4 Function
Measuring cell:
•
The system pressure is measured by a ceramic capacitive measuring system.
•
The sealing of the ceramic measuring cell is free of elastomers and thus maintenance-free.
•
The medium temperature is recorded on the back of the ceramic measuring cell: Accuracy

Data sheet.
Signal transmission:
•
The unit can be operated in SIO mode (standard input-output ) or in IO-Link mode. The basic
operation mode is SIO. When connected to an IO-Link master, the unit automatically switches to
IO-Link mode. An additional manual switching is not required.
SIO-Mode:
•
Analogue signal measured pressure value 4-20 mA (pin 2).
•
Switching information (pin 4).
IO-Link mode:
•
Measured pressure value
•
Measured temperature value
•
Exceeding and falling below the limits of the measuring range
•
Device status
•
Switching information
•
Parameter setting
•
Device diagnostics (events)
4.1 IO-Link
IO-Link is an internationally standardised IO technology (IEC 61131-9) for communicating with
sensors and actuators.
Further information about IO-Link at:
IO-Link offers the following advantages:
•
Noise-immune transmission of several process values.
•
Parameter setting during operation as well as point-to-point at the desk.
•
Device diagnostics (events)
•
Data storage: Automatic new parameter setting in case of replacement.
•
Detection of connected units.
•
Freely definable parameters to identify the units in the plant.
