Industrial Networking in Practice
Like Duolingo, but for Industrial Networking in Practice. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Structuring and Communicating on the Plant Floor and Bridging and Defending the Boundary. It assumes you already know the basics.

Key ideas in Industrial Networking in Practice
- Level 0/1 covers field instruments and real-time controllers executing physical actions.
- Level 2 aggregates supervisory HMIs directly viewing immediate machine operations.
- Level 4 houses enterprise business servers entirely isolated from direct plant I/O.
- Unmanaged switches broadcast multidirectional packets to every connected copper port.
- Resource-constrained PLC network stacks crash or drop packets when flooded with ARP or multicast storms.
- IGMP snooping and port-level broadcast limits on managed switches protect PLC CPU cycles.
- East-west machine traffic needs bounded deterministic latency that wide switches disrupt.
- Traversing plant core switches exposes local automation lines to unrelated facility traffic spikes.
- Hierarchy of industrial network levels from field equipment to corporate business networks
- Keeping east-west packets local to cell switches guarantees continuous operation if uplinks fail.
- Why industrial switches inside work cells must filter broadcasts rather than using unmanaged hubs
- Stretching Layer 2 VLANs across different cells creates a shared fault domain.
- Layer 3 routing boundaries terminate Ethernet broadcast packets at the cell edge.
- SIS logic solvers require air-gapped physical cabling or certified safety protocols like PROFIsafe.
- Standard process control switches cannot mix non-safety and safety logic on standard unvalidated packets.
- Safety networks enforce deterministic fail-safe states independently of supervisory control.
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Industrial Networking in Practice the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
