, then you must set the analog input switch to
"Voltage" (U).
