STOP_LO_POS
1 - User defined low limit for valve
position that when reached will set a
stop lo position limit bit. 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, Function Block

In the FF standard dictionary revision lower than the revision 3.80, the user may see two parameters using the label: “Signal Action”. This is a
defect in the standard dictionary fixed in the revision 3.80. The parameter with the wrong label is the parameter RATED_TRAVEL.
ld host systems may still use an old revision of the dictionary and therefore show the wrong parameter name, giving the impression that there are
two parameters with the same name (SIGNAL_ACTION). It’s not difficult to pick the right SIGNAL_ACTION parameter because the SIGNAL
ACTION has only two options available.
