20. Can I use FPMs to modify the SmartServer’s built-in applications (e.g., Alarm Generator,
Scheduler)?
No, you can’t modify the SmartServer’s built-in functions, but you can access the Built-in
applications’ data points.
21. Can the FPM module directly access data points of SmartServer built-in Applications (e.g.,
Alarm Notifier)?
Yes, you can use the List(), Read(), and Write() methods to access NVs that are external to your FPM.
However, these methods significantly impact the performance of the Smart Server. It is recommended
that you access the data points on the SmartServer by connecting them to data points in an FPM
application with L
ON W ORKS and Web connections.
Note: If the SmartServer is operating in LNS Auto or LNS Manual mode, you can use L ON W ORKS
and Web connections. If the SmartServer is operating in Standalone mode, you can only use Web
connections.
22. Can the FPMs call or access other SmartServer applications such as an Alarm Generator?
No, an FPM can not call any of the SmartServer’s built-in applications. To access the data points in
the SmartServer’s built-in applications, you can use the FPM List(), Read(), Write() methods;
LonWorks connections; and Web connections.
23. Can an FPM dynamically create data points in an LNS network database?
No. Only the data points that you declare in the UFPT used by your FPM are added to the LNS
network database.
24. Can I use Changeable Types for my FPM NVs?
