than 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 reaches the
setpoint. The n/o contact switches off when the actual value
at I7 falls below the setpoint minus hysteresis.
Example: Analog value comparator as two-step
controller
If, for example, the temperature goes below a value, A1
switches on the output Q1 with the enable input I5. If the
temperature exceeds the set value, A2 will switch off. If
there is no enable signal, output Q1 will always be switched
off by I5.

The values F1 +0, F2 +0 and OS +0 were not defined.
No values are used with a gain factor, and no offset is
