Description
The EPICS SNCSEQ module (aka "SNL Sequencer") is getting close to its end of life: Finite state machines are limited and don't scale to the size of modern EPICS installations. Also, SNCSEQ does not understand the PVAccess network protocol.
But: It is performant, robust and stable. Almost every site is using it.
A possible future of SNCSEQ would restrict it to running local state machines inside the IOC: A much lighter codebase without support for CA or PVA, directly working with the EPICS Process Database instead.
