Echelon OpenLNS - Manual (Page 475)

OpenLNS Programmer's Reference 438
To run a self-test on an object where the result may take
more than 20 seconds to complete, follow these steps:
1. Request a self-test of the LonMarkObject by writing the
lcaLonMarkObjectRequestSelfTest (3) value to the
object’s Request property.
2. After the exception is raised, poll the SelfTestInProgress
property of the ObjectStatus object until it returns False.
3. Check the FailSelfTest property of the ObjectStatus
object to determine why the test failed.
Note: All devices that do not comply with version 3.0 or later
of the LonMark Application-Layer Interoperability Guidelines
do not support self-tests. Some devices that comply with
version 3.0 or later of the LonMark Application-Layer
Interoperability Guidelines may not support self-tests.
You can use the ReportMask property to determine if a device
supports self-tests. If you attempt to read this property and
perform a self-test on a device that does not support
self-tests, an exception will be thrown.
Availability Local, full, and lightweight clients.
