6.2.5 IO-Link events
In accordance with the IO-Link specification, a variety of IO-Link events are provided by default.
These events include, for example:
General system errors
Voltage supply errors
…
The SCTMi also generates system-specific IO-Link events such as:
Vacuum calibration successful or failed
Valve protection function activated
H1 not reached
Manual mode activated
Various condition monitoring events
…
The generated IO-
Link events also correspond to the ID codes generated as “Extended Device
Statuses” to a great extent.
A detailed description of all the IO-Link events can be found in the data dictionary, which can be
downloaded together with the IODD as a ZIP archive from www.schmalz.com.
6.3 Functions of the individual SCPSt ejectors
6.3.1 Switching points
Two separate switching points can be set for the ejector. Each switching point has an activation point
and a corresponding hysteresis. The system vacuum is constantly compared to the set values for the
switching points during operation.
An LED displays when the switching point for H2 is reached.
The set values for H2 must be lower than the values for H1. The exact conditions for the
settings are provided in the SCTMi data dictionary.

System vacuum evaluation
Once the system vacuum reaches the value for H2, the following responses are triggered:
The process data bit for H2 is set
The H2 LED in the display illuminates
Once the system vacuum reaches the value for H1, the following responses are triggered:
Depending on the selected control function, vacuum generation is interrupted
The process data bit for H1 is set
