(21)4 Contact/Support (22)S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dQuestionWhich functionality can be realized by the 3SK2 diagnostic display (MLFB 3SK2611-3AA00)?S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dAnswerThe diagnostic display offers easy fault location without PC/PG. It supports fast problem solution by detailed fault messages. There is no engineering in advance in the basic module necessary to connect the display. The connection outside of the control cabinet allows easy access.Furthermore with two integrated memory slots you can use the diagnostic display for saving and transferring of projects. This simplifies commissioning of identical machinery and allows quick device exchange in case of fault. It is especially helpful by use of the 22,5 mm width basic module which has no exchangeable memory module.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d1Product overviewBeside the 3SK2 diagnostic display (MLFB 3SK2611-3AA00) the 3RK3 diagnostic display (MLFB 3RK3611-3AA00) still exists. The following table shows an overview of compatibility and functionality.Table 1: Compatibility diagnostic display 3SK2 and 3RK3It is not possible to transfer projects with the 3RK3 diagnostic display.For both displays you need a connection cable, which is available in different lengths and flat and round version: MLFB 3UF793*-0*A00-0.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2Controlling and monitoringBesides the fault detection via monitoring function within the software, the diagnostic display helps for easy problem analysis without connection of PC or PG by detailed error messages. Even in case of no failure project and status information are helpful which are available at the display.In the following image you can see a simplified menu overview of the diagnostic display.Figure 1: Menu structure diagnostic displayS i e m e n s A G 2016 A l l r i g h t s r e s e r v e dMenu items have no fixed numbering and can be hidden in the display depending on the connected device and current status. The menu items …Status Info“, …Status“ and …Configuration Transmission “ are shown in detail as they are more relevant for this FAQ.In the menu item …Status “ the state of all in- and outputs can be read out (e.g. “Switching output Switching ON Condition not satisfied ”). Comprehensive project information (e.g. Config-CRC, Project Engineer) can be found in the menu item …System Configuration “. In case of troubleshooting the menu item …Status Info “ is helpful. Here you can see detailed error messages and warnings. All status information which are available in Safety ES can be shown at the display. If no errors are present the menu item is empty.By means of an example with guard door monitoring and emergency stop theeasy diagnose in case of fault and no fault will be shown subsequently.Figure 2: Logic plan application exampleS i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.1 Preparation in the softwareThere is no previous engineering of the diagnosis display in the software necessary. The display can be plugged in without any effort in advance.For easy error tracking it is helpful to assign informative names to the function elements which will be shown in the diagnostic display. Furthermore all added project / hardware information can be read out in the display.2.1.1 Filling in of project informationIn …Identification“ and …Configuration“ information regarding project and hardware configuration can be filled in.Figure 3: Filling in of project informationS i e m e n s A G 2016 A l l r i g h t s r e s e r v e dFigure 4: Filling in of hardware informationIn the main system the diagnostic display can be added on system slot 1 optionally. This is only for documentation purpose and is not mandatory. All project information can be found in the diagnostic display in the menu item …System C onfiguration“.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.1.2 Preparation for detailed status informationFor easy diagnose it is advisable to name the function elements.Figure 5: Naming of function elementsBy double-clicking on the respective function element a symbolic name can be assigned in the window …properties“. T his name is displayed as further information in the diagnostic display. It is helpful to assign names for all input elements (e.g. “Emergency Stop”) as well for all output elements (e.g. “F -output”).S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.2Displaying of plant informationTo read out information at the diagnostic display an active connection to the energised basic module must be established. There mustn’t be any additional connection from the PCs/PGs via the diagnostic display to basic module. In this case the display is locked.2.2.1Reading out of project informationInformation regarding the project or hardware can be found in the menu item …System Configuration “. In the menu item …Project“ details regarding Config- CRC, Time Stamp, Release and Project Engineer are listed. Certain information are provided automatically from the system. Other information like …Project Engineer “ are only available if the corresponding fields were filled in in thesoftware (see chapter 2.1.1 Filling in of project information).In the menu item …Slot 3“ details regarding the used basic module can be found.Table 1: Project- and HardwareinformationS i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.2.2 Reading out of status informationThe full information concerning input and output elements can be found in the menu item …Status“.The elements are displayed as follows:Figure 6: Displaying of status/status infoFor this example the guard door is opened, the Emergency Stop was pushed and released but not acknowledged yet. Thus the output is not activated. These information can be read out in …Status / Input Elements “ as well …Status / Output Elements “.E-Stop 1 (symbolic name of the element),S i e m e nsA G 2016 A l l r i g h t s r e s e r v e dProtective Door (type of function element)You can read out status information which are available as element status in the Safety ES (e.g. …Timer running “, …Wa iting for Start“).S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.3Fault diagnosticTroubleshooting with the help of the diagnostic display will be explained by means of the application example of figure 2. There is a cross circuit between input 1 and input 2 of the emergency stop with element number 1.In case of fault detailed information can be found in the menu item “Status Info “. According to the default setting of the display the status info will be directly shown on the start screen in case of a fault (Setting adjustable in …Display Settings/ Statu s Info“)Table 2: Error messages in case of Cross-CircuitThe same procedure applies to other faults like discrepancy fault or fault within the feedback circuit. Below the element you find then the error message ‚Dis crepancy violated ‘ or ‚Feedback Circuit invalid ‘. All element messages which are available in Safety ES can be shown on the diagnostic display as well.