Figure 51: 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. The n/o contact switches off when the actual
value at I7 falls below the setpoint minus hysteresis.
