Course T530Chapter 22 Analyze 22.1 General Information 22.1.1 DescriptionThis chapter contains information about how to get more information concerning some diagnostics tools.22.1.2 ObjectivesOn completion of this chapter you will be aware of possibilities in the system to get more information concerning: Startlog/System Log Control Modules in on-line mode (“Show Control Modules in Run”) Application information System diagnostics22.1.3 Reference DocumentationUse the online help: Contents tab, Maintenance22.2 Lesson 1 Analyze22.2.1 DescriptionThis lesson contains information about how to get more information concerning some diagnostics tools.22.2.2 ObjectivesOn completion of this lesson you will be aware of possibilities in the system to get more information concerning: Startlog and System Log Control Modules in on-line mode (“Show Control Modules in Run”) Application information System diagnostics22.2.3 StartlogAll of the important events occurring during a transfer between offline mode and online mode is recorded in a text file, named startlog.dat. To display the contents of the file, select (Tools Maintenance Analysis Start log) from the menu of the Project explorer. Normally, the recording starts when the online entry is activated. On auto start, the recording starts on the first displayed dialog box. A new text file is created for every transfer between offline mode and online mode. If an auto start fails, the reason for the failure is presented in this Start log file.22.2.4 System LogThe system log contains all product printouts to inform you of warnings or errors. For example, if a task is aborted or if an overload in the controller occurs. This is written to the system log as information, a warning or an error. If you have unusual problems with a controller, the system log can be a very important information resource. Select (ToolsMaintenanceRemote systemShow System Log) from the menu of the Project Explorer to fetch the system log from the controller. When the last byte of the System log is fetched from the remote system (this may take some time if you are using RS232C), the System log is internally translated by a special walk back program to extract more information from crash dumps printed in the log. All crash dumps (not for Soft Controller) saved in the system log are translated. You can easily read all other information, like warning printouts, etc. When the system log is displayed to the user, it is shown in a text editor. The session.log is the current system log in your own PC for your running product.22.2.5 Write Heap StatisticsThe write heap statistics give a description of the memory, heap and disposition in an engineering station. The result of heap statistics is stored in a file called heapstat.dat. The result is intended to be stored and on request be sent, for example by e-mail, to your suppliers service department for closer examination. Start writing with the menu path (Tools Maintenance Analysis Write heap statistics).22.2.6 Application informationSelect (Tools Maintenance Remote System) from the menu in the project explorer and the Remote System window appears (picture below). Write the identity (IP address) of your controller and press Update. Press the Show Application Information button in the Remote System dialog box for information about applications running in the remote system. The Application Information dialog box appears with a list of the names of all running product applications in the system. Additional information appears in the columns; Application name, State of the application, Compilation date and time, Compiling station identity, Check sum of the application. The state of the application can be any of the following according to the MMS standard: UnRunnable, NonExisting, Idle, Running, Stopped, Stopping, Starting, Resetting and Resuming. If no application is present in the chosen system, you return to the Remote systems dialog box again. A message tells you that no application is present in the system. The information is not updated continuously. Press the Update button to refresh.22.2.7 Control Modules in On-line modeYou must be in simulate mode or in online mode to perform this operation. Open the CMD Editor on application level (Right-click on the name of the Application and select CMD Editor). From the menu of CMD Editor window: (View Show Control Modules in Online Mode), a green frame is visible around the Control Modules. Right-click on the green frame and choose Online Editor and the editor of the Control Module is visible.22.2.8 System diagnosticsYou can use the System Diagnostics function block type to measure and display: Stop time and memory usage during a controller download. Current memory in use Maximum memory used since the last cold start Fragmentation of the memoryValues can be updated either on command or cyclically. See Interaction Window. The system diagnostics window is only available in simulate mode. 22.2.8.1 System Diagnostics Interaction WindowThe System Diagnostics interaction window contains system memory and program download information. The interaction windows can be displayed in two versions, Simple and Advanced. If the values in the interaction window have not been updated the last 10 minutes, a warning is displayed indicating that the values displayed may not be true. To display the interaction window: right click on the System diagnostics icon in the project tree (picture below). Select Interaction Window from the menu (when you right-click).The Simple Interaction Window contains the following information:SystemDisplays the TCP/IP address of the supervised system.Cyclic loadDisplays cyclic load in percent.Latest update Displays the time of the last update.Cyclic updateCyclic update is activated by checking the check box. Cyclic update interval is set in time format, for example 5m (5 minutes).22.2.8.2 Advanced Interaction WindowClick on the Advanced button, and the Advanced Interaction Window is visible (picture on the next page). The advanced interaction window contains, in addition to the contents of the simple interaction window:22.2.8.2.1 System Memory InformationMemory sizeThe allocated heap size.Used memoryThe used part of the heap in bytes and percent of the total heap size.Max used memoryThe maximum used part of the heap in bytes and percent of the total heap size.Memory quotaThe part of the total heap size available when program changes are sent to the controller without any significant stop time. If the memory quota is exceeded an error icon is displayed.Check fragmentation nowMemory fragmentation is checked. If the fragmentation value is higher than 10%, the controller has lost that amount of usable memory.This operation takes a long time to execute and may cause a stop in the application22.2.8.2.2 Application Download InformationThe startup method (cold start, warm start or Simulate mode) is displayed.Stop timeStop time during the last download.Init peak memMemory used during initiation phase.Used memory at stopThe used part of the heap during the stop phase in bytes and percent of the total heap size.Max used memory at stopThe maximum used part of the heap during the stop phase in bytes and percent of the total heap size.Memory quota at downloadThe part of the total heap size available when program changes are sent to the controller without any significant stop time. If the memory quota is exceeded an error icon is displayed.This page is intentionally left blankThis page is intentionally left blankOsynlig text:Nsta sida mste brja p UDDA sidnummerLmna EN eller TV tomma sidor hr OVANFR.Nedanstende Section Break fr INTE tas bort !Komplettera tom sida vid beh
