Dear list,
Situation:
Version 8.2 system with terminal server, some CP270's, ATS and AW70 with OPC
server software (german I/Aconnect, very nice!).
The terminal server is the host for a number of Industrial field PC's in the
compressor building. We do NOT want to install the OPC server on the
terminal server.
For this reason we have the AW70 with the I/A_connect OPC server installed.
This seems to work very well.
The initial idea was to also install the OPC client software on the AW70 but
we did not realise the fact that this OPC client software is not a native
windows application and the configuration tools for it ALSO need to run
under Exceed !!!
We were able to install the client software on the AW70 but when starting
the application we soon discovered that the Foxboro pre-installed Exceed was
not co-operating!
There seem to be 2 paths on the AW70 which holds exceed dll's and
executables and although the path env var. contains the hummingbird\exceed .
etc. path it looks like the client wants to execute (in this case) the
localcon.exe from the apps32 directory ?!
Question: does the above mentioned set-up have any change of success
(installing a 3th party application which also needs exceed on a AW70) ??
If so, could somebody knowledgeable give me some tips (Ron, I hope you read
this!).
Installing the client application onto a non-I/A PC, with exceed 9.0
installed (needed only for the OPC client) and connecting to the AW70 OPC
server works o.k.
So we do have this option as an alternative but I would not like to give up
on the AW-only solution just yet! The MTBF of the complete set-up will be
less with 2 PC's in 'series'.
The reason we use the (german) I/A_connect OPC server software is because
this supports SSC.
Indeed, this seems to work very nice!
Kind regards and thanks in advance for any advise,
(I do not agree with the statement: free advise is worth what you paid for
it. I have seen problems solved on this list for which we pay a substantial
yearly fee. I will also add that I feel our maintenance contract is really
worth the money (as a late response to an earlier posting)).
