LN2000 Software System  (click to download)   1 System Management Software (StartUp) 1.1 General In LN2000 DCS, system management software is an ever-running program (the interface of Startup application is shown in Figure 1.1-1), which is used to collect, sort and save the real-time data of the process stations and collect the start/stop statuses of all stations as well as share them with other applications through the common memory. Its functions also include the user management, initiating other programs, operating process stations and system synchronization.   Figure 1.1-1 User Interface of System Management Software STARTUP 1.2 Startup Double click the icon of system management software Startup, a user register dialog box will pop up (as shown in Figure 1.2-1). User name and Password are needed to be entered. After confirmation, the interface shown in Figure 1.1-1 comes out. The user “administrator” is a super user with an initial password of “adm”. This user has entire operation authority of engineer station. The other names and passwords are set by the super user, and details are shown in “1.6-1 User Management”. There are two operation modes: offline and online. During normal operation, the [online] mode should be selected. When no network adapter is installed and it is required to configure offline, the [Offline] mode should be selected. In offline mode, the buttons of the following functions required to operate in online condition will turn grey and be unable to operate: process station operation, trend display, alarm display, system diagnosis, system synchronization and file uploading. [System Information] can diagnose the operation statuses of the two network adapters belonging to the two network segments of the computer. In case of indicating abnormal adapter operation, modification should be performed on time.   Figure 1.2-1 User Register Dialog Box 1.3 Startup Other Application A program will be initiated by pushing the relative button of this program on the STARTUP interface. When any user authority is limited, its relative button will turn grey and this program is not initiated. 1.4 Operation of Process Control Station A process station operation dialog box will pop up when pushing the button of a process station (as shown in Figure 1.4-1). Corresponding operation can be carried out depending on the status of master and slave stations. 1.4.1 Operation procedure 1. Select station number of the PU station to be operated; 2. Accomplish the following operation: · Download database to the master station. The dialog box shown in Figure 1.4-2 will pop up after click.

Download database to standby PU station Database and SAMA graphic can be downloaded to standby PU station (in following status) after modification of database configuration (add or delete data point) or SAMA configuration and the downloading period is about 10s. After downloading, transfer the master and standby station to activate the modified database point or control logic. Note that the contents of master PU station and standby PU station are different. 3. Copy database from master PU station to standby PU station In self diagnosis program (Selftest), the contents of master and standby PU stations can be judged identical or not through the color state of process control station. The standby station may be in partly tracking status (tracking identical configuration section of master and standby stations) or initial status. To make the standby station in completely tracking status, the database should be copied to standby PU station from master PU station. 4. Transfer master and standby PU station The function is to transfer the master PU station to standby PU station, and transfer the standby PU station to master PU station. 1.5 Synchronization This function can automatically synchronize the historical station and the super user can manually synchronize the historical station. Auto-synchronization: Automatic synchronization can be realized by online broadcasting the local time in a specified interval by the station (historical station) which has an identical IP address with that in the HisIP configuration file. Super user manual synchronization: by clicking this button the local time will be broadcasted to whole network segment. The other computers’ local time will be modified as the broadcasted time.   Figure 1.5-1 successful indication of LN2000 synchronization Then a dialog box indicating successful synchronization will pop up, as shown in Figure 1.5-1. If GPS module is equipped, the synchronization will be carried out by the GPS system. 1.6 User’s Management   Figure 1.6-1 Super user management interface The authority of other users can be added, modified or deleted by the super user, as shown in Figure 1.6-1. 1.7 File Uploading The dialog box shown in Figure 1.7-1 will pop up when click the button [file uploading] in the main view shown in Figure 1.1-1, and then input the entire IP address (as shown in the File uploading dialog box).The uploaded files from process control station will be saved in relative station number under project\RUN in the local current route.   Figure 1.7-1 File uploading dialog box   Figure 1.7-2 Dialog box of successful file uploading 1.8 Exit System The view shown in Figure 1.8-1 will be displayed after clicking the button [Exit System].

