The configuration of an event or alarm can be done either on the signal type or on
each instance. To define the event and alarm handling please go through the
following steps.
1. Select the device object for which alarm handling is required (either an
instance or an object type) e.g. Simple On Off Motor in the Object Type
Structure.
2. Create a new signal “Motor_tripped” representing the signal for which alarm
handling is required.
3. On the Alarm and Event configuration aspect of the signal, select
“is_an_event” and “log statuschanges on”. Click Apply.
The signal object has now been configured to generate an even when the value
changes to on.
To see an alarm for a specific area, select the alarm list aspect for that area.
Adding History Logging
The Log Configuration aspect is used to make an historic log of a value received
from the PLC. The log can be defined either on the signal instances, or on the signal
types.To define a log on a type (and by this for all instances), go to the Object Type
Structure and add a Log Configuration aspect to the Signal object, then go through
the following steps.
1. Open the aspect and select Add Property Log.
2. Select Property Value in the list, and then select the log template e.g. OPC
Single Log.
3. Click OK.
4. Click Apply.
An instance of the object type has to be created and connected to the PLC to
generate an alarm.
This log configuration will now be active on all instances for this signal object.
To create a log on an individual object add and configure a “Log Configuration”
aspect to an instance in the Control Structure.
