IO-Link teach-in
The sensor supports two different IO-Link teach functions for all IO-Link switching channels (SSC):
–
Single value teach-in according to IO-Link specification
–
Device-specific teach-in
Carry out the following steps before teaching:
1. Configure the switching channel according to the application including switching mode, switching
logic and hysteresis.
The switching mode must not be deactivated (OFF).
2. Set the teach channel to the desired switching channel (parameter 0x003A).
Single value teach-in according to IO-Link specification
With the single value teach-in, SP1 and SP2 are taught in with separate commands. After each
command, the parameter set of the switching channel is checked for validity. If the parameter set is
valid, the teach point is immediately accepted as the switching point. If the parameter set is invalid,
the process is aborted.
1. Set the desired flow rate.
2. Perform the teach process: 0x41 for SP1 and 0x42 for SP2.
3. To set the second switching point, repeat steps 1 and 2.
For more information, see IO-Link Smart Sensor Profile.
Device-specific teach-in
The device-specific teach-in (0x4B) behaves in the same way as the manual teach-in on the device.
Instead of pressing a button manually, the two teaching points are set with the IO-Link command. The
chronological order is irrelevant. In the window mode and in the two-point mode, the 2 teaching points
are assigned to the switching points SP1 and SP2 in such a way that the parameter set is valid. The
