Introduction to this User Manual1.
This User manual has been developed for PLC programmers who intend to connect a
Datalogic Laser Marker to a PLC via ProfiNet/IO, in order to handle the Laser Marker and
its operations following the flow of the Production Chain.
All the screenshots and tests made as a reference for the creation of this User Manual
were made using the following versions of HW and SW:

Setup over ProfiNet/IO Network2.
In order to have ProfiNet/IO connection between the PLC and the Datalogic Laser
Marker, it is necessary to set up both elements: this chapter want to show the necessary
steps and the choices which the PLC programmer can make according to his needs, in
order to have communication between these two ProfiNet/IO devices.
2.1. Configuring the Laser Marker for use over PNIO
Some operations must be made on the Laser in order to have it working on an
Profinet/IO network; PLC programmers will need to assign on each Laser Marking a
Device Name and make changes to the Firewall Rules: moreover, the User, according to
his application will have to choose the dimension of the Input and Output Memory
Areas. These changes are described in the following paragraphs.
Basic net settings of the Laser Marker
The Datalogic Laser Marking systems can be discovered on an ProfiNet/IO network only
if a number of parameters on the Laser Marker and on the PLC match. The parameters
which should match are the following:
-Device Name;
-Size of Input and Output memory maps.
The Device Name of the Laser Marker can be changed following these steps:
a) Open the ‘Laser Configuration’on the Laser Marking System, by right-clicking
the Laser Engine icon in the Windows tray bar.
b) Once the Laser Configurator is open, select the ‘Network’ voice of the menu from
the left side of the interface and the Device Name can be found under the voice
‘Device Network Name’.

Advanced net settings of the Laser Marker
All Datalogic Laser Marking devices are controlled by the Windows Firewall, which by
default settings does not allow Inbound and Outbound ProfiNet/IO traffic; in order to
establish a ProfiNet/IO connection between the PLC and the Laser Marker, the user can
either completely disable the control of the Windows Firewall, or allow all Inbound and
Outbound traffic regarding ‘LaserEngine.exe’.
To create these Inbound and outbound rules regarding the Windows Firewall, the User
can follow this procedure on the Laser Marker:
1. Enter the Control Panel and select ‘Advanced settings’.
2. New Inbound and Outbound rules need to be set for the ‘LaserEngine.exe’
program: click on ‘Inbound Rule’ and then select ‘New Rule…’.
