Figure 50: Signal diagram of analog value comparator in Equal to
mode
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. If the
actual value exceeds the setpoint, the n/o contact switches
off. The n/o contact switches on if the actual value at I8
(multiplied by F1) reaches the configured setpoint. If the
actual value falls below the setpoint minus hysteresis, the
n/o contact switches off.
