Fieldbus Selection for Robot Cells
Pick the network your maintenance team can support.
Selection factors
| Factor | Why it matters |
|---|---|
| Existing plant standard | Spares, skills and diagnostics already in place |
| Cycle time | Determinism for fast handshakes |
| Device count | Scalability of the topology |
| Cabling | Cost of switches, connectors and cable runs |
| Diagnostics | How quickly a fault can be located |
Practical advice
- Standardise where you can; a second protocol adds training and spares cost.
- Keep safety traffic on a safety-rated protocol.
- Document the address map and the physical layout.
Protocol support varies by controller and device. Confirm compatibility before specifying.
