For the trigger bit's ON/OFF, leave an interval longer than the communication cycle time*1 or display scan time*2, whichever is longer.
After you turn ON the Trigger Bit Address, if a screen change occurs before the drawing or erasing is complete, the Trigger Bit Address does not turn OFF.
The only graphic data that can be stored is Bin data. BCD data cannot be used.
If the graphical data to be stored is outside the range, it will default to zero.
For coordinate data, the top-left of the screen is coordinate (0, 0). For graphics in a window, the top-left of the screen registered as a window is coordinate (0, 0).
For the color attribute's background color, if you designate "Black + Medium Speed Blink" or color code 255, the background color will become transparent.
The following shows actions which occur immediately after a screen is changed or power is turned ON.

O: Operation is performed immediately after the screen is changed, or the power is turned ON.
X: Operation is not performed immediately after the screen is changed, or the power is turned ON.
*1 The Communication Cycle Time is the time it takes from the point the display unit requests data until the display unit receives data from the device. It is stored in internal device LS2037 in Bin format. The unit is 10 milliseconds. There is an error of +/-10 milliseconds.
When using multiple devices/PLCs, you can each the communication cycle time of each device/PLC from the [System Settings] [Peripheral List] page's [List of Device/PLC Management Addresses].

*2 Display Scan Time is the time required to process one screen. It is stored in internal device LS2036 in Bin format. The unit is in milliseconds. There is an error of +/-10 milliseconds.
