OSI Pi Driver
Note that AB FactoryTalk uses a re-badged version of OSI Pi as its historian - this is the correct driver to use for FactoryTalk applications
Information
Loads both live and historical point-data from the Wonderware eDNA historian.
| Driver Info | Detail |
|---|---|
| Driver Type: | Live and History |
| Platforms: | Windows Only |
Driver Settings
The driver has no options - all configuration is done via the eDNA API setup, or in the INI file located at C:\ProgramData\InStep\DNASRV.ini
Note that you may want to add some additional options to your eDNA configuration to improve live data performance.
If you have more than 1000 live points of data, you will need to increase the size of your point resolver cache in the eDNA API. To do this, add/edit the client section in your DNASRV.ini file.
[CLIENT] POINT_RESOLVE_CACHE_SIZE=<the number of points needed>
Point Settings
Points are given either as eDNA short IDs, eDNA extended IDs, or as CHaD point references, in the form of <instance path>.<attribute>.
