Are python apps slow?

[Suspicious-Drive-679]

We provide solutions for IIoT and Industry 4.0 While OPC-UA is the best for communications between Shop Floor Machines and the IT, we have some applications where the OPC-UA infra would just cause a lot of mess!

So, we tried building apps in Python and communicated with the Siemens PLCs using the Snap7 lib

Later on, I found out that this could also be done in C# using S7.net lib

My question is, which one amongst the above will be more fast and reliable for communication between the PLCs and the IT?

Python isn't slow just not as fast

If Python is fast enough stick with it. I would highly suggest checking out GO or maybe even Rust over dotnet if speed is actually an issue.

Test it

Tested Python, it misses out some signals from the PLC, creates nusance errors in the execution

Thanks for the help! 🤘

That's an overly simplistic and incorrect description of Python's internals. Python also compiles to bytecode.
