4 Function
• The unit displays the current system pressure.
• It generates output signals according to the operating mode and the parameter
setting.
• It moreover provides the process data via IO-Link.
• The unit is laid out for fully bidirectional communication. So, the following
options are possible:
-Remote display: reading and display of the current system pressure.
-Remote parameter setting: reading and changing the current parameter
setting.
-Using the FDT service program ifm Container, the current parameter settings
can be stored and transferred to other units of the same type.
The program library of the available DTM objects can be found at:

Device-specific parameter lists for IO-Link parameter setting are available at:

4.1 Operating modes
The operating mode is defined by the wiring (→ 6 Electrical connection) and
automatically recognised.
4.1.1 2-wire operation
OUT2 (pin 2)
Analogue signal proportional to pressure 4…20 mA or 20...4 mA
4.1.2 3-wire operation
OUT1 (pin 4)
• Switching signal for system pressure limit value
• Communication via IO-Link
OUT2 (pin 2)
3 options:
• Switching signal for system pressure limit value
• Analogue signal proportional to pressure 4...20 mA
• Analogue signal proportional to pressure 20...4 mA
