Robot Controller Architecture Choices
The controller decides how easily the cell connects to everything else.
What to compare
| Aspect | Consideration |
|---|---|
| Openness | Available interfaces and third-party integration |
| Determinism | Whether timing is guaranteed under load |
| Fieldbus support | Protocols your plant already uses |
| Safety integration | Whether safety logic can share the platform |
| Lifecycle | Support horizon and software update policy |
Practical checks
- Ask which protocols are supported natively versus through optional cards.
- Confirm that the controller can log and export production data.
- Check the spare parts and software support commitment in writing.
Architecture decisions are hard to reverse. Decide before the layout is frozen.
