Bence,

Images do not come through on most Apache lists ( I didn’t get it for sure
). What version of nifi, what version of the processors are you using? What
is the name of the processor? We recently landed record based processors,
but I am not sure there has been a release with them yet.

Subject:  Re: Can't connect to OPC UA from NIFI

Hi Bence,

I wasn't involved with the Nifi processor, but remembering an email thread
on the mailing list. The format for OPCUA was a bit different.


*So to approach this and allow these "special" characters ('=',';') on the
variableAddress we proposed to use the following syntax:
'MaxCurrentImax'='ns=2;i=33'At the moment, we created a method
"parseAddressString()" whose idea is to detect whether the protocol
is OPCUA (or any other that could be included), to force the following
variable address syntax: 'varName1'='varAddress1';'varName2'='varAddress2'*

Hope this helps.

Ben
