4 1 Introduction 1.1 General functionality The IEC communication channel is an Add-On for SIMATIC WinCC. It supports IEC MMS communication to intelligent electric devices (IED). WinCC is a client. The IED s are the servers. The IEC communication channel supports the following communication methods: MMS Read/Write Value control Report (Buffered and Unbuffered) A configuration wizard supports the import of ICD files and upload of configuration data from the IEC devices. The IEC communication channel is protected by a USB Dongle. The Dongle contains the license information. Warning! Without the dongle the channel works in demo mode. 1.2 Abbreviations IEC Communication protocol IED ICD CFC PLC OS MMS GOOSE SBOw NVL RCB - Intelligent Electric Device - IED Capability Description - Continuous Function Chart - Programmable Logic Controller - Operating System - Manufacturing Messaging Specification - Generic Object Oriented Substation Events - Select before Operate - Named Variable List - Report Control Block: Structure on the IED to configure reports IEC communication solution Page 4 of 33

5 2 Minimum System Requirements Please make sure that the computer on which you plan to install the IEC61850 WinCC Channel meets the minimum system requirements for the program to run: Operating System Comments Windows XP - SP3 (Required.NET Framework 3.5) Windows Server SP2 (Required.NET Framework 3.5) Windows Server Windows Vista - Windows 7 (x86/x64) - Windows Server 2012 R2 - supported from channel Version or higher - Disk Space: 30MB free disk space. - Free USB Port. - Installed WinCC 6.0 SP3 / WinCC 7.0 / WinCC 7.1 / WinCC or WinCC Minimal display resolution 800x600 - Reports require the IED to support Named Variable Lists (DataSets).

6 3 Installation procedure 3.1 Install Files Install the IEC61850 Channel only after WinCC has already been installed. Warning! Do not connect your USB Dongle before installing the USB Dongle Protection Software. To install the IEC61850 WinCC Channel: 1. On your installation CD: navigate to the WinCC IEC61850 Channel directory. 2. Start the ChannelSetupWizard.exe program. (Under Windows 7 as Administrator) 3. Follow the ChannelSetup wizard instructions. Note Under Windows 7 and Vista the ChannelSetupWizard.exe program must be started from Run as Administrator context menu. Now the USB Dongle can be inserted into a free USB port. IEC communication solution Page 6 of 33

7 3.2 USB Dongle The USB Dongle is only required for the Runtime Mode of WinCC. Configuration can be done without it. Without the USB Dongle the IEC Channel runs in Demo mode. In Demo mode one device can be connected for up to 12 hours. After 12 hours, the connection will be terminated. After restarting the WinCC Runtime the 12 hours start over again. The USB Dongle contains information about the number of supported connections. If the number of IEC connections is higher than on the dongle the user will see the following message when starting the runtime mode of WinCC: Picture 1 Error message Example: The dongle contains a maximum number of 20 connections and the project has 22 devices configured. When the WinCC Runtime starts, 20 connections will be established. The next two connections will be rejected. Note: The maximum number of connections can be found on the dongle: IEC61850 IYGBB XX 256 CONN In this case the number of connections is 256. If the USB dongle was disconnected during normal operation the user will see following message: Picture 2 USB Dongle problem In this case the existing connections will continue to work, but no new connections will be established until the problem is fixed. Lost connections will not be re-established. 3.3 Uninstall To uninstall the channel do the following: 1. Navigate to WinCC directory (normally C:/Program Files/SIEMENS/WinCC/bin). IEC communication solution Page 7 of 33

8 2. Start IEC61850Uninstall.exe program. 3. Follow the ChannelSetup wizard instructions. Picture 3 Uninstall window After the uninstall wizard is finished the WinCC IEC61850 Channel is uninstalled from PC. All USB Dongle drivers are uninstalled too. IEC communication solution Page 8 of 33

9 4 Using the channel It is suggested to use the report mechanism for communication. The channel will try to create configured DataSet on the device and use it with reports. If the creation of DataSet fails or configuration of Report Control Block is not successful, so the channel tries to poll the variables from IED with poll period of 2 seconds. The polling mode loads a lot the WinCC Server and IED device. 4.1 Add IEC61850 Channel to WinCC project After successful installation the channel can be added to a WinCC project with the following steps. - Select in the context menu of the Tag management the Add new driver menu item. - Browse to the IEC61850Channel.chn file (%WinCCInstallationPath%/bin). - Press OPEN - Now the channel is installed Picture 4 Installed IEC61850 Channel IEC communication solution Page 9 of 33

