The field "Name" defines the name for the variable. Start address can be used to define an address in the I/
O area. In this way wanted overlays can be realized. The type of the variable will be set under "Variable
Type". The sorting help make easier to find the desired variable. Click "OK" to accept settings.
If the process image of the PLC program is loaded the signals can be mapped to the variables (double click
on the signal, see details in TwinCAT manual)
