5.6.1 Restrictions on Changing Models

• If you change from a high resolution display type to a low resolution display type, the data that exceeds the range is not displayed. If you change back to a high resolution display type, the data that exceeded the range is displayed.

• The maximum number of display characters on a part differs between a low resolution display type and a high resolution display type. If you change an alarm message created with a high resolution display type to a low resolution display type, any part that does not fall on the message screen is not displayed.

• When you change models, the screen data size may increase due to differences in hardware and function specifications. As a result, if the screen area capacity is exceeded or an error occurs, review the screen data and adjust the screen data size so it fits the screen area capacity.

• If you change from a model that supports port control to a model that does not support port control, all port control settings become open. For models that support port control, refer to the following. 1.5 Supported Features

• If you Convert Resolution, the part size, position, and the text size relative to the display resolution is adjusted automatically. Some scale magnification may not convert properly due to text size and resolution limitations.

• When using the [Call Screen] command to load a keypad set up from the [Common Settings] menu's [Keypad Registration], its size is not adjusted when running Convert Resolution. If required, set up the keypad again after changing the display unit model.
  Similarly, size adjustment does not occur for functions displayed in a special window, except for the Movie Player and Image Unit Window. Refer to the following for special windows.
  12.9 Displaying Multiple Windows on a Single Screen

• Available from the [System Settings], [Display Unit] in the [WinGP Settings] tab, the [Display Settings] do not change when you change IPC models. However, regardless of the IPC you are converting to, the [Specify Display Position] X and Y coordinates are initialized to 0 and the [Window Size] is initialized to XGA (1024x768) dimensions.

• When changing the model to a GP4000 series (except for GP-4201TM/GP-4301TM) or IPC series unit, in the [System Settings] [Display Unit] node's [Operation] tab, [Touch Panel Operation on Back Light Off Detection] option changes to [Enable].

• You cannot use the Font Area in the following models. When the project uses more than just fixed fonts and you change to one of the following display units, the screen area is used for the extra font information.

• GP-3200 Series

• GP-4100 Series (Monochrome Model)

• GP-4201TM and GP-4301TM

• ST3000 Series

• If the resolution, display color, or color levels differ when changing the display unit, the [Common Settings] menu's [Register Start Screen] settings will be deleted. However, if only the display colors are different when changing between SP5000 Series models (excluding Open Box), then the [Register Start Screen] settings are not deleted.

• When changing the model from SP5000 Series, GP4000 Series, LT4000 Series, ET6000 Series, ST6000 Series, STM6000 Series, STC6000 Series, or IPC Series to other models, the size of windows and the display position is corrected and displayed as follows.

• If the width is not in 4 pixel units, it is reduced to the 4 pixel unit closest in size.

• If the position of the X coordinate is not a 4 pixel unit, it will move left to the next closest 4 pixel unit on the X coordinate.

• When changing from a model with built-in I/O terminals to a model that with an external unit, the I/O driver also changes from an internal driver to an external driver. As a result, array element numbers of the following system variables are also replaced.

• #L_IOInfo

• #L_IOStatus

• #L_IOFault

Example:

When changing from AGP-*****-CA1M (with built-in I/O terminal) to SP5000 series (with an external unit), #L_IOInfo changes from #L_IOInfo[1] to #L_IOInfo[2].

#L_IOInfo[1]: Internal Driver 1

#L_IOInfo[2]: External Driver 1

For more information about system variables, please see the following.
