page describes how to make and run the Chads software. This page also descirbes how to set-up the AIDA database to fetch Channel Archive History PVs.
aidatest daDpChadsTest 1 2 3
Note: Test 1 requests data for HR81:CAV2:VACM//HIST.  It is assumed that the AIDA database is setup for that request going to dpChads. Test 2 prompts you for the PV and Time Range.
See the AIDA SQL Cheat sheet, section AIDA Directory Database Content Maintenance for an example of how you would teach AIDA to acquire History Data for a Channel Archiver PV which is of type DOUBLE (which they all are), and the AIDA Directory Service Database Document, for more information and the general principles.
Test Archiver History PVs
The following PVs were added to the Aida Directory Service to help test the reference edition of the Channel Archiver data provider:
So, these names will be found in the INSTANCE column of AIDA_NAMES, and the other directory service additions in order to support them, as described in the AIDA Directory Service Database Guide, have already been carried out.
The test program daDpChadsTest (described above) allows you to exercise
dpChads with these PV's.
