Details About Each Address - System Data Area

The following example describes one address communicating with a 16-bit device/PLC.

Stores the screen number that currently displays on the display unit.

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.

(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.

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.

The data type is Bin. 1 to 9999

The data type is [BCD]. 1 to 7999

To change screens from both the display unit and the device/PLC, set the [Reflect in Device/PLC] option from the System Settings, [Display Unit] page, [Display] area. When the [Reflect in Device/PLC] check box is cleared, screen change using LS0008 is not reflected to the mapped device/PLC's System Data Area [Change-To Screen] address. 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. (Enter the address that is the value of which 8000(h) is added to the screen number you want to display. ) 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.

Shows the screen when the value is "0h" and hides the screen when the value is "FFFFh". Values other than "0h" and "FFFFh" are reserved. When the screen display is hidden, the next touch on the screen will turn the display back ON.

Set as BCD. [Year] is the 2 digits of the year, [Month] is 2 digits from 01 to 12, [Day] is 2 digits from 01 to 31, [Time] is 2 digits for the hours from 00 to 23, and 2 digits for the minutes from 00 to 59 for a total of 4 digits. The defined clock data is written by switching the data write flag (LS0010, bit 15) from OFF to ON, or from ON to OFF.

For example, 2005, October 19, 21:57

  1. When data in the current Word Address "+10" is "0000"
    Month→Write "0010" to Word Address "+11"
    Day→Write "0019" to Word Address "+12"
    Time→Write "2157" to Word Address "+13"

  2. When you write "8005" to Word Address "+10," bit 15 of address "+10" turns ON, and clock data is rewritten. For "8005," bit 15 is turned ON by the "8000" portion, while the "Year" is set with "05". (Please write "0005" if bit 15 of the word address "+10" is already ON. Bit 15 will turn OFF, and the clock data will be written.)

Backlight OFF

When ON, the backlight turns OFF. When OFF, the backlight turns ON. (The parts placed on the screen function while the LCD is lit.)

  • Generally, when the screen is turned off, use Word Address "+9" (Screen Display ON/OFF).

  • With the GP4000 series (excluding the GP-4100 series, GP-4201TM and GP-4301TM), when the backlight is turned off (bit is turned ON), the display unit's status LED shows the breathing LED status.

  • When the logic program stops with the GP4000 series (excluding the GP-4100 series), bit is turned OFF.
