This shows the contents of write data in each address of the System Data Area.
Use [#MEMLINK]0012 (display screen ON/OFF) to hide the screen display. Do not use [#MEMLINK]LS0011 bit 0 (bit for turning off the backlight) to hide the screen display. Although the screen display disappears because the backlight is off, there is a risk for operation error since touch operation is still enabled.
When using the IPC Series or SP5000 Series Open Box, you cannot use the Backlight OFF and screen display ON/OFF features.

Details About Each Address - System Data Area
Reserved
Addresses "0", "2", "9", and "14" are reserved.
Because they are used by the display unit, please do not write data to these addresses. It may not work properly.
Monitor only the necessary bits. Reserved bits are sometimes used for display unit system maintenance, so do NOT turn them ON/OFF.

Display ON/OFF (0: ON, 1: OFF) |
This can detect if the display unit screen display is ON or OFF from the device/PLC. This bit changes in the following cases. (1) When FFFFh is written to the System Data Area's Display ON/OFF, the display turns OFF. (2) When the standby time passes, the display turns OFF (3) If the screen changes or is touched after the display turns OFF, the display turns back ON.

When an error occurs in the display unit, the corresponding bit turns ON. After the bit turns ON and the power turns OFF, the status is maintained until the GP changes from offline mode back to active mode.
Because the addresses are used for system control, do not display them by means of a Data Display.

Whatever the value, it will be stored in BCD, in top bits 0 to 7.
[Year] is the 2 digits of the year, [Month] is 2 digits from 01 to 12, [Day] is 2 digits from 01 to 31, [Hour] is 2 digits from 00 to 23, and [Minute] is 2 digits from 00 to 59.
For example, 2005, October 19, 21:57
Year→Write "0005" to Word Address "4"
Month→Write "0010" to Word Address "5"
Day→Write "0019" to Word Address "6"
Hours→Write "0021" to Word Address "7"
Minutes→Write "0057" to Word Address "8"
When using IPC Series or SP5000 Series Open Box, setting up the clock will update WinGP and the unit together.
If writing to a Word Switch (16 bit), when you take your finger off the Switch, the bottom 8 bits are output as an interrupt code. (Control code "FFh" is not output.)
Do not write control codes in the "00 to 1F" range. It can cause a communication interruption.
Write to this address in bit units. In some cases, writing with word data can change the value.
"Reserved" bits are sometimes used for maintenance of the display unit system. Turn them OFF.

Shows the screen when the value is "0000h" and hides the screen when the value is "FFFFh". Do not use any values except "0000h" or "FFFFh". If you touch the screen while the screen is hidden ("FFFFh" is set), although touch operations such as switches do not operate, the screen reappears ("0000h" is set).
Because the addresses are used for system control, do not display them by means of a Data Display.
Because the addresses are controlled in Words, you cannot write Bits.
When you write "FFFFh," the displayed screen disappears momentarily. If you want the screen display to disappear for the standby mode time designated in the display unit offline mode's initial settings, write "0000h."
On the following models, when the screen display is turned off (FFFFh), the display unit's status LED changes as follows.
Breathing LED
SP5000 Series
GP4000 Series (excluding GP-4100 Series, GP-4201TM, GP-4301TM)
Flashes in green every 5 seconds

When the logic program is terminated on the following models, stores "0h".

If you write using a Word Switch (16 bit), on touch the bottom 8 bits are output from the display unit to the host as an interrupt code.
Do not write control codes in the "00 to 1F" range. It can cause a communication interruption.
Because the addresses are used for system control, do not display them by means of a Data Display.
Because the addresses are controlled in Words, you cannot write Bits.
When you write data with a Word Switch (16 bit), they are output as interrupt data. If you have the host retrieve this byte of interrupt output (with the INPUT$ in BASIC, for example), and you can simplify the program by using the retrieved interrupt output to jump to each subroutine.
Set the Change-to Screen Number. The setup range differs depending on the [Data Type of Display Screen Numbers] option, available from the [System Settings], [Display Unit] link, in the [Display] tab's [Screen Settings] area.
Data type is Bin: 1...9999
Data type is BCD: 1...7999
To use direct access and memory link methods together, from the [System Settings] window click [Display Unit], and in the [Display] tab select the [Reflect in Device/PLC] check box.
If the [Reflect in Device/PLC] is not set, the screen change using the memory link method will be disabled because even if you write a screen number to the address "0015" using memory link method, the value will be changed to LS0008 by communicating using direct access method right away. In addition, screen change using LS0008 is not reflected to the mapped device/PLC's System Data Area [Change-To Screen]. As a result, screen changes may not be available from the device/PLC. (Unable to return to the screen before switching)
If you are not setting the [Reflect in Device/PLC] option, design the system to clear the change screen number to zero after screens are changed.
There is a method to change screens by force when you cannot change screens from the device/PLC side.
Turn ON the top bit (forced screen change bit) in the mapped device/PLC's System Data Area [Change-To Screen] address, and use the other bits to define the change to screen number. (In other words, enter the screen number you want to display plus 8000(h) in the address.) While the force screen change bit is ON, you cannot use touch operations to change screens. However, you can use the system variable #H_ChangeScreenNo to change screens.
Because the addresses are used for system control, do not display them by means of a Data Display.
Because the addresses are controlled in Words, you cannot write Bits.
When the screen is changed using the device/PLC's [Change-To Screen] address, the screen change number is reflected in LS0008 regardless of the [Reflect in Device/PLC] setting.
