Please be aware that oBIX creates an additional load on R2 stations. Tests indicate the following:
- A VxWorks (controller) R2 station with 40 percent idle time and 500,000 resources consumed can accommodate 1000
AX Obix proxies in a watch.
- A VxWorks (controller) R2 station with 30 percent idle time and 500,000 resources consumed can accommodate 500
AX Obix proxies in a watch.
Inspect idle time by pointing a browser to: http://ipAddress:3011/system/spy
Determine resource count by pointing a browser to: http://ipAddress/prism/resources
Please note that the above results depend on how the
AX client is reading the values, that is, is it polling all of the points all of the time, or only some, etc. “Your results
may vary.” In addition, the watch interval (adjusted on the
AX client side) plays a role in the loading of an R2 station.
For related details, see “Pre-integration R2 station changes” on page 2-3, and “Client polling timing” on page 2-15.
