Character and character elements

Hello, welcome to the touch screen operation video tutorial, this video we will talk about the use of numerical and character components. First of all, open the touch screen software Mochuan Studio, click on the components below the numerical and character display, numerical display, you can see the operational properties of numerical display, numerical input, character display and character input, the difference between numerical display and numerical input is that the former can only display can not write, the latter can display, can also write, and can be set to read and write different addresses can also be the same;; Character display and character input are operations on strings. Here we look at them separately, first look at the numerical input components, read address can be set by themselves, you can also use the label address way, click on the yellow label behind, enter the address label library, click on the new label, fill in the label name to set the address, then check the selection and exit, you can see the rate of change of the label here, the same we can also click on the drop-down list to select the address label If you want to change the address, you can change it directly in the address label library; click on the number format, you can see the data type, there are 16-bit signed numbers, 16-bit unsigned numbers, 32 signed numbers, 32 unsigned numbers, etc. The difference between signed and unsigned is that the former can display positive or negative numbers, the latter can only display positive numbers, the range of signed numbers can be seen in the familiar upper and lower limits, likewise If you select unsigned numbers, you can also see the upper and lower limits. 16-bit and 32-bit integers with decimal places are set to move a few decimal points to the left on top of the actual value, for example, if you set 1 decimal place here and set the value to 1234, the value displayed is 123.4, with the decimal point moved one place to the left; check the single precision floating point number and set the decimal place, which is to display a few decimal places on top of the current The following check box to enable numerical operations, the following can choose the proportional conversion, scaling, sub-macro operations, logical operations, shift mode, proportional conversion can be set by setting the maximum and minimum value of the proportion to convert the actual value and the relationship between the displayed value, the specific instructions can click on the description of the selection to view, for example, I set here is 0-9999, the minimum and maximum value of the proportion is 0 and 100, then the value of the display range is 0-100, the actual value is 0-9999, here you can click on the offline simulation to see, you can do a comparison, a do conversion, a do not do conversion. Next we look at the font, you can freely set the font size, type and colour, as well as the display and alignment, graphics can set the graphics of the components, dynamic graphics can set the movement of the components, communication settings are always valid by default, you can also set whether to participate in the communication through conditional settings, display settings is to control the display of the components, always valid by default, you can also set the conditions to The display setting is to control the display of the component, which is always valid by default, and can also be set by condition, to display when the condition is met, otherwise it is not displayed, here we have an additional control setting after checking the value input, it is possible to control the operation of the component, there is a confirmation before operation, after checking the box pops up before the operation, to confirm whether the operation is carried out, recording the operator operation can be done by matching the operation log to show when a certain user operated which device, the notification setting can be set in word, bit or trigger macro commands to operate, with pre-write and post-write. These can be set according to the actual situation. Let's look at the character display and character input elements. The character display and character input elements are the strings for operation. You can choose the encoding method according to the device or PLC. For strings we have to tick the ASCII keyboard, the font image and the settings behind it are the same as the numerical values, let's simulate it below, click on the offline simulation below the tool we will first look at the proportional conversion, LW10 is set to 9999, the corresponding value is 100, the data of LW10 is changed, the corresponding converted value is modified accordingly, then look at the strings, the number of strings exceeds If the number of strings exceeds the set number, the line will be changed, and this is the end of today's explanation.
