19.16 Display Screen Protect Function
19.16.7 Pointers for using the display screen protect function
The display screen protect function settings should be specified in a sequence program.
• The protect function is enabled by using the display module's "monitor/test function" to change the system
information's (system signal 1) "D +3" current value to "1" or "2".
• Once the setting is made, it cannot be canceled from the display module.
• To cancel the setting, use the programming tool to change the system information's (system signal 1)
"D +3" current value to a value other than "1" and "2".
If the system information's (system signal 1) "D +3" is set in a general purpose data register, however,
the display screen protect function can be canceled by turning the power off, then on again.
