1 Description 1

1.1 General

The SIWAREX SecureDisplay software can be used to implement a display with verification capability for a SIWAREX electronic weighing system with verification capability. To achieve this, a program is installed on the SIMATIC HMI device which displays the weight value and certain status information in a manner suitable for verification. All data relevant to verification is output on the display. The contents of the verification display can be controlled using commands to the SIWAREX module. The contents to be displayed are generated and coded in the SIWAREX module, and the display is provided with them either directly from the SIWAREX module or via the connected SIMOTION CPU depending on the configuration. It is possible to configure the displays of several scales on one screen.

Description



1.2 Function description

The SIWAREX weighing module generates a measured value with verification capability which is displayed on a SIMATIC HMI together with the status information and further data relevant to the verification.

The measuring component of the software and the component for generating and coding the displayed value are present in the SIWAREX electronic weighing system. The function relevant to the verification capability for checking the displayed value, as well as display of the current measured values, are implemented on the display of the HMI device by means of the SecureDisplay.

The SecureDisplay is an application which is started once when the runtime is started, for example by means of a VB script in the WinCC configuration. The application is subsequently active in the background, and "waits" for instructions from the scale. Using special commands, the SecureDisplay can be switched into the foreground, for example, and then made "invisible" again in the background.

The mechanisms integrated in the electronic weighing system continuously guarantee that the displayed value cannot be changed accidentally or intentionally without the operator noticing this. In addition, use in the HMI device of the authentic SecureDisplay relevant to verification is continuously checked by the SIWAREX module.

A security value (hash value) is unambiguously assigned to each version of a SecureDisplay. This guarantees that there are no different software contents for a software version. The safety values are required during the verification and are displayed following the software version if activated per command. In the case of weighing modules with logbook, the logbook entries for the FW version of the SecureDisplay also include the associated security values.

If the requirements for verification are not fulfilled (for example incorrect parameterization of the SIWAREX, interruption in the connection between control panel and CPU, or similar), a weight value suitable for verification is not displayed, the weighing commands are disabled (with a non-automatic scale), and logging is not possible.

Up to 6 independent scales can be configured on one SIMATIC HMI device. 5 different display positions and sizes can be defined for each scale (each SecureDisplay). Therefore the appropriate size and position can be defined depending on the space on a faceplate. The possible positions and sizes are defined on the HMI device using an .xml file. Switching over is carried out per command to the SIWAREX electronics. The SIWAREX SecureDisplay checks that no displays overlap in a faceplate. The smallest possible display size of the SecureDisplay is defined in data record DS3, enabling this to be checked for readability during the verification.

With SIWAREX FTA, the following data can be superimposed live for information purposes:

current minimum weighing range,

current maximum weighing range and

current digit interval.

All required software components can be downloaded on:

Requirements





3 Supplement to SIWAREX FTA manual 3

3.1 General

The following description is a supplement to the SIMOTION function manual “Supplement to SIWAREX FTA Weighing Module”. It contains the configuration and control of the SIWAREX FTA SecureDisplay.

3.2 Communication between SIMOTION and SecureDisplay

The function block FBSiwarexFtaSecureDisplay() handles the communication between the Software SecureDisplay on the SIMATIC HMI device (or PC) and the SIMOTION controller.

This function block can just be executed in a cyclic task (e. g. BackgroundTask), direct after calling the system function block _FTA_control() for the SIWAREX FTA device.

The SIMOTION controller acts as TCP/IP server. The server functionality is in the function block FBSiwarexFtaSecureDisplay(). Internal following 5x SIMOTION system functions are used:

_tcpOpenServer()

_tcpCloseServer()

_tcpReceive()

_tcpSend()

_tcpCloseConnection()

The SecureDisplay acts as TCP/IP client. It establishes the TCP/IP connection to the SIMOTION controller.

Supplement to SIWAREX FTA manual



Table 1: Inputs of FBSiwarexFtaSecureDisplay()

Input Meaning

enable BOOL

With enable = TRUE the FB will be executed. The SIMOTION controller opens the server port. After one client has established the TCP/IP connection, the server port will be closed immediately.