SAMA Graphic is used to combine functional algorithm blocks internally defined as per required operational processing logic and download them to process control station LN-PU after compiling for calling and execution. SAMA Graphic configuration system provides user convenient human-machine interfaces for creating, editing and compiling SAMA Graphics. SAMA Graphic configuration is carried out as per pages. Supported by this software, the compiling of programs is transferred to the organization and drawing of algorithm blocks. It is only required to select algorithm blocks from block library and connect these blocks with signal lines as per specified data processing flow.   Figure 3.2-1 Startup interface of SAMA Graphic configuration software 3.1 File Route Configuration Requirement of SAMA Graphic There should be two folders under the “Project” folder in the current route of SAMA Graphic configuration software. The folder DataBase contains database files from which database information is read by the SAMA configuration software. Meanwhile, the folder Fbd is used to contain files for SAMA Graphic (file for number 1 station is named as sama_1.fbd, and the rest may be deduced by analogy), to provide information used for lower computers (information file used for graphic configuration software of No. 1 station is called graph_1.fbd, and the rest may be deduced by analogy). 3.2 Startup of SAMA Graphic System management software StartUp.exe and should be initiated firstly prior to the startup of SAMA Graphic configuration software so as to access LN2000 main control view. Click the button “SAMA Graphic configuration” and then it will enter the startup interface of SAMA Graphic configuration software (as shown in Figure 3.2-1). Click the station number in the list dialog box of “Please select station number” and click the “Confirm” button (or double click the target station number in the list dialog box), and then it will enter the edit display. Before performing detailed SAM configuration, relative station file should be opened (if exists. Otherwise, the new station file should be created by adding a process station from database). 3.3 File Operation All items for file operation are listed in the main menu of “File”: “Station switchover”, “Save”, “Print”, “Print Preview”, “Print setting”, “Set project name”, “Upload lower operation file”, “Save as other station” and “Exit”. The menu is shown in Figure 3.3-1.   Figure 3.3-1 “File” menu of SAMA Graphic configuration system 3.3.1 Station Switchover Station switchover is accomplished via file operation. Click item “Station switchover” in the menu of “File”; if the station is modified but not saved, a dialog box will pop up promoting whether to save the modification. The station number can be selected after confirmation (as shown in Figure 3.3-2). The dialog box is identical to the one at the initiation of the software.   Figure 3.3-2 Prompt dialog box of station switchover 3.3.2 Save of File Station configuration information can be directly saved in the Fbd folder under the current route of SAMA Graphic configuration software by clicking item “Save” in the menu of “File”. (Files are copied to the Fbd folder of the project subdirectory under current route of SAMA Graphic configuration software with a name format sama_n.fbd, where n refers to station number).   Figure 3.3-3 Print preview interface of “Transverse”   Figure 3.3-4 Print preview interface of “Longitudinal” 3.3.3 Print Files will be printed on A4 papers with a title block including company mark “Shandong Luneng Control Engineering Co., Ltd.”, “Design”, “Approve”, “Date”, Project name, Page description and “Drawing Number”.

