9 Parameter setting
Parameter setting can be carried out via the IO-Link interface or via the operating elements on the
unit.
Parameters can be set before installation or during operation.
If you change parameters during operation, this will influence the function of the plant.
uEnsure that there will be no malfunctions in your plant.
During parameter setting the unit remains in the operating mode. It continues to monitor with the
existing parameter until the parameter setting has been completed.
Depending on the parameter setting, the parameters available in the menu may change.
9.1 Parameter setting via the unit keys
CAUTION
If the medium temperature is above 50 °C (122 °F), parts of the housing can increase in
temperature to over 65 °C (149 °F).
wRisk of burns
uDo not touch the device with your hands.
uUse another object (e.g. a ballpoint pen) to carry out settings on the unit.
Parameter setting process in general:
Intent Action
Change from the process value display to the main menu [●]
Change to the submenu Use [▼] to navigate to the sub-
menu (e.g. EF), then [●]
Selection of the desired parameter ▲ or [▼]
Change to setting mode [●]
Changing the parameter value ▲ or [▼] > 1 s
Acceptance of the set parameter [●]
Exit parameter setting without saving [▲] + [▼]
Return to next higher menu
(Repeat several times to reach process value display)
[▲] + [▼]
Return to the process value display > 30 seconds (timeout)
9.2 Parameter setting via IO-Link
Requirements for parameter setting via the IO-Link interface:
üA suitable parameter setting software, e.g. ifm moneo|configure
üThe Input Output Device Description (IODD) for the device, see documentation.ifm.com
üOne IO-Link master
uConnect the IO-Link master to a parameter setting software.
uSet the port of the master to the IO-Link operating mode.
uConnect the device to a free port of the IO-Link master.
wThe unit switches to IO-Link mode.
