Next we need to carry out the operation known to us from the previous section, that is — establishment of connections to the previously created controller parameters. To do this we will open the tab "Links" (Fig.5.2.5) of the dialogue of editing the properties of the mnemonic scheme, where we will see the tree with the elements "A1_Ti", "A1_To", "A2_Ti" and "A2_To". Expanding any of the elements we will see the "Parameter" branch in which we have to specify or select the address in the item "pVal" of the values of our attributes "Ti" and "To", respectively. In the process of filling the elements, some of the properties must be specified as constants:
- "pName" — "val:AT101_1 Ti".
