Hello Jan,
What is your terminator?
I tried to reproduce your problem but everything seems to work.
BTW: There are some other ways:
1. Use 3-state mbbi and %{off|on |INTERLOCK} format.
2. Use default value assignment (relatively new feature):
%?... does not fail on mismatch but results in 0. (or "" for string
formats).
in "get ch\$1 status\r\r\n = %?{off|on }%(\$2){INTERLOCK|}";
If the device sends "INTERLOCK", %?{off|on } results in 0 (Off) and
%(\$2){INTERLOCK|} in 1 (INTERLOCK)
If the device sends "off" or "on ", %(\$2){INTERLOCK|} results in 1 (Ok).

Hi all,
I have a device that sends a response on command
"on/off" (requested value) or "INTERLOCK").
I use a @mismatch exception handler and redirection to record in
order to catch this "INTERLOCK" string. After that I turn on or off the
LED widget
(Interlocked or Non-Interlocked). When I started IOC it gave me a buffer
overflow.
Buffer overflow is appeared after adding arg: (\$2).
DB and proto file are following:
DB:
# requested value laser state
record(bi, "$(device):StatEnable")
{
field(DESC, "Laser Enabled")
field(DTYP, "stream")
field(INP, "@fibotecLtbis.proto
get_enable($(channel),$(device):StatEnableInterlock) $(port)")
field(SCAN, "1 second")
field(ZNAM, "Off")
field(ONAM, "On")
field(PINI,"YES")
}
#makro
#channel=1
#device=name:ch1
#
#Catching INTERLOCK message
record(bi, "$(device):StatEnableInterlock")
{
field(DESC, "Laser Enabled")
field(ZNAM, "INTERLOCK")
field(ONAM, "Ok")
field(VAL, "1")
field(PINI,"YES")
}
Proto file:
get_enable { out "get ch\$1 status"; in "get ch\$1 status\r\r\n =
%{off|on } ";
@mismatch {in "get ch\$1 status\r\r\n%(\$2){INTERLOCK}";}}
Thanks Jan
