Update IOC with pushed data

[Dave Bracey via Tech-talk <tech-talk at aps.anl.gov>]

We would like data to travel through an IOC with as little latency as possible.  Can I use Event Scanning rather than Periodic to achieve this? 

 

At one point I tried having a data source use a User-Defined Event to trigger record processing, but I didn’t get it working at that time.

 

I’m assuming this is the idea behind I/O Interrupt Event triggering – the record is triggered to process on new I/O, and the Device or Driver handler reads the data from the data source.

 

We would want a software notification to trigger processing of a record.  Any advice what to pursue?
