serial port on the control (terminal J1). To connect the terminal, slightly loosen

the right-hand screw in the cover over J1 and rotate the cover clockwise to

expose the 9-pin connector. Then firmly seat the connector on the terminal into

J1.

The programmer does a power-up self-test whenever it is plugged into the

control. When the self-test is complete, the screen will display two lines of

information. This is information relating to the application. Pressing the ID key will

change the display to show the part number of the software and version letter.

The programmer screen is a four-line, backlit LCD display. The display permits

you to look at two separate functions or menu items at the same time. Use the

UP/DOWN ARROW key to toggle between the two displayed items. The BKSP

and SPACE keys will scroll through the display to show the remainder of a

prompt if it is longer than the display screen's 18 characters.

The 723PLUS has two sets of menus—the Service menus and the Configure

menus. The Service menus allow easy access and tuning while the engine is

running. The Configure menus may be entered only if the I/O is shutdown (hence

the engine stopped).

Configure Menus

To access the Configure menus, the engine must be shut down. Press the  key.

The display will show, “To select configure, press enter”. Press the ENTER key

and the display will show, “To shutdown I/O, press enter”. Press the ENTER key

and this will allow you into the Configure menus.

To move between the menus use the LEFT ARROW and RIGHT ARROW keys.

To move through the set points within a menu, use the UP ARROW and DOWN

ARROW keys. Once within a menu, to return to the menu header, press the ESC

key.

To leave the Configure menus press the ESC key. The set points will be

automatically saved when leaving Configure.

Service Menus

To access the Service menus press the DOWN ARROW key. To move between

menus, and to move through set points within menus follow the instructions as

for the Configure menus. Also to return to return to the menu header, or to leave

Service, follow the Configure instructions.

Adjusting Set Points

To adjust a set point, use the TURTLE UP or the RABBIT UP keys to increase

the value, and the TURTLE or RABBIT DOWN keys to decrease the value. The

RABBIT UP and RABBIT DOWN keys will make the rate of change faster than

the TURTLE UP and TURTLE DOWN keys. This is useful during initial setup

where a value may need to be changed significantly. Where necessary, to select

TRUE, use either the TURTLE UP or the RABBIT UP keys, and to select FALSE,

use the TURTLE DOWN or RABBIT DOWN keys.

Use the + or – keys to change integer values in the application software.

To obtain an exact value, press the = key. Key in the required figure and press

ENTER.

view the variables for your 723PLUS control on a PC (personal computer). These

instructions are meant to be introductory only. Full on-line help is available in

each application. It is assumed that you already have Servlink and Watch

Window installed. The default installation location can be found by clicking the

START icon (Microsoft Windows 95 or later) on the main menu bar and then

clicking the PROGRAMS menu item. Look for an icon called WOODWARD

WATCH WINDOW.

Make sure that all other programs that may access your computer

communications port are shut down.

Get the right cable to talk from your PC to the control (5416-614 will work for

J2 and J3. 5416-870 for J1).

Start the Servlink server and open a new file. Select the proper COM port for

your PC, verify that POINT TO POINT communications mode is selected,

and verify that the baud rate matches the baud rate of the 723PLUS. The

default baud rate is 19 200. See the on-line help file if you have been

changing the port settings of your control.

Select OK. If everything is working right, you should see an animated picture

of a string of “1”s and “0”s flying from the control to the PC on your screen.

You now have a network definition file whose default name is NET1. You

should save this file as “your filename.NET” (use FILE/SAVE AS). Link this

name to your control part number, as it will work only with that application.

For instance, if the upper level control number is 9907-031. you could save

the file as 9907031.NET. DO NOT DISCONNECT THE SERVER.

In the Servlink window you will now have another dialog window titled “your

filename.net”. In this window you will see a ballhead icon and a control

identifier name. Unless you have given the control a serial number (or name)

with the SLSN.EXE program, this name will display as “”.

Start the Watch Window application. When Watch Window executes, you will

have a screen displaying three windows entitled Watch Window, Explorer,

and Inspector.

The Explorer window will have two groups displayed, SERVICE and

CONFIGURE. Double clicking on either of these will expand them to show

groups of values. Explorer is used only to locate a tunable or monitor value.

In order to change a value or monitor a value, you must drag and drop a

value from the Explorer window into the Inspector window.

Once a value is displayed in the Inspector, you can see several blocks of

information. The most important blocks for a tunable value are the FIELD and