10 4.2 Add and configure a connection In order to add a new connection to an IED, use the context menu item Create Driver Connection. In the name field enter a Connection Description (don t use dots even if it is allowed). Note: Picture 5 Connection properties window It is important to complete this step with the OK button and then open the properties of the connection again Connection properties Open the Connection properties dialog. Each connection must be configured manually (user defined) or by importing the ICD file. It is recommended to use the ICD file. Note If you have problems with accessing the.icd file on Windows 7 or Vista choose the directory for.icd file where no administrator rights required. (e.g. My Documents ). IEC communication solution Page 10 of 33

11 Picture 6 IEC61850 connection properties (Device properties) The connection requires the following parameters: - IP address - Timeout Read/Write in milliseconds. After this time the request will be marked as failed and the channel will try to reconnect to the device. (Default value: 1000 ms) - Timeout Control in milliseconds. Extra timeout for control variables (see 4.3.2) - Path to the ICD file. If this option is chosen no more parameters have to be set. The ICD file must remain in place. The WinCC Channel tries to access the configuration from this file when starting the WinCC Runtime. - Origin string. For writing values the used Origin string can be either a normal text string or a chosen hex value. - Authentication. You can enable the authentication, choose a mechanism and set a password for the connection - If User defined is selected the following parameters must be set. They are required to establish a connection to the device: o ACSE AE Qualifier IEC communication solution Page 11 of 33

12 o ACSE AP Title ObjectID o Presentation selector o Session selector o Transport selector 4.3 Import wizard The import wizard helps to import variables from the ICD file or directly from the device itself into the WinCC Data Manager. Even when using the ICD file, it is recommended to have the IED connected during configuration. The structure of the specific device variables will be read directly from the device. If the device is not connected during the configuration all variables will be read from the ICD file. The import wizard can be opened any time in order to add new tags to the WinCC Data Manager. No variables will be deleted by the wizard. Variables already existing in the WinCC Data Manger will be updated with new settings if changed. Picture 7 IEC61850 import wizard from ICD file The user can delete tags with the help of WinCC explorer just as normal other tags. Tags can also be changed manually (e.g. Tag Name, see 4.4 for details) Create variables Create control variables IEC61850 WinCC Channel supports two types of control structures: SBOw and just Oper. The operation Cancel is not supported. There are two different ways to create the Control Tag: IEC communication solution Page 12 of 33

13 1. Using the import wizard 2. Using Variable Settings The Import Wizard detects if a command structure is selected and asks the user if he wants to import this structure as set of variables or as control variable: Picture 8 Import Wizard (Creation of command variable) The wizard will offer to create the control variable only if all children of this structure are selected Writing the Control Variable After the variable has been created, the user can set its values. A control variable is always 4 bytes long and has the following structure: Byte Index Description 0 (MSB) Flags: 1 Data Bit 0 interlocking Bit 1 Synchrocheck Bit 2 Test Bits reserved 2 Data (or padding for Bitstring) 3 (LSB) Data (If variable cltval is Boolean, only this byte will be used) IEC communication solution Page 13 of 33

14 Only 4 types of ctlval are supported: Boolean, Bitstring, Integer and Uinteger. For integer and uinteger the user can set only the first 3 bytes, for Bitstrings only 2 bytes (2nd and 3th) are used. E.g. if the user wants write 1 to the control structure as test, he must write (0x ) value into control variable. Note: Note: Byte 0 is most significant byte and byte 3 is less significant byte accordingly. Bitstring can have maximum length of 8 bits. Padding must be set in Byte 2, like 0x for 10 or 0x for 01. Byte 1 is unused and is equal to 0. All types of control variables are supported: - direct control with normal security - Select-before-Operate with normal security - Direct control with enhanced security - Select-before-Operate with enhanced security Actually Select-before-Operate will be written automatically: first SBO value and then without the pause the OPER value Create alarms using reports Alarms can be only created for complex variables in the IEC61850 channel. It depends on the IEC61850 device type if the report will be generated for a variable. In any case the IEC device must support Named Variable Lists to work with reports. If alarms are enabled for device, then the special dummy variable AlarmDummy will be created in the Tag Management for this connection. The purpose of this variable is the possibility to create the alarms in the Alarm Logging. This variable will never be changed and the alarm mechanism of WinCC is disabled in this case. IEC61850 channel generates alarms itself over WinCC API (ODK). Not all variables can be updated over reports (On change). Only process variables, like stval, are supported. It depends on IEC61850 Device Settings for communication via reports Two Report Control Block (RCB) Variables have to be assigned: one for status variables (functions constrain ST, CF, and so on) and one for measurement variables (MX function constrain). Status RCB will be configured with BufTm equals to zero and measurement RCB with BufTm equals to 500ms. It is suggested to use unbuffered reports for measurement values and buffered for status values. The RCBs will be set up with 30 seconds integrity period. That means the IED will send report in any case every 30 seconds. Following triggers will be set: - Data-change - Quality-change IEC communication solution Page 14 of 33

