In all probability, the underlying AIM*API is configured for 5000 tags. This is
controlled by the file (doing this by memory) /opt/aim/bin/aimapi.cfg. The
parameter of interest is maxobj. This is covered in the AIM*API manual.
You'll need to change the file. Stop your OPC client, stop your OPC server,
stop AIM*API, restart AIM*API, restart OPC server, restart OPC client. A reboot
is not required.

Subject: [foxboro] OPC problem for adding new points.
Dear All,
I am adding some points into OPC server; was unable to configure them
properly and came across the following situation:
- No. of Points added : 16
- Total OPC Points: 5200
- OPC Points Quality in Matrikon OPC Explorer
- GOOD: 5080 Tags
- Bad, not connected: 120 Tags (Including new tags)
I'm curious as why it is not adding new points properly.
Things I've Tried:
- Update rate for newly added tags: 10sec. Changed to 25Sec
- Update rate for all tags: changed to 60 Sec
- Deleted all the tags of OPC then reset the OPC service also rebooted
the AW
- Then added few new tags, but these are showing bad in Matrikon
explorer. But when adding the tags which was communicating good before are
still coming good in Matrikon; but when adding some other parameters of same
tags, they are showing 'Bad, not connected'.
- Checkpoint all CPs and Gateways.
- Executed Nodebus tests.
Details of our system:
- CP60 Quantity 4
- MG30 Quantity 5
- CPs and GWs are hosted by P79 AW V7.1.1
- OPC's AW IA Version 7.1.5
- AIM*API Version 5.5.0
- The OPC has unlimited points license.
Kindly suggest me the solution of this problem.
Regards,
Imran Waheed Butt
