PI17xx
Electronic pressure sensor
8
The sensor provides the internal unit temperature as a readable parameter for diagnostic purposes.
4.2.2 Internal unit temperature
The internal temperature of the sensor can be read via the IO-Link channel. Measuring range:
-25...155°C (-13...311°F), resolution 1°C (1.8°F), pre/- 5°C (9°F). Information on measuring

Data sheet.
4.2.3 Counter overpressure events
The unit has a counter for overpressure events. The value above which a pressure is considered to be
overpressure can be set.
•
HIPC = Counter overpressure events.
HIPC counts how often the limit HIPS has been exceeded.
The limit must be exceeded for at least 0.5 ms.
•
HIPS = Threshold overpressure.
The [HIPC] can be reset with the reset command [Reset_HIPC] and the [Back-to-Box]. See:
In case of an interruption of the supply voltage, a maximum of the events of the last 10 minutes
can be lost, as these are summed up in the background and have not yet been permanently
transferred to the memory.
4.2.4 Optical localisation
The sensor can be localised in the plant via the commands [Blinken_An] / [Blinken_Aus]. When the
command is used, the switching status LEDs flash and [IO-L] is displayed.
4.2.5 Event logging
With IO-Link, the sensor has two logging mechanisms:
•
Event History (Parameter [Event_History])
•
Event Counter (Parameter [Event_Counter])
The last 20 events that occurred are recorded in the event history. As long as no event has occurred,
the value [noEvent] or [0] appears in this list.
The event counter (limited to 2
32
events) can be used to read how often a specific event has occurred
at the sensor.
The event counter and the event history can be reset using the IO-Link commands
[RESET_EVENT_HISTROY], [RESET_EVENT_COUTER] and [Back-to-Box ].
4.2.6 Operating hours counter
In the parameter [operating_hours], the hours are counted during which the sensor was active (cannot
be reset).
4.2.7 Switching cycles counters
The sensor counts the switching cycles at output 1 and output 2 in the [OUT_Counter] parameter and
stores this value every full 60 minutes.
A reset is possible with [Reset_to_zero] or the [Back to Box] reset.
