Operation Options of Objects

The following table explains operation options which can be added to an object to make it more informative, secure, and useful.

Terminology

Definition
Enabling and disabling the touch operation The touch operation can be enabled and disabled either by a specified bit or by the current user level. You can choose to display the touch operation disabled sign on the button when the touch operation is disabled.

If the touch operation is to be enabled by a bit, you need to specify that bit and the bit value that enables the touch operation.

If the touch operation is to be enabled by the current user level, you need to specify the lowest user level that is required to enable the touch operation.

Select and set this feature in the Advanced page of the Bit Button dialog box.
Requiring the minimum hold time The touch operation will not be activated until the button is pressed and held down for the specified Minimum Hold Time.

Select and set this feature in the Advanced page of the Bit Button dialog box.
Requiring the operator confirmation A confirmation dialog box is displayed when the button is activated for setting a bit. The button will proceed to set that bit if the operator selects “Yes” to confirm the operation. The touch operation will be cancelled if the operator selects “No” to reject the operation or if the operator does not respond within the Maximum Waiting Time.

This feature is available for the following operations:
Set ON, Set OFF, Set ON Pulse, Set OFF Pulse, and Invert.

Select and set this feature in the Advanced page of the Bit Button dialog box.
Notifying a bit of the touch operation The notification is performed after the touch operation is done. You need to specify the bit to be notified and the bit value to be used for the notification.

Select and set this feature in the Advanced page of the Bit Button dialog box.
Logging the touch operations The time and date when the touch operation occurs, the new value that is written to the bit, and the predefined text can be recorded in the operation log with this feature.

Select and set this feature in the Advanced page of the Bit Button dialog box.
Change User Level The current user level can be changed when one of the following objects is activated to perform its function.

Bit Button, Toggle Switch, Word Button, Function Button, Screen Button, Numeric Entry, and Character Entry.


Select and set this feature in the Advanced page of the above objects' dialog box.
Designated Keypad The following objects can use the independent keypad for the entry of numbers or characters instead of using the custom keypad or the built-in keypad.

Numeric Entry, Advanced Numeric Display, Character Entry and Word Button.


Select and set this feature in the Advanced page of the above objects' dialog box.
Showing and hiding an object The visibility of an object can be controlled either by a specified bit or by the current user level, i.e. an object can be shown and hidden dynamically by any of these two methods.

If visibility is to be controlled by a bit, you need to specify that bit and the bit value that shows the object.

If visibility is to be controlled by the current user level, you need to specify the lowest user level that is required to show the visibility.

Note 1: When an object is invisible, the touch operation is automatically disabled.
Note 2: It is allowed to simply set an object as invisible. The touch operation is still enabled with this setting.
Select and set this feature on the Visibility page of the object setting dialog box.
