Hey Mathias,
Thanks for the feedback. It actually turned out to be a problem with the INP fields, which I was able to figure out based on your example.

Subject: RE: fsmRecord Initial State
It's been a while, but I've worked with fsmRecord and have had no such problem.
IOW, the transitions worked as advertised, right out the box.
It's not clear to me whether
field(TST0, "1")
is a valid transition or not.
It may be worth performing a "real" test for your TST0 condition, such as "pvX > 0."
Start your IOC with pvX = 0, then set it to 1.0 and see if your record transitions then.
Before trying any "real" work, though, make sure to check .STAT to see if you don't have a trivial problem with your record.
Cheers -Mathias
----
the stuff below works for me...
#----------------------------
# Initial FSM State
# checks for auto/manual
record(fsm, "$(dipole):fsm:init") {
field(INP, "@$(dipole):fsm;Init")
field(SCAN, "2 second") # no hurry here
field(VAL, "YES")
field(TST0, "$(dipole):auto.VAL PP")
field(TRN0, "$(dipole):fsm:matching PP")
#
field(TST1, "$(dipole):auto.VAL PP")
field(INV1, "1") #
field(TRN1, "$(dipole):fsm:manual PP") # either auto is true or not...
# nothing else to do
}
#----------------------------
# manual state
#
record(fsm, "$(dipole):fsm:manual") {
field(INP, "@$(dipole):fsm;Manual")
field(SCAN, "5 second")
field(TST0, "$(dipole):auto")
field(TRN0, "$(dipole):fsm:matching PP") # transition to 'matching'
# nothing else to do
}
