7.4 Parameter setting during operation
u
Make sure that the sensor is connected to an IO-Link-capable module (master).
u
Read the sensor using suitable IO-Link software. Observe the
Ò
operating instructions of the
respective software.
u
Set the parameters, adjustable parameters (
Ò
IODD Description).
u
Check if the unit has accepted the parameter settings. If necessary, read sensor again.
u
Check whether the unit operates correctly.
For further information, please refer to the IODD description ( www.ifm.com ) or to the context-specific
parameter descriptions of the used parameter setting software.
7.5 Parameters
Name Description
SP1 / SP2
rP1 / rP2
Set points [SP1] / [SP2] and reset points [rP1] / [rP2].
Important:
[SPx] must be higher than [rPx]. If [SPx] is set to a value below [rPx], this is rejected by the device software.
The values for [SPx] / [rPx] are set in per cent of the maximum process value. The process value is defined as
follows:
Process value in air = 0 %, process value in tap water = 100 %
Setting range [SPx]: 4...98 %, step increment: 1 %
Setting range [rPx]: 2...96 %, step increment: 1 %, minimum hysteresis: 2 %
Reference values:
Aqueous / water-based media: SPx = 62 %, rPx = 54 %
Media with low water content: SPx = 35 %, rPx = 29 %
Oils, fats, powders: SPx = 8 %, rPx = 5 %
ou1 / ou2 [ou1] / [ou2]: output function for OUT1 / OUT2:
– [Hno] = hysteresis function/normally open
– [Hnc] = hysteresis function/normally closed
– [Fno] = window function / normally open
– [Fnc] = window function / normally closed
Parameter [ou1] also provides the option [tch]:
– [tch] = configure pin 4 as input for the teach signal
FOU1 / FOU2 Behaviour of the outputs OUT1 / OUT2 in case of a fault:
– [OFF] = output opens in case of a fault (factory setting)
– [On] = output closes in case of a fault
dFo Delay time of the outputs in case of a fault:
Setting range 0...5 s, step increment 0.2 s
dS1*

/ dS2*
)
Switch-on delay for OUT1 / OUT2:
Setting range 0...10 s, step increment 0.2 s
*
)
Parameter [dSx] is not available for LMT01A!
dr1 / dr2 Switch-off delay for OUT1 / OUT2:
Setting range 0…10 s, step increment 0.2 s
P-n Output polarity for the outputs (PnP or nPn)
7.6 System commands
tSP1 Teach switch point 1 to medium 1
• Full adjustment to medium 1 to be detected, automatically sets the switching thresholds SP1/rP1 for OUT1.
tSP2 Teach switch point 2 to medium 2
• Full adjustment to medium 2 to be detected, automatically sets the switching thresholds SP2/rP2 for OUT2.
