A bit button can be configured to perform the following operations:
|
Operation
|
Description |
|
Set ON |
Sets the specified bit to On when the button is pressed. |
|
Set OFF |
Sets the specified bit to Off when the button is
pressed. |
|
Set ON Pulse |
Sets the specified bit to On when the button is pressed
and then sets the bit to Off to generate a positive
pulse with the specified pulse width. |
|
Set OFF Pulse |
Sets the specified bit to Off when the button is pressed
and then sets the bit to On to generate a negative pulse
with the specified pulse width. |
|
Momentary ON |
Sets the specified bit to On when the button is pressed
and sets the bit to Off when the button is released.
Note: Pressing and releasing a momentary button
quickly might generate a pulse that is too short to be
detected by the controller. To avoid this problem,
specify a sufficient minimum pulse width for the
operation; so the setting of the bit to Off is delayed
if necessary to generate a pulse that is always
detectable. |
|
Momentary OFF |
Sets the specified bit to Off when the button is pressed
and sets the bit to On when the button is released.
Note: See the note above. |
|
Invert |
Inverts the state of the specified bit when the button
is pressed.
|
Note: You can configure a bit button to
operate a bit of a word or a bit of a double-word. In
these instances, you need to specify the number of the
bit to be operated.
