ZhilianhaiInputs, Outputs and Fieldbus Basics
Interface types
| Type | Typical use |
|---|---|
| Discrete IO | Simple presence, valve and interlock signals |
| Analog | Pressure, force or speed signals |
| Fieldbus | Devices on a shared network |
| Industrial Ethernet | Robots, vision and controllers |
| Safety network | Safety devices and functions |
Design advice
- Reserve spare IO at commissioning; you will need it.
- Document the address map and keep it with the cell records.
- Use safety-rated communication for safety signals, not standard nets.
Interface choices depend on the controller and site standards. Confirm with the integrator.