With enable = FALSE the FB will not be executed anymore.

serverPort UINT, range of values: 1024..65535

The SIMOTION CPU acts as server and opens this port number. One client can establish a TCP/IP connection to this server port.

To switch between several SecureDisplays (HMI panels) this input serverPort can be changed during execution. It opens the possibility to use several SIMATIC HMI panels (SecureDisplays). But just one SecureDisplay can access the SIWAREX FTA device at the same time!

This server port must fulfill the port of the „DisplayCali.xml“ file!

clientIpAddress ARRAY[0..3] OF USINT

(optional)

Per default the clientIpAddress is 0.0.0.0, it means just one client with „any“ IP address can establish a TCP/IP connection to the server port.

In general this input is not needed!

In case of clientIpAddress is not 0.0.0.0, just one client with exactly this IP address can establish a TCP/IP connection to the server port.

It opens the possibility to use several SIMATIC HMI panels. Via the input clientIpAddress the related HMI panel can be selected, because each HMI panel has a unique IP address.




Table 2: Outputs of FBSiwarexFtaSecureDisplay()

Output Meaning

connected BOOL

The output connected = TRUE means that the client (SecureDisplay) is connected to the SIMOTION controller via serverPort.

If the input clientIpAddress in unequal 0.0.0.0, the output connected will just change to TRUE if the connected client has the IP address of the input clientIpAddress. If another client tries to connect, this output will not change to TRUE.

connectedClient IpAddress

ARRAY[0..3] OF USINT

This output shows the IP address of the connected client.

If just a specific client is authorized to connect (clientIpAddress unequal 0.0.0.0), this output will also show the IP address of the wrong connected client just for one cycle and for diagnostics. In this case the TCP connection will be closed immediately. The output connected will not change to TRUE while the wrong client is/was connected!

connectedClient Port

UINT, range of values: 0..65535

This output shows the port number of the connected client.

With each new connection the SecureDisplay uses a new port number.

If just a specific client is authorized to connect (clientIpAddress unequal 0.0.0.0), this output will also show the port number of the wrong connected client just for one cycle and for diagnostics.

receivedData DWORD

This output provides the received data from the SecureDisplay. These data must be forwarded to the FB _FTA_control() for a ‘handshake’ procedure.

Before calling the FB _FTA_control() these data have to be copied to an IN_OUT parameter scalaData.winccOcxWrite in each cycle, e. g.

sSiwarexFta_1.sScaleData.winccOcxWrite :=

fbSiwarexFtaSecureDisplay_1.receivedData;

error BOOL

This output shows an error, e. g. resource bottleneck in the SIMOTION controller (max. number of TCP connections).

A connection reset by the client is not an error. In this case just the server port will be opened again if enable = TRUE.

errorId WORD

This output shows the error number. For more details please check Table 6 of chapter 5.




Table 3: IN_OUT parameters of FBSiwarexFtaSecureDisplay()

IN_OUT Meaning

sendData ARRAY[0..31] OF BYTE

These data will be sent to the SecureDisplay after the TCP connection is established.

The FB sends the data after each change of sendData, but minimal each 100 msec to reduce the bus load.

Here you have to assign the crypto data of data record DR35 from the IN_OUT parameter scaleData of FB _FTA_control(), e. g.

fbSiwarexFtaSecureDisplay_1(

enable := boEnableSecureDisplay

,serverPort := 2001

//,clientIpAddress := (0,0,0,0)

,sendData := sScale.DR35.cryptoData

//,connected =>

//,connectedClientIpAddress =>

//,connectedClientPort =>

//,receivedData =>

//,error =>

//,errorId =>

);

The FB _FTA_control() should be called direct before the function block FBSiwarexFtaSecureDisplay!




3.3 Settings in the SIWAREX FTA device

The following parameters must be correctly set in the SIWAREX FTA, and are protected against modification following the verification by means of a calibration bridge:

3.3.1 New parameter „Factor for minimum display size “

The reserve parameter „xxxReserve1“ (BYTE) in data record DR3 is used as factor for the minimum display size in percent (see chapter 4.3, point 6).




