Notes:
1) Choose a format for the tag names that you will use for
GPL variables. For example, the last three characters of
each tag name (e.g. _R1, _R2, _R3 or _R4) were chosen to
indicate which Regent originates the variable to the GPL
network. This type of tag name format is not required but
it helps identify the GPL variables to system engineers
and other plant personnel.
2) A Regent might only output data to the GPL network. For
example, Regent 3 outputs three variables to the GPL
network. However, it doesn’t have any definitions for the
variables that are output by the other Regents. The GPL
data received from the other Regents will not be used by
Regent 3.
3) A Regent might only input data from the GPL network.
For example, Regent 4 doesn’t output any variables to the
GPL network. However, it has four variables defined that
will be input from the GPL data of the other Regents.
You should plan for the GPL configuration by making sure
that each Regent has an identical tag name defined (typically
in its shared variable definition) for every variable it will need
to receive from another Regent.
Initial and Final Values
When you configure variables in the I/O and shared variable
definition editors, you can configure an initial and final value
for each variable (except digital and analog inputs). These
