*1 WinGP does not operate. #H_Status_USBUsing is in the OFF state at all times. When #H_Control_USBDetachTrigger is turned ON, nothing operates.
The operation to insert and remove a USB storage device is as follows.
When you connect a USB storage device to the display, #H_Status_USBUsing is ON.
When you remove a USB storage device, turn ON #H_Control_USBDetachTrigger.
When the USB storage device can be removed, #H_Status_USBUsing turns OFF automatically.
When #H_Control_USBDetachTrigger is ON while writing the data from the USB storage device, #H_Status_USBUsing does not turn OFF until data writing is complete.

When #H_Status_USBUsing is OFF, you cannot access the USB storage device. Remove the USB storage device and insert again.

Do not transfer to offline mode, transfer data to the display, or insert and remove the USB storage device while writing data to the USB storage. This may result in an incomplete file or damage to the USB storage device.

*2 For writing security data, refer to the following.
#H_SecurityWriteControl

*3 If an error occurs immediately after a screen change, each animation operates as follows.
Visibility Animation:
Invisible Position/Rotation Animation:
Displayed on the position set during animation Color Animation: Displayed in the color set for the value when Word Address or the "Numeric Value" condition is selected, or displayed in the OFF color when Bit Address or the "ON/OFF" condition is selected.
If an error occurs after displaying on the front layer, the display state is maintained, but due to the drawings of other parts, it may be partially or completely erased.
