Can any one know how to change it ?
i am using v3.5.9.0

Hi HeroLin

Please see this commend:
The problem is if the runtime starts before you have an valid IP address which
is usually the case the OPCUA Server does not reasign/change the address.
This leads to problems on startup (runtime works OPCUA not)
You could workaround this by a later start of the runtime (init Sleep with 20s)
If you have a port problem you could configure the port in /etc/CODESYSControl.cfg (and even which nic you want to use for OPCUA)

[CmpOPCUA]
NetworkAdapter=eth0
NetworkPort=4841

Hope this can help you.
