4 Screen Creation

z Test function
The display effect of the created screen can be checked by the NB-Designer itself through the offline
simulation without need to connect it to the PLC. Select [Tools] - [Compile] from the main menu.
After the successful compilation, select [Tools] - [Offline Simulation] and then right-click the mouse
to select “close” to exit from the simulation. Please note that it needs to be recompiled and then
simulated each time when the setting or project is changed.
The offline simulation is convenient for users to preview the screen effect visually without need to
download programs to the HMI, thus enhancing the programming efficiency substantially, but the
offline simulation can only show the display effect of the project screen. Because this project
involves the data sampling and input/output control of PLC, the actual operating effect can be seen
only after the edited project being downloaded into HMI for operation and the communication with
PLC being established. If the user just wants to see the created screen effect, it needs to place one
Number Input component in the Common Window with the address of LW0 (for example), and then
add the same address into the PLC Control component with the Control Type of “Change Window”
in the PLC Control dialog box. In this case, each created window can be seen after the number of 10
to 17 input into the Number Input component during the offline simulation. Later, it just needs to
delete the Number Input component and the added control conditions after the correct confirmation.
Please refer to 3-14 Simulation in the NB-Designer Operation Manual for details on simulation.
