Appendix C: EPM 7700 - Special
Considerations
EPM 7700 Tags Subject to Deactivation by Tabular Data Screen Wizard
This appendix lists the EPM 7700 tags which may be activated or deactivated by the
EPM 7700 Tabular Data Screen wizard. This information is of use for developers
creating their own wizards to access the EPM 7700’s data. If you wish to use a tag in
a custom wizard you are developing, check this table to see if it is subject to
deactivation by the Tabular Data Screen wizard. If it is, you may wish to create a
duplicate tag with a unique name to access the same register. Otherwise, it is possible
that the tag may be deactivated by the Tabular Data Screen wizard, and the data will
be unavailable for use by your custom wizard.
NOTE: It is important to keep in mind that tags which may be deactivated by the
Tabular Data Screen Wizard will not work properly with InTouch’s trending
features.
NOTE: _Anlg or _Msg indicate Internal Tags for display use; _GWY indicates I/O
Tags which talk to GE77GTWY. All others tags talk to ION_LINK