The data record DR3 can be read by cmdNumber = 203. In the example (see figure) means DR3.xxxReserve1 = 16#14 that the smallest display size is 20%.

This value has to fulfill the smallest display size of the DisplayCali.xml file! If the smallest zoom factor defined in DisplayCali.xml does not agree with the zoom factor in data record 3, the weight value is hidden and the text "Start Up" is displayed. With a non-automatic scale, the scale functions are disabled in the status "Start Up". Please adjust the DisplayCali.xml file if needed.

3.3.2 New parameter „Version of SecureDisplay“

The reserve parameter „xxxReserve1“ in data record DR39 is used as additional version number to define the SecureDisplay version. As long as no connection exists between the HMI and the SIWAREX, the version is output at the top right in the SecureDisplay.

V<xxxReserve1>.<versionPrimary>.<versionSecondary>, e. g. V3.0.9

The version in DR39 hat to agree with the SecureDisplay version! With cmdNumber = 439, the data record DR39 resp. the version number in the SIWAREX FTA can be written. With cmdNumber = 239 it can be read.




3.3.3 Supplement to the command list of the SecureDisplay

The display is switched over depending on the requirements by means of commands to the SIWAREX FTA. The switchover refers either …

to the size and position or

to the content.

Depending on the displayed value, the display contents are either switched over permanently or reset after 5 s or 10 s to the original value.

The following table is a supplement to the table A-3 of the SIMOTION function manual “Supplement to SIWAREX FTA Weighing Module” (Appendix A 2). It shows the commands to control the SecureDisplay of a SIWAREX FTA.

Table 4: Supplement to table A.2 of the function block manual _FTA_control()

cmd Meaning of the command

27 Display regulation code

Display regulation code (OIML, ----…)

28 Display weighing mode

The current mode (AWI, NAWI, SWE…) is displayed.

29 Display SIWAREX FW version

The smallest display in the DisplayCali.xml file is shown. You can check whether the smallest display is still easy to read.

69 Display weighing range data

The weighing range data can be shown in the display with verification capability to permit a quick overview.



4 Installation 4

4.1 General

The SecureDisplay software consists of three files which must be downloaded to the SIMATIC HMI panel (or PC):

DisplayCali.exe,

StartDisplayCali.exe and

DisplayCali.xml

General .NET Compact Framework 3.5 must be installed on the HMI device. It can be installed if required, and is included with the SIWAREX FTA calibration set or online on:


4.2 Installation of .NET Compact Framework 3.5

A matching .NET Compact Framework is not usually installed on a SIMATIC HMI panel. Therefore please install it as follows:

1. Copy the following files to a USB stick. Please select the files depending on your HMI device!

NETCFv35.Messages.EN.cab

NETCFv35.wce.x86.cab (resp. NETCFv35.wce.armv4.cab)

2. Connect the USB stick to the SIMATIC HMI panel.

3. Start Explorer in the HMI device by double-clicking on "My Computer".

4. Navigate to the USB stick "Storage Card USB".

5. Install the two files in succession by double-clicking.

NOTE

Files disappear from the USB stick following the installation.

.NET Compact Framework and SecureDisplay must be reinstalled after a FW update of the HMI panel (e. g. from version 12.0.0.0 to 13.0.0.0)!


Installation



4.3 Parameterization of the display position and size

The size and position on the display panel are defined in the DisplayCali.xml file. This must therefore be edited according to the requirements in the project prior to transmission to the panel.

The DisplayCali.xml file can be edited, for example, using the free Microsoft software "XML_Notepad" (included in the calibration kit).

Procedure

1. Install the supplied setup XmlNotepad.msi on the PC if not already present.

2. Extract the SecureDisplay_Vx_yy_zz.zip file.

3. When XML Notepad is started, the DisplayCali.xml file in the “SecureDisplay” folder is opened.

4. Under "TreeView" on the left, expand the "DisplayEntry" and "Pos" folders. There are up to five "Pos" folders in a DisplayEntry directory. These describe the five different display sizes and positions.

