Now, to the frame we will add elements for displaying the values of the analog parameter for our four signals and the parameter of the complex object-tag ModBus.CM101.TE1314_1. To locate the display element of the analog signal on the mnemonic scheme we need to select it and then select the menu item "Widget"->"Library: Main"->"Analog show" in the menu of the window; after which the cursor will appear with the image of this element, which should be brought into the desired area of the mnemonic scheme and press the left mouse button. At the time of adding, a dialog will appear asking for the name of the new item. Similarly we will add five elements that we call: A1_Ti, A1_To, A2_Ti, A2_To and TE1314_1.
