Is the question concerning the number of channels that can be monitored and archived (which as Leo said, is very large, into the many thousands), or are you asking specifically about ‘simultaneous monitoring’, grabbing many channels at exactly the same point
in time?
EPICS can acquire and archive many, many channels, but each channel will be acquired at -slightly- different time. As far as I know, you can’t do something like a triggered, simultaneous acquisition of a number of channels (say, 50…100) at precisely the
same point in time without specific hardware capable of performing that function. There are many devices (both commercially available, and custom manufactured) that can be interfaced to the EPICS system that can do that function, and provide that information
to EPICS.
Later-
