PCo Kepware demonstration

PCo 2.1

Kepware EX 5.6

We have installed PCo 2.1 and the Kepware EX 5.6 and we are getting an error when we try to execute our example agent.  We tried to keep it simple by leaving the defaults to the OPC DA 3.0 connection, but we are getting this error.  Not exactly sure what needs to be set up or if some of the prerequisite software has failed to completely install properly.  Any advice is greatly appreciated.

Greg,

The COM error you get indicates you have version issues or registry issues.

Your installation may be of order and incomplete.  Uninstall PCo and KepwareEx, then install the following in the order shown:

1. Make sure the target PC has the latest .Net Framework V3.5 SP1 and patches
2. OPC Core Components Redistributable (X86)  Version 3.00.105.1 from: http://www.opcfoundation.org.  You will have to login or create a login with the org to download the files
3. KepServerEx 5.6.
4. PCo 2.1 (prefer you install 2.1.6.2 from SMP).

Hope this helps...

I have done everything you asked and I still get the same error.  Is there anything else I can try?

Questions: 

1.  can you browse/add tags with the PCo OPC Agent Instance?

2.  can you browse/manipulate tags with Kepware OPCQuickClient?

3. which OS are you running on?

Open Control Panel -->Administrative Tools-->Services and make sure that the Net.tcp port sharing service is set to either Manual or Automatic Start, and start it if not running.

Are you running ManagementConsole As Administrator (even if you are logged in with an Admin account)?

Did you assign a Service user name to run the Agent Instance, or leave the default .\localsystem account?

Already Started and Manual

Are you running ManagementConsole As Administrator (even if you are logged in with an Admin account)?

I already  run as Administrator

Did you assign a Service user name to run the Agent Instance, or leave the default .\localsystem account?

I am using the default for now.

It doesn't seem to be a PCo issue because it connects to the OPC Kepware source.  I am thinking it has to do with a security issue or a driver issue outside of PCo.

If you cannot browse and Add Subscription Items Tags for the Agent Instance, you are not connecting to the OPC Server.  What error(s) do you get when you try to browse from the Subcription items tab for the Agent Instance?

Does the server have Microsoft.Net Framework 4.0 installed?

Any additional error detail in the Event Viewer application logs?

I have 3.5 framework installed as the guide suggested and there is no other error detail that is different than what I provided.

[former_member196557 · Accepted solution]

Greg,

I you are certain the .Net Framewok 4.0 is not installed, then I am out of suggestions.  At this point I think you will need to log a CSS ticket to get this resolved.  Sorry I couldn't solve your problem.

- Steve

[Former Member · Accepted solution]

Should the server have 4.0 or am I correct in having 3,5?  Not exactly sure from your previous response.  I will log a ticket ASAP.  Thanks for your help.

[former_member196557 · Accepted solution]

PCo is not compatible with .Net Framework 4.0.  If it is installed you will need to perform the following:

1. Uninstall PCo
2. Uninstall Frameworks 4.0
3. Uninstall Framewokrs 4.0 client profile
4. reboot
5. install PCo

it there are no ohter software products installed on the server other than what you listed for SAP products, then uninstalling the 4.0 Framework should not cause any issues.

ok, I don't have 4.0 installed.  I was just asking to see if you were asking me to install it.

[Former Member · Accepted solution]

Discovered that 4.0 was indeed installed.  I removed it and it now works fine.  Thanks!!
