Alarm
Alarm when a counter value is reached
Instead of responding to the state of the inputs and outputs,
you can trigger an alarm when a counter state is reached. To
do this you must enter a value between 1 and 4.2 billion in the
Max Counter Value field. An alarm is issued when one of the
activated inputs reaches this counter value.
Counter and input patterns are mutually exclusive as alarm
conditions. As soon as you have entered a value in Max Counter
Value, the state of the inputs is no longer used as an alarm
condition, and only the counter state is monitored.
Alarm for load error
The outputs of the Web-IO 12+12 Digital have thermal overload
monitoring. If an overload is detected on an output, it is
immediately turned off. If no load is detected it works also.
Over- or underload can also be used as an alarm condition. To
do this, select Load Control under Config >> Device >> Alarm
>> Alarm1, System Trigger.

When an overload occurs, the corresponding output can
be enabled again after eliminating the overload by
opening Diag >> Report in the navigation tree and clicking on
the Cancel Report button.
Time-based alarm
Activating Interval Timer can allow the Web-IO to regularly issue
alarms at intervals specified under Interval regardless of the input
and output state.
