mod_openopc is a full featured implementation of the OpenOPC library for Python. It is cross platform compatible (full Python 2.5 and up). We used to recommend running it on a POSIX platform (Unix / Linux), but thanks to modest efforts since 2014, performance in Windows OS environments is excellent.
syphon is an extension for mod_openopc, to monitor telnet devices (serial devices) that sit on Serial -to- Ethernet bridges (such as barcode scanners) and export parsed data to an OPC compliant device (such as a PLC).
The goal of this project is to implement an OPC UA communication stack using the python programming language. Currently we are working on a series of articles, describing how we can use python to implement the communication stack. Some code snippets have already been written!
