4.5.2 Temperature monitoring
The calorimetric measurement method used by the sensors not only monitors the flow speed,
but also measures the approximate temperature of the media. Both process variables are recor-
ded and evaluated independently of each other. The current temperature is displayed via the
LED bar and—when connected to an IO-Link master (FS…2UPN8)—is output via a communica-
tion signal. The current temperature appears on the display when the [SET] touchpad is pressed
and held in display mode.
The switching output Out 2 (Temp) is used for temperature monitoring. The devices change
their switching status when the set switching point is reached due to a rising temperature. If
the temperature drops, the switching status changes when the switching point is undershot by
the hysteresis.
4.5.3 IO-Link mode
In order to operate in IO-Link mode, the device must be connected to an IO-Link master. When
the port is configured in IO-Link mode, bidirectional IO-Link communication takes place
between the IO-Link master and the device. To make this possible, the device is integrated via
an IO-Link master at the control level. First the communication parameters are exchanged, and
then the cyclic data exchange of process data (objects) starts.
In IO-Link mode, both cyclic and acyclic communication services for exchanging device data
(parameter values, identification data and diagnostic information) are available. The IO-Link
master always sends a request to the device first, and then the device responds. This is the case
both when the data is written into the device and read from the device.
4.5.4 SIO mode (standard I/O mode)
In standard I/O mode no IO-Link communication takes place between the device and the mas-
ter. The device only transfers the switching state of its binary outputs and can also be run via a
fieldbus device or controller with digital PNP or NPN inputs. An IO-Link master is not required
for operation.
The device parameters can be set via IO-Link and then operated at the digital inputs with the
appropriate settings in SIO mode. Not all functions and properties of the device can be used in
SIO mode.
