IO‑Link is een begrip binnen de industriële digitalisering en industriële communicatieprotocollen.
Definitie
IO-Link is een open industrieel communicatieprotocol dat intelligente sensoren en actuatoren verbindt met automatiseringssystemen via een simple point-to-point verbinding. Het enables parametrisatie, diagnostiek en data-uitwisseling met standaard onafgeschermde kabels.
Kenmerken
- Point-to-point connection: Direct communication tussen master en device
- Standard cabling: Unshielded 3-wire cables (power, communication, ground)
- Device parametrization: Remote configuration van sensor/actuator parameters
- Diagnostic capabilities: Real-time device health monitoring en error reporting
- Hot-swappable devices: Replacement zonder system downtime
- Vendor independence: Open standard supporting multiple manufacturers
- Backwards compatibility: Support voor traditional digital/analog devices
- Auto-configuration: Automatic device recognition en parameter download
- Data transparency: Bi-directional data exchange tussen fieldbus levels
