Page 4: Introduction To This User Manual
Introduction to this User Manual 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. -
Page 5: Setup Over Profinet/Io Network
Public Setup over ProfiNet/IO Network 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. - Page 6 ‘Profinet’ section, choosing from the 3 possible sizes expressed in Bytes (64, 128 or 254). d) Once these parameters have been set, press ‘Apply’ followed by ‘OK’ on the bottom of the Interface.

Page 13: Configuring The Siemens™ S7-1200 Controller For Use Over Pnio
Public 2.2. Configuring the Siemens™ S7-1200 Controller for use over PNIO In order to create a Datalogic Laser Marker new ProfiNet/IO node in an already existing TIA Portal project, it is necessary to install the GSDML file. Once the new ProfiNet/IO node has been imported inside the project, there are some parameters which need to be set before starting to work on the data exchange between the PLC and the Laser Marker. - Page 14 Drag&drop Once you have imported the device into the HW configuration of your project, you will need to link it to the PLC which will communicate with the Datalogic Laser Marker Version Date Page 14/27 4/18/2019 ©...
