I do not understand your report good enough.

Originally, you wrote that "subscribe go in bad" and "i don t have anymore values".
That would most likely indicate a problem in the server.

Later you started writing about "crash". What do you mean? A specific error box/message from the app? If so, please provide details (minimum: what is the error text).

Regards

Configure 2 kepware servers with opcua client driver with float tags and write same value 2 times with your opcua demo application. So why I need contact kepware if your apps crash?

Hi!

I have problem to write same value. Subscription go bad forever.
I have 2 Kepware Server.
Remote Kepware server use Modbus (for example 192.168.1.1)
Insert float tag read/write and use simulate device( tag name float1)
Local Kepware(192.168.1.50) use opc ua Client driver (Gateway ) to connect with remote server.
So configure it with opc ua client driver to connect with remote tag(float1)
open your Easyopc ua demo and connect to local kepware server(192.168.1.50) with tag (Float1)
subscribe Float1
write value for example 10.1
works
write value for example 10.2
works
write value for example 10.3
works
write again 10.3
subscribe go in bad and i don t have anymore values

so if you write different values works but if you write same value subscribe crash

opclabs version 2017.1 kepware versione 5.15