To select blocks in a certain area, drag the mouse to select the range and make the blocks and lines in checked status as shown in Figure 3.4-2. The edges of selected blocks and lines are marked with red squares to separate them from unselected blocks. Operations of Cut, Copy, Paste and Delete can be performed on selected algorithm blocks.   Figure 3.4-2 Algorithm block “Select” operation of SAMA Graphic configuration 3.4.2 Search Algorithm Blocks linked to database points can be searched via this function. Select item “Search” in menu of “Edit”(as shown in Figure 3.4-1), or click “Search” button on the toolbar, and then a dialog box of “Search target algorithm block” (as shown in Figure 3.4-3) will pop up, which is a non-mode dialog box (i.e. it can be operated at other locations while it is opened).            Figure 3.4-3 Dialog box of “Search target algorithm block” Figure 3.4-4 Display of Search results This dialog box is composed of three sections: nominated search object combined dialog box, search button and search result list. For the drop-down object search combination dialog box, the followings are included: All analog input points (AI); All analog output points (AO); All resistance thermometers (RT); All thermocouples (TC); All digital input points (DI); All digital output points (DO); All amount magnitude points (AM); All logic magnitude points (DM); All time magnitude points(TM); All normalized analog input points among stations (NAI); All normalized analog output points among stations (NAO); All normalized digital input points among stations (NDI); All normalized digital output points among stations (NDO); All forced and retained algorithm blocks There are totally 14 items. All algorithm blocks linked to specified points in the database will be displayed in the search result list (as shown in Figure3.4-4) by selecting one of the foresaid items and pushing the “Search” button or the key “Enter”; double click the algorithm block (e.g. Page:1 Block:3), and the page where the block is located will be found and the block will also automatically be in selected status. In addition, by inputting point name in the combined dialog box and pushing the “Search” button or the key “Enter”, the relative block will be displayed in the list if the algorithm block is linked to specified point; otherwise, “no target block is found” will be displayed in the list dialog box, providing this point is not in the database. 3.4.3 Number Statistics of Algorithm Block The dialog box of “Algorithm block statistics” (as shown in Figure 3.4-5) will pop up when the item “Algorithm block counting” in the menu of “Edit” is selected. This dialog box is a non-mode dialog box (i.e. it can be operated at other locations while it is opened). The times that all algorithm blocks are used are detailed in the dialog box by the system in accordance with block types. Times of usage of individual algorithm blocks under each group will be displayed by clicking the icon . In the lowest layer of the structure, page number and block number of each block are shown. Double clicking the item aforesaid, the page where the block is located will be called automatically by the system and the selected block will be in selected status.   Figure 3.4-5 Prompt dialog box of algorithm block statistics 3.5 Search Function This function is used to select items to be displayed in the SAMA configuration interface from the following: tool bar (displayed default), status bar (displayed default), mesh (undisplayed default), frame (undisplayed default) and algorithm block number (displayed default). Search menu is shown in Figure3.5-1.   Figure 3.5-1 Search menu of SAMA Graphic configuration If the icon  is shown in front of a menu item, then the item is in the selected status and its relative content will be shown in the interface of SAMA Graphic configuration; otherwise, the menu item is in a cancelled status when there is no icon   in front of this item and its content will not be displayed. Among these options, the items [Mesh] and [Algorithm block number] can affect the print output, i.e. if the item [Algorithm block] is selected, then the algorithm block number will be printed in case of printing of SAMA Graphics; if this item is cancelled, the algorithm block number will not be printed out. The item [Frame] does not affect the print output, i.e. the frame will be printed out no matter this item is selected or not. If this item is selected, then the frame will be displayed in the SAMA graphic configuration interface. In case of configurating an algorithm block, it should be put inside the frame. If it is put outside of the frame, these algorithm blocks will be printed outside of the frame, even not printed out (print output can be browsed via Print preview). 3.6 Creation and Edition of Algorithm Block and Connection Line algorithm blocks are divided into 9 groups: signal source block, input and output block, mathematics calculation block, logic block, selection function block, control function block, time function block, linear block and nonlinear block. For details of such algorithm blocks, please refer to relative content in the “LN2000 Algorithm Block Manual”. 