I have used PAR blocks to do this in the past.
Thank you for this tip. Looks like it should solve this issue.
Extract from manual on configuration:
Use the Database Dynamo Configuration Utility (BTKCFG.exe) to add the Persistent Array (PAR) to iFIX. After iFIX is restarted, you will then be able to add blocks of these types in the iFIX Database Manager.
1. Double-click the Btkcfg.exe file to launch the Database Dynamo Configuration Utility. By default, this file is located in the iFIX install folder, C:\Program Files\Proficy\Proficy iFIX.
2. In the Available Database Dynamos list, select BTK_PAR.dll and click Add
3. On the File menu, click Save.
4. Restart iFIX. After iFIX restarts, you will then be able to add the blocks in the above table within the iFIX Database Manager
It is also possible to add PAR via command line:
BTKCFG /ABTK_PAR