15 - Integrity - General interrogation The purpose of these variables is to enable the reporting for a special Data Sets (Named Variable List, NVL) created by the IEC channel. The selection of these variables can be done in the Connection Properties dialog under the Report settings button. Both report types are supported: buffered and unbuffered. Picture 9 Selection of a control variables for report. The location of the alarm data set can be defined in the Subtree name for dataset field or with the Browse button. By default the location is the root of variables tree and the Subtree name for dataset field is empty. The dataset name can be set by user, e.g. to use one IEC61850 device with 2 instances of WinCC. Default name is WinCCChannel. Only characters a-z, A-Z, 0-9 and _ are allowed. The first character has to be a letter. The maximum path to a variable is 64 characters long. By default the data set will be created in the root of the variable tree. If the following message appears when starting WinCC Runtime: Picture 10 Error window. try to point to another location of the alarm data set with the Browse button (e.g. IED_000xCTRL/LLN0): IEC communication solution Page 15 of 33

16 Picture 11 Alarm data set location. IEC communication solution Page 16 of 33

17 Creation of alarm. With the help of Import Wizard the user can choose for complex variables the alarm type. There are 3 types of alarms: 1. If Zero - Coming warning if variable becomes 0; - Going warning if variable value becomes 1; 2. If non Zero - Coming warning if variable becomes 1; - Going warning if variable value becomes 0; 3. On Change - Coming and immediately going warning will be generated by every change of the variable value; 4. On Position - Four alarm entries in the Alarm Logging will be created for this special variable: closed, opened, intermediate, bad. For each state of the positioner coming and going alarms will be generated. E.g. if the positioner will be switched from closed state to opened, following alarms will be generated: - Closed going - Intermediate coming (Optional) - Intermediate going (Optional) - Opened coming It depends on IED if the intermediate alarm will come or not. Picture 12 Create alarms in the Import Wizard User can select alarm type from types defined in the WinCC project. This type will be applied for all alarms selected in the current wizard window. User can modify the alarm type later in the tag properties or direct via the Alarm Logging Window. There is a possibility to set alarm type for multiple variables by selecting of tags (with Ctrl or Shift button) and calling the corresponding item from the context menu. IEC communication solution Page 17 of 33

18 Picture 13 Multiple variables alarm type selection After click on Import button the WinCC channel will try to find the default alarm text in the ICD file (if it is configured). The reports will function properly only if positive message shown. Picture 14 Positive Import report Important: There is a software bug with WinCC Version by creation of the alarms. If you see following or similar message: Picture 15 Negative Import report IEC communication solution Page 18 of 33

19 Update 3 must be installed for WinCC. It can be found under: Created alarms can be controlled and modified in the Alarm Logging window. If the ICD file is defined, the WinCC Channel will try to find in this file the text for the alarm. After importing a variable with report the user can check the settings for this variable. In parameters there is an alarm index from Alarm Logging and additional parameters like alarm block and alarm type. Picture 16 Variable parameters The alarm number will be created for every alarm variable in the alarm logging. It can be controlled or adjusted in Alarm Logging Window: Picture 17 Alarm Logging with created alarms for IEC61850 IEC communication solution Page 19 of 33

20 Alarms for IEC61850 channel starts with number Alarms will be generated from the IEC61850 channel, so all settings concerning message bit or tag will be ignored. User can change the properties of the alarm for every particular variable. Picture 18 Single message parameters For instance Class, Type and Group can be changed to higher classes. Or priority can be set to 1. IEC communication solution Page 20 of 33

21 Picture 19 Single message text properties All texts are fully customizable. E.g. it can be created warning with text Switch in the main building is now Warning: Picture 20 Single message Tag/Action properties If the user recreates the alarm with the Import Wizard, all custom settings will be overwritten with default values.

