Dirk,
Re: W59- duplicate output channel
This is not an error message. It is a warning message that attempts to alert
the user that the potential exists that the same output channel is/maybe in
use by multiple blocks.
This change was made in response to a problem originally reported by
CAR1002747. The CAR stated that there were several cases of damaged
equipment in the field caused by multiple PLB blocks writing to the same
contact output.
This issue was taken to the Safety Committee. The committee concluded that
it was NOT a safety issue, since the user documentation warned against the
possibility of incorrect behavior when multiple PLB blocks are connected to
the same FBM.
That said, the Safety Committee also strongly recommended that a warning
message be added to the I/A product in a future release. In response to this
recommendation, this was done.
I haven't searched the user notes for the QF that you have, but it should
mention the warning message. Would you mind checking for me?
Please let me know if you have any other questions.

Subject: [foxboro] CP60 new image problem
Does anyone outhere have FBM41 & 42 on CP60's? We do, and have never
experienced problems with it, now we re-imaged the CP60, using QF1005621,
and all of our PLB's which are on FBM41 & 42 are showing in green in the
select. Reason for this seems to be the fact that if you use FBM41 with
extender FBM42, both plb's use the same iomid, the FBM42 doesn't have it's
own iomid. The plb's are working ok, but it's not possible to change the
config in the icc, we keep getting error W59- duplicate output channel. So
we cannot save the changes. Therefore we cannot edit any of the PLB's
concerned. Is there any solution without changing back to the old image?
Seems Foxboro forgot about the Extender FBM42 in their new image.... One way
to edit the plb's seems to be to save the ladder logic in the library,
delete the plb and create it again, type in all the ifl's, including the
corrections/new ifl's and then copy the logic from the library, edit and
save. Any suggestions from the Foxboro guru's?
