Experimental Physics and Industrial Control System

If you use a seq record for that purpose, you can even shuffle around
(numerical) values and introduce delays.
Nice beast for all kinds of small "state transitions" where a few things
have to be done unconditionally in a certain order.

My really simple solution was to insert a single fanout record with
PINI=1 that forced all of the necessary records to process in the
correct order. That fanout record served no other purpose, which kept
the system logically clean. Ultimately, there was a whole tree of fanout
records, but they were all controlled by the one at the root of the
tree.

Subject: Record Initialization
Is it possible to control the order in which epics records
are initialized when the IOC starts up?
I am working on an IOC for a device and I would like to reset
this device. I have an output record which writes a number
to the device at init time (PINI=YES), which resets it. In
order that my scheme works, this record needs to be
initialized before any other record. I am using streamdevice
with asyn. I am tracing all IO and I see that the
initialization order is arbitrary.
Any help would be appreciated,
Zen
