Output Parameters; Sensor Front - CARLO GAVAZZI CA18CA Manuel D'instructions

Thanks to IO-Link it is possible to see the manufacturer information and part number (Service Data) of
the device connected, starting from V1.1. Thanks to the data storage feature it is possible to replace
the device and automatically have all the information stored in the old device transferred into the
replacement unit.
Access to internal parameters allows the user to see how the sensor is performing, for example by
reading the internal temperature.
Event Data allows the user to get diagnostic information such as an error, an alarm, a warning or a
communication problem.
There are two different communication types between the sensor and the master and they are
independent of each other:
• Cyclical for process data and value status – this data is exchanged cyclically.
• Acyclical for parameter configuration, identification data, diagnostic information and events
(e.g. error messages or warnings) – this data can be exchanged on request.

2.4 Output Parameters

The sensor measures five different physical values. These values can be independently adjusted and
used as source for the Switching Output 1 or 2; in addition to those an external input can be selected
for SO2. After selecting one of these sources, it is possible to configure the output of the sensor with
an IO-Link master, following the six steps shown in the Switching Output setup below.
Once the sensor has been disconnected from the master, it will switch to the SIO mode and keep the
last configuration setting.

2.4.1. Sensor front
When an object, solid or liquid, approaches the face of the sensor, the capacitance of the detecting
circuit is influenced and the sensor output changes its status.
2.4.1.1. SSC (Switching Signal Channel)
For presence (or absence of presence) detection of an object in front of the face of the sensor, the
following settings are available: SSC1 or SSC2.
The setpoints can be set from 0 to 10.000 units which represent the change of capacitance of
the detecting circuit. The higher the value, the closer the target appears to the sensing face of the
sensor, also a higher dielectric value of the target will increase the value. E.g. a metal target has a
higher dielectric value than a plastic target.
