Best Practices for Reliable Communication in Industrial Networks?

Hello everyone,

I’ve been trying to learn more about communication systems used in industrial automation, particularly between PLCs, HMIs, and other field devices.

From what I understand, protocols like Modbus and Ethernet/IP are commonly used, but I’m curious about real-world experiences when it comes to reliability and troubleshooting.

What are some best practices you follow to ensure stable communication in your systems? For example, things related to network setup, wiring, or common mistakes to avoid.

I’d really appreciate any insights or lessons learned from actual projects.

Thank you.
