Communication Driver Alarms
Using the information in the topic, Communication Driver Log-Enabled Variables, you can create Alarm tags to warn operators of a loss in communication or a decrease in communication quality.
Reference Notes:
The alarm tag will use an expression as its trigger, where the expression refers to one of the log-enabled variables in the communication driver. It is recommended that you create the alarm tag as a child of the driver tag.
Example:
An alarm to warn of driver quality falling below 0.95.
Expression: [*Driver]\Quality
This expression assumes that the Alarm tag was created as the child of a driver. If the alarm cannot refer to a parent driver, substitute the full name of the driver tag for "*Driver".
Shown configured in an alarm tag:
