For configurations
M09
from 3 to 8, analogue input 1 is used as a digital input. The contact is considered closed if it is shortcir-
cuited at the analogue input. The contact is considered open if there is no connection.
Note:
If one or more digital and/or analogue inputs are configured with the same control functionality, then the input with the higher
priority is considered.
Input priority:
Digital input 1 (
DI1
)
-
Highest priority
