Re: [foxboro] PLB ladder running in FBM? Plus, disappearing files

Mike,

We have migrated (upgraded?) from Unix to Windows, but if my memory
serves me correctly the PLB Files used by Display Manager for the Detail
Displays are located in: usr\plc\CMP_NAME\PLB_NAME\ and FoxView in
usr\plcfv\CMP_NAME\PLB_NAME\*.fdf  There should be several files 1, 2
,etc corresponding to the ladder logic pages in the detail display.
Check if these exist.  If not I think they are re-created when the
ladder is compiled and downloaded.  Maybe try just compiling if you
don't want to download and see if that does the trick.

As far as verifying what you actually have in the FBM, I am not sure if
there is any upload / compare feature for ladders.  You may want to
verify the source code and then just download again when possible to be
sure.  Do any of the Foxboro guys have a suggestion?  We use ladders in
our FBMs with IACC, and this would be good trick to know.

Hope this is of some help,

Subject: [foxboro] PLB ladder running in FBM? Plus, disappearing files

System: old-school nodebus at v7.1.1 running AW51G boxes and CP30s.

Situation: I have a 100-series FBM whose .p file disappeared from the
/opt/fox/ciocfg/<compound_name> directory.  I don't know how that
happened.
I can't see the ladder from the PLB's detail display, and of course the
ladder appears blank when looking at it through the ICC.  I found a
saveall
from about 3 weeks ago that turned out to have the .p file in it, and I
copied that file to /opt/fox/ciocfg/<compound_name>, so now I can see
the
ladder properly in the ICC but not on the detail display.  The FBM looks
fine in Sys Management.  The PLB's detail display shows some IFLs and
OFLs
lit up and other not, and there's no cyan/smurfing present on either the
detail display or process display elements linked to this PLB.  The PLB
detail display's faceplate says "Logic = On-Line".

The .i, .r and .s files for sequence blocks in the same directory are
also
missing but  I will burn that bridge when I get to it.

Question #1: how do I know if the FBM is actually executing a "real"
copy
of the ladder and not just an empty ladder?  I know I could compile and
re-insert my restored ladder via ICC but the process is online and I
don't
want to disrupt the timing and one-shot functions of the ladder if it's
already running OK in the FBM.  Rebooting the Matrix usually causes
problems.

Question #2: how can PLB and sequence files just disappear from
/opt/fox/ciocfg/<compound_name> but the blocks be running OK per the
process and detail displays?
