This reference design implements an IO-Link master with fast and deterministic timing with eight ports. Each port can be operated with independent bit rate and cycle timing. This design can be used to build a remote IO gateway to connect to OPC UA, Profinet, EtherCAT or Ethernet IP. A PRU-based frame handler provides timing flexibility and synchronization.
Features
- Eight IO-Link ports
- Supports IO-Link transmission rates COM1, COM2 and COM3
- Supports 400-μs cycle time
- 500-mA current per port
- All ports feature overcurrent protection and limiting
- PRU frame handler enables flexible timing
