Thanks everyone for the great response, including all those sent to me personally.  To summarize those sent directly to me, they mirror what’s been indicated in this forum; the sequencer is indeed alive and well and used in a variety of settings at many (most?) EPICS sites.

But to answer your question Yong (and similar ones asked directly!) this comment about the sequencer came up in a small internal meeting with some people who are quite focused on very specific EPICS-related work that doesn’t require the sequencer.  SLAC has many hundreds of IOCs that do use the sequencer, so it’s great that EPICS as a toolkit can support a broad spectrum of users.

 

 

 

This topic is becoming so hot that I cannot help jumping in. I cannot imagine a facility (not a simple lab setup) using EPICS without using Sequencer. Doug, is that meeting at SLAC just internal?

At a recent meeting at SLAC, it was suggested that the EPICS Sequencer and its State Notation Language has become obsolete.  Are any sites other than SLAC still using this?  I assume so, but please let me know directly if your organization is using it, and I can summarize later.
