- 2. Document conventions Terminology Used… Web interface Touch panel …for PXG3.W100 Desigo touch panel, PXM40 and PXM50 Illustrations Illustration excerpt are not labeled accordingly. Illustrations generally are not titled or subtitled. Wait… If an action (e.g. loading a page) takes longer, the animated "Busy Indicator" (wait symbol) is displayed in the middle of the working pane Tap, click Tapping an element on the touch panel is referred to as "tap". An instruction may read: "Tap "Logout". Tapping hand Illustrates tapping a button or function element.
- 3. Context of the descriptions in this manual. Topology Touch Panels, together with a PXG3.W100, help monitor and operate Desigo PX automation stations using web communication. They allow for: Local or remote plant operation. Displaying system texts, plant overviews, plant diagrams, simple alarm lists, schedules, and trends. Saving Favorites.
- 4. IT security The Desigo Touch and Web products implement the latest standard communications technologies. For this reason, compliance with IT security standards of the related installation environments as well as generally valid standards of the Desigo system is a must. See also CM110663. Note in particular the following issues with regard to Desigo Touch and Web: Use only strong passwords (password length, use of special characters, etc.). This applies to user login for plant operation during daily operation as well as to system operation as part of commissioning or service work. Do not use standard passwords. The password must always be unique and specific to the project. HTTPS must be used as standard communications protocol between the operator clients (Desigo Touchpanels, standard web browser) and the web inter- face PXG3.W100. HTTPS is entered in the URL to connect to the web inter- face PXG3.W100: Desigo Touchpanels should not communicate via the Internet with the PXG3.W100 web interface. The PXG3.W100 web interface should be accessible only via VPN over Internet.
- 5. Prerequisites The computer is operational. The PXG3.W100 is properly set up on the firmware side. For information on firmware setup, see the related online help of DNT (Firm- ware Download and Node Setup Tool) integrated in XWP. The configuration data is loaded properly in the PXG3.W100. Note: You can browse the pages at any time during commissioning by using the buttons < Back and Next >.
- 6. Commissioning The touch panel requires only a few steps to be fully functional. You may need to carry out the following tasks, however, depending on previous actions: 1. If the associated web interface has not been set up prior to commissioning, this must be carried out first. The touch panel cannot be commissioned with- out working PXG3.W100 (no control over functionality)). These actions must be carried out exclusively in Desigo Xworks Plus on the related PXG3.W100. To this end, consult the Desigo Xworks Plus online help either from within Xworks Plus or via file CM111006en.chm. 2.Customization of views and/or functions. These actions must also be carried out exclusively in Desigo Xworks Plus on the related PXG3.W100.
- 7. Firmware updates General With the devices PXG3.W100 (all versions) and PXM40 / PXM50 (>1.15.30.497) the firmware is updated in XWP using SSA-DNT; see E-learning module "Com- missioning the web server". To ensure operation of the devices on the most current firmware, the current firmware must be downloaded. PXM 40 / PXM50 ≤1.15.30.497 1. As a rule, the firmware of any PXM40/50s (referred to as “device”) can be updated using the FWDT (Firmware Download Tool). 2. This is particularly important if a FW update is not possible via DNT (Discovery and Node Setup Tool) due to technical issues. 3. In devices with FW version ≤1.15.30.497, updating the firmware via FWDT is mandatory, to be able to update the device using DNT in the future
- 8. Firmware updates Procedure 1. Disconnect the device from power. 2. Press/hold the Reset button, reconnect the device to power. 3. Wait until the orange LED flashes (ca. 10 seconds), then 4. release the Reset button. 5. Start FWDT. 6. Connect the device to the PC via USB connection. (FWDT discovers the device and enters the mode specific to these devices).
- 9. Firmware updates 7. Group box Select the firmware version > drop down list > select the accurate firmware version for your device. 8. Click Start Loading. (FWDT starts uploading and displays a progress bar.) 9. When the upload process has reached a certain level, an error message is displayed 10. Repeat now steps 1-8 above.(This time the upload will completely run the process) 11. Wait until the device has restarted following upload completion. 12. Disconnect the USB connection.
- 10. Factory reset web interface PXG3.100 Given certain circumstances it may be desirable or necessary to factory reset the device. If so, please exactly follow the procedure given below. Attention: The device will lose any password and other settings. Only the IP network settings remain the same as before Procedure 1. Power off device. 2. Power on device. 3. Wait for all LEDs to light up and turn off again, then 4. Press SVC button and hold until the green RUN LED flashes. Then 5. Release SVC button. 6. Wait for the device to fully start up unconfigured. (RUN LED is on, SVC LED flashes.) 7. Start firmware download process with SSA-DNT.

- 13. Supported Graphics Formats The wide-screen format 2144 x 1112 pixels achieves the best results for the work screen. If the image ratio is not correct, the image is adapted automatically to the work screen. The ratio, however, is always the same. Note: The work screen of both Desigo touch panels (PXM40 and PXM50) is 1072 x 556 pixels. Special note: Compress photos from high-resolutions cameras. General recommendation: Format png or jpg is the preferred format depend- ing on the application, as this format allows for achieving best results relative to resolution and min. memory requirements. Format Description png Recommended for plant diagram graphics jpg For photos1), e.g. of the own building as home screen gif For graphics without animation svg Rendered by browsers, thus resulting in possible differences. Inkscape is recommended as the tool to create graphics. SVG exported from Microsoft Visio is not supported.
