12.3 System condition monitoring (CM)
The overall status of the ejector system is displayed as a status traffic light using 2 bits of process data in-
put byte 0. All warnings and errors are taken into account when defining the status of the display.
This basic display provides immediate information about the status of the ejector.
The table below shows and explains the various status traffic light patterns:

12.4 Warnings and Error Messages in IO-Link Mode
In IO-Link mode, status information is available in addition to the error messages displayed in SIO mode.
More details on this can be found in the final section of the enclosed Data Dictionary, "Coding of Ex-
tended Device Status (ISDU 138) and IO-Link Events".
Any condition monitoring events that occur during the suction cycle cause the system status light to im-
mediately switch from green to yellow/orange. The specific event that caused this switch can be seen in
the "Condition monitoring" IO-Link parameter.
