DocumentationĪ PDF manual for OpenOPC is included in this package inside the “doc” folder, written by the original author. Make sure to get similar responses from the system. > opc = OpenOPC.open_client("192.168.1.6") # IP address for OPC DA server

Now, go to your OpenOPC repository in the remote client node and change to the “src” folder.

> opc # here the "opc" object was created successfully

Type in the following instructions (also, follow the output):.

Then, open a command prompt to open a Python interpreter.

Go to your OpenOPC local repository (downloaded from here) and change to the “src” folder.

Make sure the “MatrikonOPC Simulation Server” is installed and running.

Make sure the “OpenOPC Gateway Service” is installed and running.

Python for Windows Extensions Build 228 for Python 3.7.

Go to your server station and make sure you have completed the following prerequisites: The idea here is to test the OpenOPC library in two scenarios.

Next, design a system architecture for OPC DA remote data communication (both the server and client nodes are in different machines):.

We want to use OpenOPC 1.2.0 and Python 3.7.6 on Windows to exchange data with a standard OPC DA server on a Windows system through an OPC client application. Prerequisites and Considerations Basic Settingsįollow these steps to prepare your work environment:

A free OPC automation wrapper (required DLL file).A system check module (allows you to check the health of your system for performance, free memory, tasks list, among others).An OpenOPC for Python library module (used to connect to an OPC server from both Windows and Linux).An OpenOPC Gateway Service (a Windows service providing remote access to the OpenOPC library, which is useful to avoid DCOM issues).To start working with OpenOPC and Python 3.7 on Windows, we need to know what’s included in the package:

However, if you want to try a different fork that works with Python 3.4+ (if you make some minor changes to the Python source code that affects Pyro4), go to the GitHub version of Anton D. Interested in the original version from Barry Barnreiter? Go here. The procedure described here allow us to integrate OpenOPC 1.2.0 with recent versions of Python (v3.7+) and Pyro4 (v4.80+) installed on Windows. Also, includes a Windows gateway service that enable non-Windows clients to also access OPC-DA calls. OpenOPC for Python is a free, open source and easy to use OPC (OLE for Process Control) library that works very well with the popular Python programming language (now, version 3.7) on Windows. It’s possible to use it from learning how the OPC DA protocol actually works to connecting to multiple servers and building applications for deeper data integration.

OpenOPC and Python 3.7 on Windows is the right setup when working with certain industrial automation projects that implement industry-tested OPC DA servers.
