Link. To validate the download of Guarded Peer Link
templates, the GPL Checker and GPL Printer are used.
The GPL Checker uploads the Guarded Peer Link template
files from the Regent controller and re-converts the template
data into readable form in the GPL Echo File. The re-
converted GPL Echo Files are then printed using the GPL
Printer and compared by the application programmer to the
original template specification, thus providing a complete,
closed-loop validation of the template compilation and
download process.
GPL Checker also automatically checks the power up value
and time out action for each GPL variable.
Failure Modes and Effects Analysis
By using the Integrity Checker tools, the application
programmer can assure with a high degree of certainty that
faults in the creation, compilation and download of application
programs will be caught. Table 1 provides a brief Failure
Modes and Effects Analysis of this data path.
