IO-Link service data

The sensors which feature an IO-Link interface can be configured and diagnosed via the service data.

Parameters
Enabling/locking teach button:
Manipulation protection can be activated with this parameter.
Teach settings for operating levels 1 and 2:
Setting for the 2 teach operating levels which can be activated via the teach button or the teach input can be performed here.
When doing so, one of five possible teach sensitivities can be assigned to each operating level. A teach-in can be triggered via
the button, via an IO-Link command or via the teach input in SIO-mode.
Functions of pins 2 and 4:
The following functions can be configured for SIO operation for the inputs/outputs on pin 2 and/or pin 4:
- Switching outputs
- Activation input
- Teach input
Time module:
All normal time functions can be configured in a range of 10ms … 25s via the time module. The activated time function is effective
for both switching outputs.
Setting factory settings:
The factory settings of the sensor can be restored via the "Restore Factory Settings" system command.

Diagnostics (observation)
Reading out of the object distance:
The distance to the object, which is currently located in the light beam, can be measured via the Measure Distance system
command. The sensor function is not in operation during the measurement process. The result can be read out via the "Distance"
parameter.
Detailed information about the IO-Link service data and the IODD can be found at Leuze website.

Teach process
The teach-in of the reference scanner is performed without an object on the free reference (fixed background). When doing so,
two different sensitivity levels can be selected via the two operating levels. The sensitivity level is selected depending on the
homogeneity of the reference. 5 sensitivity levels can be assigned arbitrarily to the operating levels via the IO-Link interface. The
higher the chosen sensitivity of the sensor, the more reliable object detection is, but at the same time it is more likely for an
inhomogeneity on the reference to be signaled as an object. If it is not clear which sensitivity level should be selected, a low
sensitivity level should be chosen. If the object cannot be detected reliably, the sensitivity can be increased. After a new sensitivity
level has been selected via IO-Link, a new teach event must be performed so that the new setting goes into effect.

Available sensitivity levels

"very robust" This sensitivity level is suitable for very non-homogeneous references, such as colorful link conveyors
with rolls and very glossy elements or conveyors on which large water drops can accumulate.
"robust" This sensitivity level is assigned in the factory settings of operating level 1 and is suitable for non-
homogeneous references such as link conveyors with rolls or plastic conveyors with glossy elements.
"standard sensitivity" This sensitivity level is assigned in the factory settings of operating level 2 and is suitable for homo-
geneous conveyors or non-glossy dimple tape conveyors.
"high sensitivity" This setting should only be used for fixed references such as part of the machine base. This setting is
not suitable for conveyors.
"very high sensitivity" This setting should only be used for fixed, diffuse references such as a part of the machine base for
which a big change, e.g. due to soiling or fogging, is not expected.

Application example: detection of can containers on a link conveyor

In this application, the sensor is installed perpendicular to the conveyor. To ensure robust detection, the sensor should be
mounted within the scanning range and as close to the band as possible (e.g. 300mm for can containers). There is no minimum
distance to the container.
The sensor is assembled horizontally to the transport direction, i.e. the containers only run laterally under the sensor from the left
or the right. Moving objects in from the connector side or the indicator diode side should be avoided. A maximum sensor tilt angle
of 20° towards or away from the transport direction is permissible to bridge gaps between the containers.
For glossy link conveyors, the sensor must point at the band with an angle of 5° … 15°. It is recommendable to tilt the connector
downwards.
Optimal detection of different can containers is achieved when the sensor is aligned so that the light spot runs through the center
of a line of cans in the container and not over the gap between the cans in the container.
Since the background of a link conveyor is generally non-homogeneous, the "robust" teach process should be used in operating
level 1. Teach-in is executed directly on the stopped conveyor.

Locking the teach button via teach input (Pin 2)

A static HIGH signal (≥ 20ms) at the teach
input locks the teach button on the sensor,
if required, so that no manual operation is
possible (e.g., protection from erroneous
operation or manipulation).
If the teach input is not connected or if there
is a static low signal, the button is unlocked
and can be operated freely.
