Behavior IO-Link¶
With Behavior IO-Link, the behavior of the pins during active IO-Link communication can be determined. The pin can either continue to perform its function or become inactive.
| Value | Name | Description |
|---|---|---|
| Pin 4 | ||
| 0x00 (0) | IO-Link | This is the communication pin. It cannot execute any other function during an active IO-Link connection. |
| Pin 2 | ||
| 0x00 (0) | Inactive | The pin has no function and is high-impedance. |
| 0x01 (1) | Normal Operation | The pin retains its function. |
Mode¶
The function of the pin can be selected with Mode.
| Value | Name | Description |
|---|---|---|
| Pin 4 | ||
| 0x00 (0) | Inactive | The pin has no function and is high-impedance. |
| 0x01 (1) | Digital Output | The pin works as a digital output. |
| Pin 2 | ||
| 0x00 (0) | Inactive | The pin has no function and is high-impedance. |
| 0x01 (1) | Digital Output | The pin works as a digital output. |
| 0x02 (2) | Analog Output | The pin works as an analog output. |
Signal Source¶
With Signal Source, the internal signal source for the pin can be selected. Various signal sources are available that can be output or read on a pin.

Warning
The voltage and current settins listed above (e.g., 4…20mA, 0…10V) only represent the nominal signal ranges of the configured meassurement range, not the absolute maximum or minimum values that may occur. Actual output may exceed these ranges in error or out-of-range conditions. More information about the analog output configuration can be found in the Analog Output section
