We are using CIMIO versio 4.9.7 and the 'ciofoxapi' version is 3.0.2.
A version 3.0.3 ciofoxapi was released to fix but now I'm not sure it'll
help us see below.
Here is some dialog between us and Aspen support (Matrikon):
""
HJB:
For which versions of the API does this apply to? 4.2.6 and 4.2.7?
SUPORT:
This problem applies to both versions of the API. The problem is the same
in that when we open the set in the code using scopen() there are some tags
reported as bad (but only for discretes). The error code returned from
scopen() is 26 and means "Object(s) not found" in the API manual.
The interface then continues to read the tags. The ones with the initial
problem should report an appropriate error after the read but for some
reason the read operation marks the tags as good and returns zero for the
value. We found that every tag not updating were the ones with error 26
when the set was opened. We cannot know why the tags are bad when the set
was opened as this is a Foxboro issue, but the work around will ensure that
the bad status is reported on these tags so they can be looked at in the
Fox system.
HJB:
It may be that the initial scopen() call mistakenly flags the tags as bad
and the bread() call then flags them (correctly) as good but enters a
value of 0. The discrete tags that display this problem are in fact 'ok'
on the DCS side, in fact do exist and should return a value. It may not
help us if the these tags are now always flagged bad.
SUPPORT:
Simply passing a bad quality for the tags is not the complete solution,
only a way of identifying a bigger issue with the API. The other customer
with the same issue has contacted Foxboro with the results of our testing
and should be receiving feedback shortly. I will keep you in the loop and
let you know when we get a response.

We are using FoxAPI 4.2.7 on a v. 6.5 AW51E, and haven't had any problems
with analog or discrete tags with IP.21. What version of all the IP.21
stuff are you running?
