Numeric data is displayed by placing fields on a screen that reference PLC memory locations. Up to six numeric fields can be placed on a single screen. Bit status can be displayed on the screen using bit controlled text.
It is recommended that programming steps be performed by accessing the Windows menu items at the top of the program window. Deactivate the Tool Station (the Desktop cartoon image) by selecting Options menu, Tool Station. The tool station should disappear.
A dialog will appear that allows additional PLC models to be added to the PLC selection menu. Make sure that the PLC needed for the project is included in the list on the right.
(If the incorrect NT2S model is selected, the project can be converted at anytime using the file conversion utility located on the Project menu, and select Model type. Just open the project and select this menu item and select OK.) Version 1.03...
RTC Download Time (NT2S-SF121B-E only) – Enter the time interval for downloading the RTC tags to the PLC here. The values range from 0 to 600 ( seconds ). 0 means the values will be downloaded as fast as possible. Any other interval will mean that NT2S will wait for the specific time interval before downloading the value into the PLC.
7. TAG DATABASE Once the project has been created, the very first step should be to define the TAG DATABASE. The tag database is a list of names (tags) that reference PLC registers or coils (bits). When programming screens, reference is made to this tag database. Users can choose to reference the tags either by name or PLC address.

7. Select ADD button to complete the creation of the register tag. CREATE A COIL A tag can reference a bit in PLC memory, called a coil. Use the following steps to create a tag for a coil: 1. Select Tag Database from the Edit menu.
New Screen. 3. Four different types of screens can be selected from the New Screen dialog: Normal, Link, Special, and Function. The following sections will discuss each type of screen. Choose a screen type, enter a screen number, and select OK to launch the Editing Screen dialog.
PRINT – Selection box that allows the NT2S screen data to print out the top serial port. MIN TIME – A minimum time can be assigned to assure an operator can view the screen. If a number is entered in this field, screens will display for the specified minimum time.

Multiple Bit Text elements can be placed on a single NT2S screen. The program will allow up to 32 single character bit text messages per screen. It is also possible to have one of the states, On or Off, to have no text displayed.

TAG, type, and format. Once the register is assigned and formatted, select OK. Text placeholders will appear in the display window at the cursor location. These placeholders can be positioned by adding characters before the placeholders.

Bits can be controlled in several ways. Turn Off and Turn On functions force set the bit to the 0 or 1 position. Toggle alternates the bit between 1 and 0 as the function key is pressed. Hold Off and Hold On set the bit to a 0 or a 1 as long as the function key is held (momentary switch).
10. LINK SCREEN A link screen is a parent screen on which a series of child screens can be displayed. The link screen is assigned a screen number which can be called by the Screen Trigger Register (STR). When the link screen number is in the STR, the NEXT(F1) and PREV(F2) function keys can be used to navigate through the list of specified child screens.
Enter key. The right most digit will begin blinking. Increment to the digit to the desired value and press the left arrow to shift it over. Increase the digits and shift them to the left until the desired number is displayed. Then press enter again to accept the value.

After selecting OK on the Edit Action Field screen, the Editing Screen dialog will appear. The previous dialog defined the Action Field. Insert the Action Field on to the NT2S screen by clicking on the ACTION FIELD HERE button on the lower right. Enter text to complete this screen.
PERFORM ACTION ON button. Once the action is set, you may choose to enter text in the text window at the upper left. If text is entered here, a message will be displayed when that function key is pressed. If the field is left blank, the screen will not change from the current screen.

There are two ways to edit a programmed function key screen. Use the Function Keys selection on the Edit menu item to access the Function Key editing dialog above. Or, click on the screen number, F0#, as it appears in the SCREENS dialog, as highlighted below.
HOLD ON – If the bit is ON, there will be no change to the bit. If the bit is OFF the display performs a FORCE SET of that bit when the key is pressed and a FORCE RESET when released. No other bits in that register are affected HOLD OFF –...
Type the second line as it should appear on the NT2S display. If the characters need to be centered on the second line, click on the first character of the second line with the mouse button and add spaces using the keyboard.
