6.1.2 System commands
System commands are processes predefined by IO-Link to trigger specific functions. They are
controlled using a write access with a predefined value.

6.1.2.1
Parameter upload to the IO-Link master
This IO-Link system command is used to load all of the setting parameters for the SCTMi to the IO-
Link master and save them there.
6.1.2.2
Resetting to factory settings
This function is used to reset all settings parameters for the ejector to the factory settings. Counter
statuses, the zero-point adjustment of the sensor and the maximum and minimum values of the
measurements are not affected by this function.
6.1.2.3
Zero-point adjustment of the sensors (calibration)
Since the sensors installed in the ejectors are subject to variants based on the manufacturing process,
it is recommended to calibrate the sensors after the SCTMi is installed.
The vacuum connections of all of the ejectors must be ventilated to the atmospheric pressure before a
zero-point adjustment can be made to the sensors.
This system command is used to calibrate the sensors of all of the ejectors.
A zero offset is only possible by a maximum of
3% (FS) around the theoretical zero position.
The result of the calibration is reported by an IO-Link event.
