Applies to:

PcVue version 7.10c.
In general if a project is used with a later version of PcVue it will be automatically converted to that version. Occasionally it may be necessary to make manual modifications.
Summary:

An example of the use of the multi-trend archive facility. The same variable is recorded in three separate archive units using different criteria.

  • On-change in a proprietary format archive unit.
  • With a 20 second filter in a proprietary format archive unit. (Variable only recorded once every 20 seconds IF it has changed.)
  • On-change in a free format archive unit.

One mimic contains a trend display with buttons that allow the user to switch between two archive units to display all the data, or the data sampled every 20 seconds.

A second mimic allows the user to display the data recorded in the free format archive units in either Wordpad or Excel.
