Building Technologies Commissioning – IT security 2014-08-15
1.2 IT security
The Desigo Touch and Web products implement the latest standard communica-
tions 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 op-
erator 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: „https://.........“
·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 Inter-
net.
1.3 Prerequisites
·The touch panel is unpacked and possibly already installed in the control panel.
See also:
[4] Desigo PX automation and control system, mounting and installation guide
CA110396
·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.
See the XWP online help CM111006en (chm).

the buttons < Back and Next >.

1.4 Touch panel commissioning – Step-by-step
1.4.1 About procedures
The following step-by-step procedures consider all actions, settings, etc. It is pos-
sible that, in the past, you may have applied and now wish to continue a different
procedure. The procedure described here merely shows the procedure identified
as best by development.
1.4.2 Procedure
1. If not yet done: Connect the Desigo touch panel to the corresponding network
plug using the network cable (RJ45).
2. If not yet done: Connect to power.
3. Wait for the touch panel to start.
---> This process may take a few seconds; the Language page is displayed.
4. Select the language.
---> 16 languages are integrated. English is the default language.
5. Save with Next.
---> The page “Network Settings – IPv4” opens.
Note
Two ways are available for the following step:
a. Automatically using DHCP (self-explanatory).
b. Manual via the alphanumeric keypad.
Below, we describe how to proceed with a manual entry. The procedure for IPv4 is
virtually automatic for the DHCP method.

Building Technologies Compatibility & limitations – Desigo touch panel and standard clients 2014-08-15
2 Compatibility & limitations
2.1 Desigo touch panel and standard clients
The PXG3.W100 web interface supports local operation via Desigo touch panels
as well as operation via standard web browser on commercial operator units. Due
to the open interface based on standard web technology and dependent on the
different use cases, users can clearly benefit from advantages offered by the vari-
ous operator units.
The Desigo touch panels are an integral part of the plant, optimized specifically to
operate the Desigo building automation and control system:
·No end user access to lower operating system functions.
·Alarms are displayed on the operator unit even if the screen is inactive.
·Siemens guarantees compatibility and product replacement or system up-
grades throughout the entire life cycle.
·Special functions for permanent connection and plant monitoring (7/24
Watchdog).
Standard operator units (tablets, PCs, notebooks, smart phones, etc.) supplement
local operation and allow for remote access and operation using personal devices.
Standard operator units are designed for temporary plant access and are subject to
other innovation and lifecycles.
2.2 Desigo Touch and Web – Application examples
PXM40/PXM50 Standard Clients
ûüûMobile use
üûIntegration in control panel door
üûFull screen – no user access to operating system.
üûLED for alarm indication.
üûPermanent alarm monitoring - reliable 7/24 operation.
ûüTemporary plant operation via WAN/LAN.
üûSystem compatibility, product life cycle.
When using a standard client, the following must be considered.
·Desigo Touch and Web uses cookies. As a result, the security settings on the
related client may require redefinition.
·If a standard client is connected to PXG3.W100, and if no user action occurs
during 3 hours on this client, the location definition of the standard client is
disconnected automatically.

2.5.3 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.
Format Description

jpg For photos
1)
, 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.
1) The best results are achieved at the above resolution (2144 x 1112).
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.

2.7 Firmware updates
2.7.1 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.
2.7.2 PXM 40/PXM50 ≤1.15.30.497
As a rule, the firmware of any PXM40/50s (referred to as “device”) can be updated
using the FWDT (Firmware Download Tool). This is particularly important if a FW
update is not possible via DNT (Discovery and Node Setup Tool) due to technical
issues. –
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.
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 devic-
es.
7. Group box Select the firmware version > drop down list > select the accu-
rate firmware version for your device.
The Select the firmware version dropdown list will appear only if there’s
more than one firmware version available.
8. Click Start Loading.
---> FWDT starts uploading and displays a progress bar.
