I have to transform my “read only driver” to “read write driver”.
That is, I wrote a driver, that reads variable from a custom tcp protocol, and puts the
values inside the node map “((DataNode) node).setValue(inVar.getValue());” I used the
weather sample as model, so I extends NodeMapDriver and on connect method I refresh the
Now the variables have to be ReadWrite so, when the user change the value on HMI I have to
write the change on tcp.
The question is, can the driver be notified when the user change a variable value?
