24.3 Universal fault inputs (1…10)
Function block "Faults" has 10 universal fault inputs at its disposal. Any type of
analog or digital signal can be fed to these inputs.

Fault input 10 ---, N.X1, N.X2, ...
The following settings are possible for each fault message:
 Fault status signal delay.
Elapsed time until a pending fault generates a fault message
 Fault acknowledgement
 Impact of fault
 Fault priority
 Limit value "Fault on": Limit value from which the fault status message is
generated
 Limit value "Fault off": Limit value for the normal state

 If the upper and the lower limit of a measured value is to be monitored, the
signal must be fed to 2 fault inputs
 To monitor the lower limit, the operating line "Limit value fault on" is set below
"Limit value fault off". This generates a fault message when the measured value
is lower than the "Limit value fault on"
 The differential "Limit value fault on" and "Limit value fault off" represents the
hysteresis
 If data point "Limit value fault on" is set equal to "Limit value fault off", no fault
message is generated