3.6.1 Creation of Function Algorithm Block Click any item in the dropdown menu “Function algorithm block” in the main menu, or click relative item in the tool bar, a tool bar will pop up on the left screen containing all blocks belonging to selected function block group. Description of functional algorithm block will appear when the mouse is moved to the tool bar. Click the block required for selection and move the mouse to the drawing area, then the cursor will turn to a cross shape and a target block can be drawn by clicking the left key. 3.6.2 Creation of Connection Line The operation relationship between blocks is indicated by the connection lines between blocks, which is an important part in SAMA Graphic. There are two kinds of connection line: solid line and dotted line, which respectively refer to analog signals and digital signals. In this SAMA Graphic configuration software, there are two ways to create a connection line. one way is to move the mouse to the area where the algorithm blocks can be connected by lines (input end is indicated by an arrow and output end is indicated by a triangle), press left mouse button (the cursor turns to a cross shape) and move the mouse to create a connection line; the other way is to move the mouse to the area near connection lines, press right mouse button (cursor will turn to a cross shape) and then move the mouse to create a connection line. 3.6.3 Edition of Function Block Property 3.6.3.1 Edition of Normal Algorithm Block Property Most of the function blocks are not connected to the database, thus having no contact with blocks on other pages and stations. Property edition of this kind of algorithm block is described below taking “Add function block” as example, as shown in Figure3.6-1. Where, the page number of a block is created automatically and can not be modified. The series number of algorithm block in this page can be modified. If the modified series number has existed, prompt information will be displayed when pressing “Confirm” button. The input end of an algorithm block can be empty and the initial value of an empty input end can be set (if the value is not modified manually by the user, the empty end will be set as default value) which will be used in case of lower station calculation.   Figure 3.6-1 Property dialog box of add function block If the input end of an algorithm block is connected with a line, its relative edit column will turn grey and be unchangeable, e.g. AI1 shown in Figure3.6. Then other parameters of the algorithm block can be set. 3.6.3.2 Property Edition of Algorithm Block Connecting to Database Point The analog input function block, analog output function block, digital input function block, digital output function block, value function block, logic function block and time function block of the input and output function block and the PID control function block, analog manual station function block, digital manual station function block and setting value function block(as shown in Figure3.6-2)）of the control function block group should be connected to database points. A list of required database points is contained in the property dialog box of these function blocks and the information of these database points is read from the database files.   Figure 3.6-2 Algorithm block required to connected to database points   Figure 3.6-3 Function block property dialog box of analog output end Each of the following points in the database: such as analog output, digital output, value, logic and time points which have output feature shall only refer to one algorithm block in the SAMA graphic. To minimize faults during configuration, those data points which have been connected to other algorithm blocks shall be deleted from the data list in the property dialog box (as shown in Figure 3.6-3) of the algorithm blocks which will be connected to these points. In doing so, no repeating with other algorithm blocks will take place when selecting data points and the possibility of configuration fault will be greatly reduced. 3.6.3.3 Property Edition of Connection Block between Pages Configuration may be required to be carried out in several pages because of large amount of algorithm block in a station. The transmission of relative data between pages is performed by calling algorithm blocks. The parameters to be called by other pages should be connected to the output ends (including digital and analog output ends) between pages. The input ends between pages are used to call values from other pages. The calling input ends between pages perform the calling according to the page number of specified output algorithm blocks and block numbers in the current page. Connection error will be diagnosed by the system during configuration and compiling. Prompt for related error items will be given by the system in case of errors. Relative algorithm blocks include: analog input algorithm block PAI for interpage calling, analog output algorithm block PAO for interpage calling, digital input algorithm block PDI for interpage calling and digital output algorithm block PDO for interpage calling. For detailed use of these blocks, please refer to relative information in [LN2000 Algorithm Block Manual]. 3.6.3.4 Property Edition of Connection Algorithm Block between Stations Data transmission between stations is carried out by the algorithm blocks used for interstation switchover. The parameters to be called by other pages should be connected to the output ends (including digital and analog output ends) between pages. The input ends between pages are used to call values from other pages. The calling input ends between stations perform the parameters calling according to the station numbers and page numbers of specified output algorithm blocks and block numbers in the current page. Connection error will be diagnosed by the system during configuration and compiling. Prompt of Relative error items will be indicated by the system in case of errors. Relative algorithm blocks include: analog input algorithm block NAI for interpage calling, analog output algorithm block NAO for interpage calling, digital input algorithm block NDI for interpage calling and digital output algorithm block NDO for interpage calling. For detailed use of these blocks, please refer to relative information in [LN2000 Algorithm Block Manual]. 