IO-Link Application¶
iqmaxrefdes23 communicates with an IO-Link Master on COM3 transmission rate (230,4 kbit/s).
Note
When a device is switched to IO-Link SIO mode, sensors chip is switched to shutdown mode, microcontroller fall into HALT and restarting operation upon wake-up interrupt signal.
Process Data In¶
- Byte (MSB): Light intensity (from 0 to 255).
- Byte (LSB): [.......F - light intensity switch-point flag (1bit)].
Process Data Out¶
Be absent.
Commands¶
Can be run by IO-Link Index 0x0002:
