Hi All,

I am working on OPC server development.
I have the following doubt:
what are all the ways that the OPC UA client can write/update the OPC UA server variable value ?
As per my knowledge, through OPC server’s Write() function, the client can update the value.

Any other ways are there ?

[I am facing the following issue:
Third party vendor’s UA client is connected to my OPC server and creates the subscription for the variable.
It is trying to update the value in some way, but it is not calling Write() function]

Thanks & Regards,
Sundararajan
