IO-Link interface

1 IO-Link interface

Sensors in the GSX14E/…, IGSU14E/…, IGSU14E/..SD.. and GSU14E/… variant have a dual channel ar­chitecture. Available on pin4 is the IO-Link interface in accordance with specification 1.1.2 (July 2013) with
support of Smart Sensor Profile 1.0 (March 2017) with profile type SSP2.6. You can easily, quickly and
economically configure the devices via the IO-Link interface. Furthermore, the sensor transmits the process
data via the IO-Link interface and makes diagnostic information available through it.

In parallel with the IO-Link communication, the sensor can output the continuous switching signal for object
detection on pin2 (SSC1 by default) by means of the dual channel architecture. The IO-Link communica­tion does not interrupt this signal.

RW Teach value that is

stored after teaching.

The teach value contains
the taught switching
threshold, the hysteresis
and the used operating
principle for the label or
web material that is to be
detected.

With the possibility to
store multiple teach val­ues in the device and to
call them back up later if
necessary, the user is
able process various la­bel materials without the
operator needing to per­form a teach event.

see chapter 3 "Recipe
management"

RW 0…19 0 Storage location of the

teach value that is stored
after teaching.

Up to 20 teach values
can be stored simultane­ously in the sensor.

With the help of this
function, recipe manage­ment can be realized by
means of which the
teach event can be elimi­nated when changing to
a different label format.
The teach value that cor­responds to the given la­bel material is simply
loaded in the sensor and
the sensor works reliably
with the previously
taught teach values.

management"

corrected.

Recipe management

3 Recipe management

General description

The forked sensors of the GSX14E/.., IGSU14E/.., IGSU14E/..SD.. as well as GSU14E/.. variant can be
used to realize recipe management by means of IO-Link. At the same time, up to 20 teach values can be
stored directly in the sensor and called up if necessary. As a result, the teach settings are stored in the sen­sor for 20 different label formats.

When changing a roll to a new label format, it is then possible to simply load the corresponding recipe with­out needing to perform a teach event. After calling up the recipe for the new label format, the sensor oper­ates reliably with the teach value stored for that format. This eliminates the need to re-teach the sensor
when changing a roll to a different label format, and the format change is performed faster and more easily.

Tab.3.1: Parameters for recipe management

Index Parameter Action

99 Working Parameter Save current teach value after the teach event.

98 Working parameter

Storage location of the recipe (values 0…19)

load/save index

2 System command Value 226: Save work index

Save current teach value as recipe.

Value 227: Load work index
Load saved teach value as recipe.

The current teach value, which is saved after the teach event, is stored under parameter Working parame-
ter at index 99. It contains the taught switching threshold, the hysteresis and the used operating principle
for the label or web material that is to be detected.

The recipes are stored under parameter Working parameter load/save index at index 98.

New recipes are saved or existing recipes loaded via parameter System command at index 2.

Save current teach value as recipe

Ä Select the storage location of the recipe for the current teach value by writing a value from 0…19 in in-

dex98 (parameter Working parameter load/save index).

Ä Save the recipe in the selected storage location by writing value 226 (parameter Save work index) in in-

dex 2 (parameter System command).

Example:

1. Save teach value for label format A in storage location 3:
Write value 3 in index 98.

2. Save label format A as recipe at storage location 3:
Write value 226 in index 2.

If the sensor is taught to a new label format (e.g., label format B), the teach value for the new label format B
is again stored under parameter Working parameter at index 99. The teach value for label format A is still
available as a recipe in the sensor and can be reloaded if necessary.

Using the steps described above, up to 20 different recipes can be stored in the sensor.

Load saved teach value as recipe

Ä Select the storage location of the desired recipe by writing the corresponding value (0…19) in in-

dex98 (parameter Working parameter load/save index).

Ä Load the recipe form the selected storage location by writing value 227 (parameter Load work index) in

index 2 (parameter System command).

ð The recipe for label format A is thereby loaded with the corresponding teach value and active in the

sensor. The labels of this label format can be detected without reteaching the sensor.

Example:

1. Select recipe with the teach value for label format A from storage location 3:
Write value 3 in index 98.

2. Load selected recipe:
Write value 227 in index 2.
