S.Hariharan,
In the aim api config tool, there are settings for users and security. I have
found when using OPC for OIS, we have to add a user that is that AW name and
set the security level for that user. For our OIS tags that are now using OPC,
we have had to append \\AWNAME\ to the C:B.P.
Check around in the api config tool, which is on the historian box.

Subject: [foxboro] AIM Historian - OPC Tunneller - Honeywell server - Data
Write Access problem
Dear Sir,
We are using matrikon OPC tunneller to transfer data from Foxboro Historian
server to Honeywell PIMS server.
We are facing issue in some tags. The value of these tags are healthy in
Foxboro historian and also in OPC tunneller but not in Honeywell server.
M/s Honeywell has reported that the confidence level of these tags are < 100%
and from their side the system is ok.
M/s Matrikon has reported that there is no restriction is Tunneller and it has
to be checked in Foxboro Historian.
While monitoring these tags in Matrikon OPC explorer, we observed these
problematic tags are having only Read Access and No write Access and further we
noticed that these tags are from one particular control Processor (CP).
Kindly suggest us how to enable the write option for these tags.
Thanks in advance.
With regards,
S.Hariharan
