Signal diagram of analog value comparator in Greater than/equal to mode
1: actual value at I7
2: setpoint plus hysteresis value
3: setpoint
4: setpoint minus hysteresis
The N/O contact switches if the actual value at I7 is equal to the setpoint
value. The N/O contact switches off when the actual value at I7 falls below
the setpoint minus hysteresis.
