  • Entry
  • Associated product(s)

Description:
WinCC Scope is a tool enabling you to diagnose your system. It thus also makes it possible to check your system configuration.

Instructions
Proceed as follows to use WinCC Scope.
 

No. Procedure
1 Open the CCDiagAgent from the WinCC installation path (....\SIEMENS\WINCC\WinCCScope\bin).
2 Start WinCC Scope via Start > SIMATIC > WinCC > Tools > Scope.
3 How to proceed is described on the home page of WinCC Scope under "How to use the new Diagnosis Interface".

Instructions for Windows NT 4.0 users
 

No. Procedure
1 Install an Internet Explorer. You need the WINSOCK interface. Therefore, please use the TCP/IP protocol.
2 Configure MS-Loopback as adapter (you will find the adapter under "Start" ® "Settings" ® "Control Panel" ® "Network" ® "Network Card" ® "Add"). In this way the local computer can be addressed via a name (also local host).
3 Set up the network. Define the IP address and interface mask.
4 Start WinCC Scope with the CCDIAGAGENT.EXE file. You will find this in the Explorer under "<DRIVE>:\SIEMENS\WINCC\WINCCSCOPE\BIN". This starts the server. A small globe appears in the Icon Tray. Right-click on this globe to configure the diagnostics agent.
5 Then start the diagnostics help via "Start ® Simatic ® WinCC ® Scope". The WinCC Scope home page opens.
6 Set the URL to http://Name if you want to work with the network and access the WinCC computer from a remote computer. The name is the name of the computer on which the WinCC application is running.
If you want to start WinCC Scope locally, select http://localhost with the Internet Explorer or Netscape Navigator.
If you get the error message "DNS not available", you must make another change in the Control Panel. Select "Start" ® "Settings ® Control Panel" ® "Internet" ® "Connection". In the "Proxy Server" field you must activate the item "Bypass the proxy server for local addresses (intranet)" if you have selected the item "Set up connection via a proxy server".

WinCC Scope Home Page


You now see four links:

  • How to use the new Diagnosis Interface
    Information on how to use WinCC Scope and the requirements.
  • More Information from the Internet
    Page with more links to WinCC and Siemens Automation.
  • http://localhost
    Diagnosis information. If you cannot get a connection here, select
  • http://localhost:8000
    The diagnosis agent now selects the port 8000. Its standard port address of 80 is then used for something else.
System Messages and Operator Input Messages

The operator input messages are configured as follows:
Date, time, message number, computer, user, application, old value, new value, variable status, operating reason
Variable status: 0 == rejected, 1 == accepted

Configuration of a system message:
Date, time, message number, class, computer, user, application, error text
Class: 1 == Information, 2 == Warning, 3 == Error, 4 == Error message, 8 == Operator message 

However, the meanings cannot be generalized. These messages are given an ID by the system and written to a specific LOG file according to the ID. The messages contain not only "error messages", but also "normal information messages" to improve diagnostics.

WinCC Scope manages the system and operator input messages from the WinCC applications. They are forwarded to the message system of WinCC for further evaluation.

The messages are stored on each computer locally as .csv files in the ...\WINCC\DIAGNOSIS directory. There are three different logbooks for this:

  • Operator input messages: WinCC_Op_xx.log
  • System messages during startup: WinCC_SStart_xx.log
  • System messages during operation: WinCC_Sys_xx.log
  • License check: License.log
  • (xx == 01...99)

The files with the system and operating messages are located in WinCC Info ® Diagnostic Files.

The files written according to the cyclic buffer principle. Hence the files occupy only a specific space (number of files * size of files) on the hard disk. You can set the size and number of files individually for each logbook. You do this in the WINCC_LOG.INI file in the ...\WINCC\BIN directory. The default size is 64 Kbytes.

Security information
In order to protect technical infrastructures, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art IT security concept. Siemens’ products and solutions constitute one element of such a concept. For more information about cyber security, please visit
