POS_ALERT_HI
User defined high position threshold
that when FINAL_VALUE is more
positive will trigger a position high
alert. The alert is generated via the
standard Field Diagnostic mechanism
as defined in References
(FOUNDATION™ Specification,
Function Block Application Process
Part 1 – FF-890, Rev FS 1.10) and
(FOUNDATION™ Specification,

In the FF standard dictionary revision lower than the revision 3.80, the user may see this parameter with a different label: “Signal Action”. This is
a defect in the dictionary fixed in the revision 3.80 but old host systems may still use an old revision and therefore show the wrong parameter name,
giving the impression that there are two parameters with the same name (SIGNAL_ACTION)
