Don't forget that the IGNLM1/2 parameters are connectable/settable.
This of course means that the parameters may not necessarily have been
changed via the ICC/FoxCAE/IACC/IEE. You may need to take your feed
data from one or more sources such as 'iccprt' and 'getpars'.
Back in the mid nineties the first I/A system I worked on (then as a
customer) was for a batch plant (migrated from another suppliers
system). Due to the unreliability of the valve limit switches, ignoring
limits was quite a common operator action on both the I/A and the other
suppliers system. Way back then we put in a request for the capability
of the Process Summary Reporter to be enhanced to include the IGNLM1/2
parameters. But unfortunately the request fell by the way side.

Here's what David sent me off list, just in case someone else needs
this tool.
#cd /opt/fox/ciocfg/api
# iccprt -p -o /tmp/CPNAME.txt CPNAME
OK now we need to extract what you are interested in.
Use the awk script David posted earlier.
#cd /tmp
#awk -f Get_GDEV_Limits.awk CPNAME.txt > my_results.txt #more
my_results.txt

Nice, but you forgot to say what to feed to it and how to generate it.

Getpars is good and quick, but the initial question was are limits =3D3D
configured, and are they being ignored. The implication is you would =3D
=3D3D
only turn on the IGNLM1 if a limit switch was failing. So getpars =3D3D
isn't too helpful to see what is going on in this instance. (Unless =3D3D
we assume that any block with the IGNLM[1,2] set to true is a hit and =3D
=3D3D
then we would have to still get the DEVLM[1,2] if that is what we are =3D
=3D3D
trying to fix. You are fixing the bad limit switches right Ken?)
This awk script only took a couple of minutes to write and it gives a =3D
=3D3D
much better snapshot of what is configured. (But not what is =3D3D
happening, it's like quantum physics.)
I'm cutting this from a unix session so CR/LFs might be wonky.
BEGIN{
printf ("Block Name, Type, DEVLM1, IGNLM1, DEVLM2, IGNLM2 \n")
}
{
if ($1 =3D3D3D=3D3D3D "NAME") name =3D3D3D $3
if ($1 =3D3D3D=3D3D3D "TYPE") type =3D3D3D $3
if ($1 =3D3D3D=3D3D3D "DEVLM1") devlm1 =3D3D3D $3
if ($1 =3D3D3D=3D3D3D "DEVLM2") devlm2 =3D3D3D $3
if ($1 =3D3D3D=3D3D3D "IGNLM1") ignlm1 =3D3D3D $3
if ($1 =3D3D3D=3D3D3D "IGNLM2") ignlm2 =3D3D3D $3
if ($1 =3D3D3D=3D3D3D "END" && type =3D3D3D=3D3D3D "GDEV")
{
printf ("%-24s, %s, %24s, %s, %24s, =3D3D
%s\n",name,type,devlm1,ignlm1,devlm2,ignlm2)
}
}
There, wasn't that easy?

David
