♦
Unlike with $SB19 in the system memory, a dialog box for the password to cancel the input prohibit
will not be displayed even if the screen is touched with input prohibited.
♦
The Touch Switch Lock Control Flag has priority if both $SB19 in the system memory and the Touch
Switch Lock Control Flag are used as input prohibit conditions.
♦
Entering the System Menu by pressing two corners of the screen (or by pressing any corner twice for
the NS15) is prohibited when input is prohibited using the Touch Switch Lock Control Flag.
3-10-3 Prohibiting and Allowing Input for Individual Functional Objects
Input to functional objects is controlled by control flags for functional objects on NS-series PTs that
accept input.
Method
1. When creating a screen using CX-Designer, select Control flag - Input - Indirect in the property
settings for each functional object and set the control flag address.
2. Input can be prohibited and allowed by changing the status of the specified control flag address.
Prohibiting input:
Change set address status from ON to OFF (1 → 0).
Allowing input:
Change set address status from OFF to ON (0 → 1).
