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

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
