The IO-Link teach-in is only available for the monitoring channels SSC1 and SSC2
Only one teach point is required for the switching point function threshold value comparator.
Avoid excess pressure at the sensor
There must be no excess pressure at the sensor during the teach-in procedure. If there is excess pres-
sure at the sensor, the teach-in procedure stops with the ISDU error message “Function currently not
available” (0x8036). The sensor remains in Run mode.
Sequence
1. Set teach value for distance.
2. Select SSC channel via IO-Link.
3. Send teach-in command.
Ä
As soon as the teach-in command is sent successfully, the teach-in process starts. The display
flashes alternately [t-IN], and [IOL]. Keys A, B and EDIT are blocked.
The teach point can be set several times with the command 0x41. The current measured pro-
cess value is always used here. If the sent command is invalid for the current switching/teach-
in mode, the ISDU error message “Function currently not available” (0x8036) is output.
4. The device returns the teach-in status at the end of the teach procedure.
Data type for teach commands
All teach commands are in the format UInterger8. They must be sent with the index 0x0002 (Standard
Command) subindex 0.
