How do wincc oa success stories contribute to its market reputation?Well, these success stories are like proof of its quality. When other companies see that it has been successful in various projects, they are more likely to trust it. For example, if a big manufacturing company had a great experience with wincc oa in streamlining their production line, other similar companies will take notice. It also gives an idea of the support and functionality that comes with the product.
Animation in winccThere are many ways to create animations in WinCC. The following are some common situations:
** 1. Picture switching animation (using the button to switch pictures as an example)**
1. ** Object and Attribute Setting **
- The screen was composed of several "objects", such as buttons and screen windows. The button was a "window object", and the image window was a smart object. The image to be displayed in the image window is specified by the Image Name in its Attributes.
- For the button, you need to set up a mouse action event for it. For example, when the left mouse button is clicked, the corresponding picture name will be transferred to the "picture name" attribute of the picture window, thereby realizing the picture switching.
2. ** Configures the action of the screen switching button (button event configuration)**
- Take switching to a specific screen (such as "Screen 1.pdd") as an example. According to a certain step, the mouse action event will be set and the screen name will be passed to the "Screen Name" attribute of the screen window. The other buttons used to switch the screen (such as button 2, button 3, etc.) had a similar configuration.
3. ** Configures the default display image of the image window (static and dynamic attributes of the object)**
- In order to display the default image in the image window after WinCC starts, you need to specify a default image name (static attribute) in the "image window" attribute. By default, the picture window would display a static specified picture. When the button event was triggered, the corresponding picture would be displayed.
** 2. Simple graphic animation (such as water flow animation)**
1. ** Drawing and Basic Setting **
- For example, to make a water pipe animation, first draw the pipe, and at the same time draw a line chart inside the pipe to represent the water flow path.
- Choose the line chart to adjust the global color scheme, select the line color, and adjust the line width and line type.
2. ** Code editing to achieve dynamic effects **
- He selected the broken line to edit the VPS action and realized the dynamic effect by writing code. For example, the code could define variables and set their attributes, such as changing the actual coordinates of the line to make the line move, and setting boundary conditions, such as reset when the actual coordinates exceeded a certain value.
** 3. Animation related to the custom object (Take the pop-up panel of the custom object as an example)**
1. ** Setting of custom object parameters **
- The custom object could define many parameters. For example, after setting the corresponding parameters, the pop-up panel could be set according to the pop-up position of the pop-up screen and the size of the pop-up window.
2. ** Writing Script Code **
- In the script code, for example, in the "Sub OnClick(Byval Item)" section, by obtaining the name of the parent object's screen and other operations, set the location, size, loading screen name, pop-up window name, title name, and other attributes of the pop-up panel, and finally make the pop-up panel visible. There were also parts like "Function Text_Trigger(ByVal Item)" that implemented specific functions, such as setting ITEM.TEXT. to be equal to a certain value.
** 4. Animation of the status of the associated equipment (Take the image of the touch screen associated with the PC as an example)**
1. ** Setting of the program of the PC **
- Set up relevant programs in the programming of the PC, such as the start-stop program, the self-adding program, and so on. In order to make the value change fast enough, the system clock memory can be enabled (if M0.0(10HZ pulse clock) is selected as the condition for counting).
2. ** Touch screen configuration screen **
- To add a new device (such as the TP1200 touch screen) to Boto, first set up different status screens (such as four different fan status screens), establish a graph list and associate the corresponding values and graphs. Then, he would set up the start and stop buttons and the response state (such as the circle that responded to the start and stop state according to the filling color), and associate them with the variables of the PC. Pay attention to adjust the collection period of the HMI-related variables to an appropriate value (such as adjusting from 1S to 100MS) to avoid the image being stuck. Finally, the simulation was carried out. First, it simulated the operation of the PC program, and then started the simulation of the touch screen. The associated animation effects (such as the color change of the circle, the switching of the fan state, etc.) could be seen.

How to read and write txts in winccYou can read and write txts in WinCC in the following ways:
** 1. export WinCC variables to a TEXTS file (write operation)**
1. Using VBScript:
- First, create an object instance of `Scripting.FilesystemObject`, for example:
- `Dim fso,File`,`Set fso = CreateObject("Scripting.FileSystemObject")`。
- The path and name of the file to be written can be determined by reading the relevant WinCC variables (such as `HMIRuntime.Tags("" Files Name).Read`) to determine the file name. Assuming that the obtained file name is stored in the variable `a`, then open the file in the write mode (`ForWriting = 2`), such as `Set File = fso.
- Then, you can write the values of the WinCC variables into a file one by one, for example,`File.WriteLine(HMIRuntime.Tags("Var_1").read)`, etc., to write the values of multiple variables.
- Finally, close the file `File.Close` and give a prompt message such as `MsgBox "The file has been successfully imported/ExportSuccessful"`.
** 2. Read the data from the TMT file to the WinCC variable (Read Operation)**
1. Using the same VBScript script:
- First, create an object instance of `Scripting.FilesystemObject`, such as `Set fso = Create Object ("Scripting.Filesystemobject")`.
- Read the relevant WinCC variable (such as `HMIRuntime.Tags("BrightName").Read`) to determine the path and name of the file to be read (assuming it is stored in the variable `a`), and then check if the file exists, such as `If fso. Filexists ("D: ""Export&""CStr(a)"".txt;) Then`.
- If the file exists, open the file `Set txtfile = fso. Open Text ("D: "";";";;;";;;";";;;;"";"";"& quot
- Then, read the contents of the file line by line and write them into the corresponding WinCC variable, such as `HMIRuntime. Tags'("Var_1").Write txtfile.