Fig. 2: Parameterization of the screen view of SIWAREX SecureDisplay

Installation



5. Enter the parameters for the scales to be connected.

Title Name of display window

IP IP address of the SIMOTION CPU (e. g. 192.168.1.1)

Port Destination port number of the SIMOTION controller (e. g. 2001 for scale 1, 2002 for scale 2 etc.). One port should be set per scale.

SubNet Subnet mask (e. g. 255.255.255.0)

Gateway Usually identical with the IP address

Pos 1-5 Settings for the standard display size and position of the window (details in Point 6.)

6. Define the size and position of the display windows.

The "Pos" folder contains the elements …

X in Pixel X position of the top left corner of the display window

Y in Pixel Y position of the top left corner of the display window

Size Size of the display window in percent

The X and Y position data is in pixels. The number of pixels for the width and height is expressed by the screen resolution (example TP700 800x480 pixels).

The size data is a percentage, where 100% represents a size of 380x100 pixels (200%=760x200 pixels etc.). Values from 0% to 200% are possible.

If displays for various scales are to be shown on one faceplate, make sure when configuring that they do not overlap each other.

NOTE

If you wish to use the SecureDisplay for several scales on a panel, copy the “DisplayEntry” directory according to the number of scales and adapt the parameters (see Fig. 2).

Y

Installation



4.4 Downloading the SecureDisplay to the HMI device

1. Copy the "SecureDisplay" folder to a USB stick.

2. Connect the USB stick to the SIMATIC control panel.

3. Switch on the SIMATIC HMI control panel.

4. Following starting-up of the touch panel, start Explorer by double-clicking on "My Computer".

5. Navigate there on the USB stick "Storage Card USB" to the SecureDisplay folder.

6. Select the "SecureDisplay" folder by clicking (blue background).

7. Copy the folder per “Edit > Copy” into the temporary buffer.

8. Navigate in Explorer to the "flash" folder.

9. Insert the folder there per “Edit >Paste”.

4.5 Calling SecureDisplay on a SIMATIC HMI panel

Following successful parameterization of the SecureDisplay and the function blocks _FTA_control() and FBSiwarexFtaSecureDisplay() in the SIMOTION CPU, it is subsequently necessary in the WinCC project of the control panel to insert a script for single calling of the SecureDisplay when starting up the panel.

To this end, an internal Boolean variable (e. g. SecureDisplayActive) must be created in the panel project.

As a result of the script, SecureDisplay with the configured Position 1 is started during starting-up of the control panel. Commands 62, 63, 64 and 65 (see chapter 3.3.3) can be used to set other display sizes and positions.

Script example for single calling of SecureDisplay (see following figure too):

Sub VBFunction_SecureDisplay_1()

If SecureDisplayActive=False Then

StartProgram "\flash\SecureDisplay\StartDisplayCali", "", _

hmiShowNormal, hmiNo

SetTag SecureDisplayActive, True

End If

End Sub

NOTE

.NET Compact Framework and SecureDisplay must be reinstalled after a FW update of the HMI panel (e. g. from version 12.0.0.0 to 13.0.0.0)!

Installation



4.5.1 Hide SecureDisplay

If the SecureDisplay with verification capability is to be hidden when leaving the display, cmdNumber = 60 (see chapter 3.3.3) must be sent to function block _FTA_control() when changing the page.

4.5.2 Show SecureDisplay

The display is shown again using one of the commands 61 to 65. Commands 62, 63, 64 and 65 (see chapter 3.3.3) can be used to set other display sizes and positions. The command for the display contents is also configured with opening of the display or using a separate button in the display.

4.6 Logging / records

With the SIWAREX electronic weighing system with verification capability, the weighing operations can be recorded in a manner suitable for verification. With SIWAREX FTA, the records can only be read out using SIWATOOL.

NOTE

The called display must be designed such that the area of SecureDisplay defined in the xml file is "free". If status information, buttons or I/O fields are present in this area, they are no longer visible or usable since they are overlapped by the SecureDisplay!

Installation
