To use this feature you have to install:

pip install --user docx

pip install --user docxtpl

To run the converter

$>cd $PYGEN/test

$>python icd_converter.py -f <your ICD file (xlsx format)>

An experimental simulation OPC-UA server written in python can be also generatedwith this version of pyGen. Arrays are not supported at present, then to play with it use ICD that do not include arrays.

$>opcua-client

Insert for example:"opc.tcp://127.0.0.1:52523/OPCUA/hwSimulator" in the input box on top left of the client and click on the "Connect button". You can play with the servers nodes now.
