Hi Ralph
Answer one: Don't do that.
Answer two: We are working on a solution to use the data buffer of the timing
system for real-time communication. We will need such a fast channel for our
FEL. At the moment, the data flow is only one way. We hope that "upstream"
communication will be possible soon (depending how busy Jukka is).

Hello!
What would be the smartest way to implement fast cross-IOC loops that
are high-priority?
Problem: The CA server tasks on the target IOC are low priority (for
good reasons, I know!), so that - even with a fast synchronous device
support -
any stupid slow-and-low record processing on that IOC will introduce
delays, which leads to jitter or multiple CA updates before the target
record gets processed.
Oh, yes: "fast" would be something below 200Hz.
Any hints welcome...
