I do not think this has changed from a previous version. The difference might be due to the fact that I have instructed you to tweak these settings in the past already.

Yes, it can be changed programmatically:
- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ultiple%20Implementations.html .

If the program does not set it, it can be set from an "external" configuration file:
- kb.opclabs.com/Intrinsic_Component_Configuration
- kb.opclabs.com/Intrinsic_component_configuration_examples

Hi,

So what do you suggest?
Can it be done programmatically?

Not that we didn't have this problem in previous versions.

Thank you.

Michael

Yes it can.

Hi,

Thank you for your answer.
One question: if I will change to EnableNetApiClient = False, can it affect browsing other OPC DA servers?

Thank you.

Michael

Hello.

RS Linx OPC browsing is hopelessly broken.
Try to switch to the Native implementation (EnableNativeClient = True, EnableNetApiClient = False).

Hi,

We are getting this exception when trying to browse the RSLinx OPC server. When using Matrikon OPC Explorer, there is no problem.

I appreciate your answer.

Michael