3.6.4 Jumping of Connection Algorithm Block between Pages The analog input ends and digital input ends used for interpage switchover should be respectively connected to analog output ends (PAI, PAO) and digital output ends (PDI, PDO) which are also used for interpage switchover. The page number and serial number in its page of the output end will be indicated on the input end algorithm block after the input end is connected to an output algorithm block. An identical figure as the output algorithm block will appear at the right side of the block showing the input end to be output. If the parameters of an output end are output to several input ends, then there will be several figures identical to the block on its right side indicating the input end to be output. It can jump between input ends and output ends via the Jump function. The item “Jump to calling” in the menu of “Edit” will be available if the selected algorithm block contains algorithm blocks used for switchover between pages. The jumping between algorithm blocks used for interpage transfer can be realized. If several algorithm blocks are selected, which are available for interpage switchover, a selection dialog box will pop up for selecting algorithm block for Jump operation (as shown in Figure3.6-4). When the value of an output end is to be output to several input ends, a dialog box will pop up for selecting target input end (as shown in Figure3.6-5).   Figure 3.6-4 Interpage Switchover (I)   Figure 3.6-5 Interpage Switchover (II) 3.7 Page Operation The items “Interpage switchover”, “Create New Page”, “Delete Page” and “Page Property” will show up when pulling down the item “Page operation” in the main menu. These items are also accessible by right clicking in the blank of client area to pop up a floating menu (shown in Figure3.7-1).   Figure 3.7-1 Right button floating menu during SAMA graphic configuration 3.7.1 Page Switchover   Figure 3.7-2 Dialog box of page switchover The dialog box of page switchover is shown on the right side of the screen similar to the dialog box of searching target algorithm block, which is not modal dialog box. The page switchover dialog box contains a page list where the page numbers and description of pages are displayed (as shown in Figure3.7-2). Interpage switchover can be easily performed by clicking target page in the list. Especially, because of the non-modal property, it is not necessary to close the page switchover dialog box during SAMA graphic configuration for more convenient operation. 3.7.2 Create New Page The dialog box of creating a new page is shown in Figure3.7-3. As opening the dialog box, a new page number will be given by the page number edit box and the number equals to the largest number plus 1. Note: new created page numbers can be modified but it will not be identical to existing numbers. Press the “Confirm” button after inputting page description and page operational cycle.   Figure 3.7-3 Dialog box of creating a new page 3.7.3 Delete Page The “Delete” function is always performed on the current page. An error dialog box will pop up when there is only one page during performing this function. Before deleting a page, prompting information will show up for confirmation (as shown in Figure3.7-4). After confirmation, all algorithm block in this page will be deleted as well.   Figure 3.7-4 Prompt information box of deleting a page 3.7.4 Page Property The page property dialog box is used to edit page description (as shown in Figure3.7-5).   Figure 3.7-5 Dialog box of page property 3.7.5 Zooming of Page There is a combo box on the tool bar. “100%” will be displayed in the box when the program starts indicating that the page is in normal size. Pull down the combo box, and the 5 options of “400%”, “200%”, “100%”, “50%” and “25%” will show up (shown in Figure3.7-6). The size of the page can be zoomed by selecting one of the options, and the size of the algorithm blocks will be changed at the same time. In addition, the page can be zoomed in any scale. Input proper number into the combo box and press key “enter”, and then the size of page will change as specified value. e.g., input “123.45” and press key “enter”, “123.45%” will be displayed in the combo box and the page is zoomed to 1.2345 times of the original size. Only digital input can be accepted in the combo box.   Figure 3.7-6 Zooming of pages 3.7.6 Text Label Tool There is a text label tool  on the left side of the page zooming combo box, which can be used to insert necessary text description on the position required to be labeled of the SAMA graphic. It is shown in Figure 3.7-7.   Figure 3.7-7 Text function block view 3.8 Compile When selecting the item “Compile” in the menu of “Compile”, the system will prompt whether perform total compiling or single station compiling as shown in Figure3.8-1. Compiling will start after confirmation. After compiling is finished, system will prompt successful compiling as shown in Figure3.8-2.   Figure 3.8-1 Dialog box of compiling property   Figure 3.8-2 prompt box of successful compiling 3.8.1 Function of Compiling After configuration of SAMA graphic, it is required to compile to check the error of SAMA configuration and create downloading files and files used for graphic configuration software. 