4.4.5.3 Function of the Equal to comparison
Parameter display and parameter set for Equal to analog value comparator.

1: actual value at I8, multiplied with gain factor F2
2: setpoint plus hysteresis value
3: setpoint
4: setpoint minus hysteresis
The N/O contact switches on if the actual value at I8 (multiplied by F1)
reaches the configured setpoint value. If the actual value exceeds the
setpoint, the make contact switches off. The N/O contact switches on if the
actual value at I8 (multiplied by F1) reaches the configured setpoint value. If
the actual value falls below the setpoint value minus hysteresis, the N/O
contact switches off.

The values F2 +0 and OS +0 were not defined. No values are
used with a gain factor, and no offset is used. A gain factor of 8
is used with the analog value at I10. The hysteresis is adjusted
accordingly.
