Hi!

This is not a server problem because happen only with opclabs engine. I have tested other client and works perfectly.

Have you tested it?

so if you write same value with kepware opc ua driver Subscription tag doesn t works anymore with opclabs engine (Tested with your opc ua demo also) and I need to restart kepware server

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?

No problem is opclabs engine because with kepware quickclient works,iconics works,and other engine works. Only with opclabs crash. Have you tested it?

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