3.8.2 Compiling Process Firstly, the connection between input and output function algorithm blocks and database points will be checked. If there is no connection, it will prompt error and an error prompt dialog box will pop up indicating the fault algorithm block. After confirmation by clicking, it will switchover to the page where the block is located, and the block will be automatically selected. It is very convenient to locate the fault algorithm block. Secondly, check the analog input ends and digital input ends used for interpage connection have been connected with relative output ends. If not, error prompt will show up and this situation will make the SAMA graphic incomplete. Finally check that the algorithm blocks to which the analog input ends and digital input ends used for interstation calling connect are the relative output ends. If not, error prompt will show up. After diagnosis, the relationship between algorithm blocks will be determined and these blocks will be sorted as per advanced control principle, and then the block information will be saved in files in accordance with the algorithm block operation sequence. 3.9 Commissioning and Online Parameter Modification 3.9.1 Commissioning Operation When initiating “StartUp”, the item “Commissioning Operation” in the menu of “Commissioning” will be available if “Online running” is selected, otherwise, this item will be gray and invalid. System will be in commissioning operation status when “Commissioning Operation” is selected as shown in Figure3.9-1. With the online commissioning function, online supervision of input and output data of blocks and online modification of block parameters can be realized. Then the current output value will be indicated on the output end of a block with the font in blue. In addition, connection lines for digital parameters are distinguished by different colors making the trend of a line more visible. Red line refers to “1” and blue line refers to “0”. When SAMA is online, the configuration parameters of a block in the master and standby station can be online modified by clicking the “Confirm” button in the algorithm block property dialog box. If the standby station is not initiated, prompt will be displayed for failed parameter modification of the standby station. The configuration parameters of master and standby station will be in discrepancy. The parameters should be copied from the master station to the standby station when the latter is in normal operation. Do not press the “confirm” button in the property dialog box, if not intend to modify parameters online. The modified SAMA graphics and parameter settings in offline status should be downloaded for operation (i.e. Only the modified parameters in commissioning status are available, modification in other cases should be recompiled and downloaded, otherwise the modification is invalid.).   Figure 3.9-1 “Right button floating menu” during online operation commissioning of SAMA graphic configuration 3.9.2 Online Parameter Modification of Algorithm Blocks The parameters of algorithm blocks can be online modified in commissioning operation status. Modify the parameters of the algorithm block by pop up of the property dialog box. After pressing the “Confirm” button in the dialog box, the modified parameters will be transmitted to the relative running master and standby stations. The process station will accept the modified parameters and operate according to these modified parameters. 3.9.3 Force and Retain the Output Value of an algorithm Block In commissioning operation status, the output values of algorithm blocks can be forced and retained. A floating menu will pop up when right clicking the algorithm block to be forced or retained (as shown in Figure3.9-1). There are two items for selection: [Force block output] and [Retain block output] while the items [Cancel output forcing] and [Cancel output retaining] are invalid. During commissioning operation, if a selected algorithm block has output, then the items [Force block output] and [Retain block output] are available. When item “Force block output” is selected, if the block has several output values, a dialog box will pop up for selecting items to be forced, and then a dialog box will pop up for setting value. When the output of block is in forced status, the color of the output font will be red and the color of the forced block will be pink as shown in Figure 3.9-2. When item “Retain block output” is selected, if the block has several output values, then a dialog box will pop up for selecting output value to be retained. When the output of block is in retained status, the color of output font will be green as shown in Figure3.9-3. If the outputs of forced block or retained block are set, the items [Cancel output forcing] and [Cancel output retaining] are available.      Figure 3.9-2 Schematic diagram of forced block output Figure 3.9-3 Schematic diagram of retained block output Force and cancel force function: when SAMA is online, the force function is available for forcing output setting of algorithm blocks. The force operation is valid for master and standby (in tracking status) stations. If the standby station is not initiated, prompt will be displayed for failed parameter modification of the standby station. The configuration parameters of master and standby stations will be in discrepancy. The parameters should be copied from the master station to the standby station when the latter is in normal operation.   4 Operating Instruction of Graphic Configuration Software 4.1 Function Description This application is used to draw monitoring graphics of the operator station.
