Core Implementation with cpppo #

I’ve been building a Python-based solution to collect sensor data from a PLC, and I’ve nailed the protocol syntax implementation using cpppo. The core system is fully functional right now:

• I’ve set up a serialized loop that repeatedly reads tag data from the PLC in sequence
• The loop runs reliably without crashes, and I’m consistently pulling accurate values from the targeted tags

Testing Setup & Cross-Verification #

To validate the solution’s performance and data accuracy, I’ve connected the device running the Python logic to the PLC via a VPN tunnel. My test configuration includes:

• Continuous polling of a specific sensor tag
• This same tag is also being polled and logged by a separate non-Python system (to cross-check data consistency and ensure no conflicts between the two polling processes)
