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
