Robot Controller Interfaces
Common interfaces
| Interface | Used for |
|---|---|
| Digital I/O | On/off signals with machines and fixtures |
| Analogue I/O | Sensors and proportional valves |
| Fieldbus | Communication with PLC and line controllers |
| Ethernet | Program transfer, data collection, diagnostics |
| Safety I/O | E-stops, door interlocks, safety PLCs |
Practice
Agree a signal schedule before wiring, and keep 10–20% spare points. Safety signals must never share ordinary I/O channels.
