depending upon the value of the PLC coil or register used in the Write address frame; however, this
does not mean that the object will continuously read the value of this address to determine the current
state. If you wish to do this, you must check the Read address frame and select the same PLC coil or
register as is used in the Write address frame.
6. Click the
Select
: checkbox, then select which
function key
(F1 thru F10, up, down, left or right) will be
assigned to the button object. Note: only one button object can be created per function key
assignment. If you use the Local Function Key Editor to configure a function key, then a button object
cannot be created for that key.
7. Configure each parameter for the particular type you are using (for more details consult the
Function
Key Type
section later in this chapter).
8. Click the
Frame:
pulldown box to select the type of
frame
that should appear around the object.
9. Click the
Font Size:
pulldown box to select the
size
of the text that will appear if you configure labels
(see the Show States Table button) for each state.
10. Click the
User Level:
to assign a
security level
for the object. If any security level is assigned other
than the default setting of 0, then the function key will display a password screen that requires the
operator to enter a (see Tools…User Level/Password Set menu) six-digit password before the
predefined action is performed.
11. Each function key can be configured to perform a secondary action known as the
Call Function
. The
Call
function allows the function key to set or reset a PLC coil,
in addition to the primary function that
was assigned to it
. For example, you can configure Function Key #1 to enter a value into a PLC
register whenever it is pressed by setting the
Type
: parameter to
Input Value
. By using the
Call
function, you can also have the key set or clear a PLC coil
before or after
a new value is entered into
the PLC register.
The Function Key Editors
There are two Function Key Editors, the Local and Global editors. The Function Key Editor configures each function key
without placing an object on the screen as is done with the Button Object. Use the button object (see above) when you wish
to have visual feedback that the function key has been ‘activated’ when pressed. The Global Function Key Editor is used to
configure how each function key behaves for every screen in which the Local Function Key Editor or Button Object have not
been used for that particular function key.
Using the Global Function Key Editor
The Global Function Key Editor configures a function key to do the following:
• Force On or Force Off a bit in the PLC
• Reset On or Off a bit in the PLC
• Configure a Function key to behave as a momentary switch
• Configure a Function key to behave as a push on/off switch
• Configure a multi-state function key
• Create the ability to edit a numeric register or place a constant value into a PLC register
• Act as an increment or decrement (Jog) key
• Display a new screen
• Enter a password
The Global Function Key Editor is used to configure how each function key will behave, regardless of which screen is
displayed; however, if a Button Object or a Local Function Key is configured for a particular screen, this setting will take
precedence over the setting in the Global Function Key.
