Hello Again,

i made i few more tests and the Problem is that Writemultiplevalues does not come back.

Tests with ReadMultipleValues without sendig are ok now, but if i activate Multiplewrite i have the problem that multiwrite does not come back when i plug the cable.


So my mainprogramm, that´s want to copy variables to the senderthread cannot access function Versand.add of the Senderthread and so the whole program freezes.


Kind regards
Dina

Hello, that sounds good.

It would be very helpful if you can send me the link to the beta.
Thank you

The default OperationTimeout is 2 minutes. If the method does not return after that, it is likely an issue of QuickOPC itself. We have recently fixed such an issue; however the fix will be only available i the upcoming version (2018.1), scheduled for release most likely in February.

If you are interested I can send you a private link to test the Beta version of it.
(Note: with Delphi, you will have to re-import the type libraries, as they have changed).

Best regards

Hello, I use Version 2017-2 with Delphi XE6 and Twincat 3.1 OPCUA Server

Sometimes when i switch Twincat to config mode ReadMultipleValues never comes back.
Normale i get an Error with every node i try to read like BadDeviceFailure or Timeout but sometimes the functions never comes back.

I have set FastestKeepaliveInterval to 30000 and FastestlifetimeInterval to 50000 with no result.

Is there an timeout that i can configure ?

What can i do?

regards

Dina
