Functions of the MARKING system app: - Marking Editor: easy and mobile marking of marking material. - Application Wizards: efficient and step-by-step creation of application-specific marking solutions. - Application Guide: quickly and easily find the application-specific marking materials - no special knowledge of the field is required. - My projects: manage the projects you have created in a structured and clear manner. - Dashboard: the current printing status at a glance at any time. - Barcode scanner: easily and quickly call up matching marking solutions for Phoenix Contact terminal blocks. NOTE: Please note that the MARKING system app requires different permissions on your device for the full functionality. Bluetooth permission Without the permission to use Bluetooth, MARKING system is unable to connect to the available printers. Location permission Without the permission to access your location, MARKING system is unable to find the available Bluetooth printers. The location sharing is technically needed because we use the user-friendly BLE (Bluetooth Low Energy) technology to communicate with the THERMOMARK GO. With the help of BLE technology, available printers in the immediate surroundings can be automatically found and connected to the app. Camera permission Without the permission to use the camera, MARKING system is unable to scan barcodes.
