<NEWS - 01/07/21>



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.



Before to use it you need to install some libraries:



———Python OPCUA support libraries —-

the ACS environment  must be active

library needed by Qt

from root /sudo 

yum install libxcb

yum install xcb-util-wm

yum install xcb-util-image

yum install xcb-util-keysyms

yum install xcb-util-renderutil



from user account:

Install pyQT

 pip3 install --user PyQt5

 pip3 install --user pyqtgraph



Install python opcua https://github.com/FreeOpcUa/python-opcua



 pip3 install --user opcua

 pip3 install --user opcua-client



The documentation on python opcua is here:

https://github.com/FreeOpcUa/python-opcua



--------Simulation server generation----------

$>cd $PYGEN/test

$>python makeTestOPCUAServer.py -f <your ICD file .xls/xlsx> -o <ServerOutputDir> 

the input ICD file  shall be the same used to generate the ACS component.The default output dir is "./SimulationOPCUAserver"

in the output you have someting like:

....

....

Working on: ['MyDevice']

File: /home/astrisw/pyGen/test/SimulationOPCUAserver/MyDeviceServerModel.xml  created

File: /home/astrisw/pyGen/test/SimulationOPCUAserver/MyDevice_opcuaServer.py  created

The Simulation server can be reached at: opc.tcp://127.0.0.1:52523/OPCUA/hwSimulator



$>cd ServerOutputDir

$>python <DeviceName>_upcuaServer.py



you should see something like this output:



Server Started!

Python 3.6.9 (default, Sep  3 2020, 15:28:31) 

Type 'copyright', 'credits' or 'license' for more information

IPython 7.8.0 -- An enhanced Interactive Python. Type '?' for help.



In [1]:



Insert exit at the In[1] prompt above.



To check the server open another terminal and insert the command:

$>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.