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3Transferring of projects by the help of the diagnostic displayThe 3SK2 diagnostic display (MLFB: 3SK2611-3AA00) has two internal memory slots at which Safety ES projects can be stored.NoteThis functionality is only available for the diagnostic display 3SK2611-3AA00. The 3RK3 diagnostic display (MLFB: 3RK3611-3AA00) has no internal memory slots and it is not possible to connect it to the 3SK2.3.1PreconditionsTo be able to transfer Safety ES projects from or to the display an activeconnection to the running basic module must be established. Furthermore it is not possible to have an additional connection from the basic module to the PG/PC via the diagnostic display. In this case the display is locked. Transferring of projects is possible with both types of 3SK2 basic modules (3SK2112, 22,5mm width/ 3SK2122, 45 mm width) as well as with the 3RK3 Advanced and 3RK3 ASIsafe.Preconditions for saving projects in the diagnostic display/ reading configurations from the deviceTo save projects within the diagnostic display 2 memory slots are available. If a project was already stored on the selected memory slot and you read out a new configuration on the same memory slot, the old one will be replaced. There are no restrictions for reading out configurations. It is possible to read out not approved and approved configurations. The device can be in configuration or safety mode. If the protection level ‚write protection‘ was selected by password for the project which will be read out from the basic module, the protection level will be copied to the configuration in the display as well.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dHinweisThe protection level ‚Read Protection ‘ should not be activated in the basicmodule (3SK“/3RK3). In this case it is not possible to read out any configuration. Thus it is not possible to copy a project with Read Protection. This can be set after download via the Safety ES Tool.Preconditions for transferring of projects to the basic module It is possible to transmit a project to the device on condition that: - Device is running in configuring mode. - No password for device access is set.- The configuration on the basic module is not approved or there is no configuration on the basic moduleIf one of these conditions is not fulfilled the download of the project fails. In case that the download fails it is possible to download the project by resetting thebasic module to factory settings via reset button (See manual 3SK2 chapter 8.1/ manual 3RK3 chapter 6.4.4.5). Afterwards the device runs up in configuring mode and the project can be downloaded.DANGERAccidentally start possibleThe operator has to ensure that the configuration is downloaded to the correct machine, otherwise it can lead to a dangerous situation.NoteThe menu …factory settings“ in the diagnostic display refers only to the diagnostic display and not to the basic module. By executing the command the configurations in the diagnostic display among others will be deleted.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3.2 ProcedureFor reading out a configuration from the basic module an active connection to it is necessary. Downloading a project from Safety ES to the diagnostic display is not possible without the basic module.Saving a configuration in the diagnostic displaySelect the favoured Memory Slot e.g.Table 3: Backup of a projectThe project is now saved in the selected memory slot in the diagnostic display.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dThe project information of the saved project (Name, Project Engineer, Company, Config-CRC, Time Stamp, Approval, Cycle Time …) can be read out in the corresponding memory slot.Transmission of a configuration from the diagnostic display to the basic moduleTable 4 Write project to deviceThe configuration is now saved in the basic module.The project information of the downloaded project (Name, Project Engineer, Company, Config-CRC, Time Stamp, Approval, Cycle Time …) can be read out in “System Configuration/ Project”.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dNoteWhen downloading an approved configuration to the basic module the device first stays in configuring mode. To change to safety mode turn off and on the basic module. After running up, the device changes automatically to safety mode.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3.3Use cases3.3.1 Fast device exchangeIn case of a faulty basic module the approved configuration can be transferred fast and easily to the new basic module by the help of the diagnostic display. Thus the plant operation can continue quickly.Figure 7: Fast device exchange NoteBack up the Safety ES project straight after successful commissioning of the safety application to the diagnostic display.3 Transferring of projects by the help of the diagnostic displayWorking with the 3SK2 Diagnostic displayEntry-ID: 109482844, V1.0, 04/201621S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3.3.2 Fast commissioning of same applicationBy help of the possibility to download projects from the diagnostic display the commissioning of identical machinery can be sped up. After successful function test and approving once the safety program can be downloaded to the other machinery.Figure 8: Fast commissioning of identical machinery4 Contact/SupportWorking with the 3SK2 Diagnostic displayEntry-ID: 109482844, V1.0, 04/201622Si emensA G2016Al lrigh tsr ese rv ed4 Contact/SupportSiemens AGTechnical AssistanceTel: +49 (911) 895-5900Fax : +49 (911) 895-5907Mail: ******************************** Internet: www.siemens.de/automation/support-request。
