Dynamic Text in Alarm Expression Message
Is it is possible to provide the dynamic text in Alarm Expression Message.
Example: "Tank Level HH > 65%" where 65 is dynamic value.
As these HH values are changed from the PLC system, so that they want to know the current HH value along with Alarm Message.
AFAIK the message texts (coming/going) of an Alarm Expression are constant.
If possible, stick to true alarms "made in a PLC" and delivered to System 800xA from an OPC AE server.
Expressions are less reliable and come with a higher price (continuous data feed to the Soft Alarm service).
