When the Set Bit Part is pressed, the Write address is turned ON. The state continues (i.e.

remains ON) even after release.
When the Set Bit Part is pressed, the Write address is turned OFF. The state continues (i.e.

remains OFF) even after release.
Every time the Set Bit Part is pressed, the Write address is complemented (ON
Toggle
Momentary* Only while the Set Bit Part is held down (pressed), is the Write address turned ON. Likewise,
when the switch is released, the Write address is turned OFF.
Note: DO NOT USE HMI MOMENTARY OPERATIONS FOR CRITICAL FUNCTIONS.
Communications failures between the HMI and the controller during a momentary operation
may cause the HMI to ignore touch release thus causing damage to machinery and operator.
Note: The state of the toggle switch shape/bitmap corresponds directly to the state of the read bit.
This is different from the Set Bit part, which only changes shape/bitmap when touched.
*Note: This software has three operation modes to handle momentary switch operations, based on the current value of
LW9044. Use an "initial set" SET WORD in the start up window to configure the desired operating mode. Operating Modes
are as follows:
0: Window popup is enabled during touch operations (down and up), when the touch is released (up) the BIT that was
previously set ON is set OFF even if the popup window hides the momentary switch. (Default Mode of operation)
1: Window popup is disabled during touch operations (down and up). This prevents popup windows from hiding
momentary switches.
2: Window popup is enabled during touch operations (down and up). If the momentary switch is hidden by a popup
window at the time touch release (up), the BIT is not reset.
Design Tips:
1. Use the same device address for read and write to have the Toggle Switch show the state of the device it is switching.
2. Use different Read and Write addresses for processes that need confirmation of state. Example: A motor start up might
need to be up to speed before operations can be performed. Use the Write address to start the motor and the Read
address as an indicator of when the motor is up to speed.
3. Disable Label tab, Tracking to place Labels at different locations on the switch.
