Using sub-macros to do data operations

Using sub-macros to do data operations

Hello, welcome to the touch screen operation video tutorial, today to explain to you the use of sub-macros to do data operations, there are a variety of ways to do data operations, the first is to enable numerical operations directly in the digital format, to do some simple proportional conversion scaling function, the second can be converted by way of sub-macros, the third is the way you can directly use macro instructions, sub-macros compared to macro instructions, operation The sub-macro is a little easier to operate than the macro instruction, it can be converted by checking the box directly in the Enable Numerical Operations, you don't need to call it separately like a generic simulation. Click on the sub-macro management, you can directly open the sub-macro and edit it, you can also click on the sub-macro below the macro instruction, and then create a new macro instruction or edit the macro instruction, here you have added a macro instruction, directly edit it inside, there are two parameters, one is inputData, one is outputData, the inputData is as input data, the outputData is as input data. inputData is used as input data, outputData is used as output data after the operation, here to do a relatively simple operation, that is, the input value multiplied by three times and then output, after setting up click compile, compile success can be directly closed, according to the error error to modify, and then look at the number format has just been called to sub-macro. After setting up the direct click offline simulation, just set up the HMI display, and then multiply the function by 3, take a look, the left is not to do arithmetic, set up is 12, arithmetic multiplied by 3 times after the display is 36, the way to do data arithmetic with sub-macros is very simple, you can operate on their own. This is the end of the explanation of using sub-macros to do data operations, thank you for watching.
