I have a question regarding the use of shell functions with in the IOC shell. There is a shell function from StreamDevice called streamReload that I am interested in using periodically like every 30 seconds. What is the preferred method,
if there are any, for doing so? Also, is there a potential way for calling that shell function within the SNL sequencer?
This is unusual as operating mode. The reload function is intended for development / rapid prototyping (testing a protocol change without rebooting the IOC). So - please be careful with respect to possible side effects: What happens if the protocol file gets corrupted, a typo is being introduced, the disk (or nfs) is down etc. How do you detect such a situation? How do you fix it? Needs testing.
Cheers, ~Ralph