22 Description of alarm processing After staring WinCC in Runtime mode the following data set will be created in the IEC device. Before disconnection this data set will be deleted every time. Picture 21 IEC Browser after the WinCC in runtime mode with /WinCCChannel branch open IEC communication solution Page 22 of 33

23 After creation of a data set the selected control report variable will be set to valid settings. Picture 22 Display of unbuffered report control variable in IEC Browser. Note: The IEC Browser can be found on the DIGSI program CD (V 4.80 and newer). IEC communication solution Page 23 of 33

24 If all settings are correct the user can see the coming and going alarms with timestamp from IEC device in the WinCC Alarm Logging. Picture 23 WinCC runtime Complex variable Many variables have due to its value also a quality code and a timestamp. The import wizard detects automatically these and sets as default to read these variables together with quality and timestamp (see picture below) and report it to WinCC. Picture 24 Import Wizard (Selection of complex variable) The wizard enables the checkbox for complex variables (timestamp & quality) if it was found in the structure. The user can unmark this when no alarm is set and use it as a normal value. Then quality and timestamp will be created by WinCC when reading a value. By choosing an alarm type for an unmarked complex variable, it will be automatically marked as with timestamp. IEC communication solution Page 24 of 33

25 4.4 Manual configuration The user has the option to create tags manually. This procedure can also be used to change variables created by the import wizard Create variables In order to create a variable manually the user must create a new tag in the WinCC Data Manager. Tag name is freely configurable. Picture 25 Tag creation Usual tag options can be set in the standard Tag properties dialog. Picture 26 Standard tag properties window Specific IEC61850 options will be set with the Select button. IEC communication solution Page 25 of 33

26 If the device is set up with the ICD file the user can select a variable name from the tree. All other settings will be adjusted automatically. If the user selected a complex variable (with timestamp and quality, see Complex variable) and wants to treat it as a normal variable, this can be done by unmarking the checkbox with timestamp. Picture 27 Channel specific tag properties (using ICD file) If the user has no ICD file for this device and no connection to the device established the variable name, variable type, variable length and complex variable options must be set manually. IEC communication solution Page 26 of 33

27 Picture 28 - Channel specific tag properties (without using ICD file) It is not possible to read or write the whole structure. Only individual structure parameters can be mapped to WinCC tags. The variable name must be exactly the same as in the device Create control variables The user can manually create a control variable by selecting the corresponding structure in the Variable Settings window (With CO in the name). IEC communication solution Page 27 of 33

28 4.4.3 Create alarms using reports Picture 29 Variable settings window An established connection to the device is required for the manual alarm creation. Picture 30 Variable Settings window The alarm will be created by the channel if the trigger type is unequal to None. The user must define the alarm type to create an alarm. If the user changes the trigger type from non- None (e.g. If Non Zero ) to None the alarm for this variable will be deleted from project. IEC communication solution Page 28 of 33

29 4.4.4 Manage changes All variables and alarms created by the Import Wizard can be manually modified by the user with the help of the normal WinCC Data Manager tools Delete variable The variable can be deleted via context menu element: Delete. Picture 31 WinCCExplorer Data Manager context menu (Delete) Change variable settings To modify the variable, select Properties from the context menu. Picture 32 WinCCExplorer Data Manager context menu (Properties) IEC communication solution Page 29 of 33

30 Picture 33 WinCCExplorer Tag properties With the select button the user can edit specific settings for IEC If the device is connected or the ICD file was used during the configuration the settings window will look like this: Picture 34 IEC61850 Specific tag properties (ICD file or connected) Now, the user can select another IEC61850 variable for this tag. All other settings like type and length will be read from ICD file or directly from the device. IEC communication solution Page 30 of 33

31 If no ICD file was used for this configuration and there is no connection established to the device the Variable settings window will look like this: Picture 35 IEC61850 Specific tag properties Now, the user can change Variable name, Variable type, Variable length and complex variable options manually. It is not possible to set up alarms because there is no direct connection established. IEC communication solution Page 31 of 33

32 4.5 Redundant WinCC Server It s possible to use IEC61850 channel with redundant WinCC Server. There are some changes which have to be made on the servers Different dataset names and locations WinCC Master and Slave servers have to use different dataset names and different variables for alarm control. See Settings for how to change the names Same alarm numbers Make sure that the variables for alarms have the same alarm numbers on WinCC Master and Slave server. See how to check the alarm numbers. If the alarm numbers are differ, delete variables on one server and create new ones in the same order as on the other server. The best way to use redundant WinCC Server is to create full project for one server and then copy it to other. Do not forget to change the RCBs and DataSet names.
