14 PLC Help Function
14.37 Direct Screen Selection

14.37.3 Precautions

(1) The operation when the screen selection requirement while executing some processing on the screen is as same as
when the key where the screen transition is generated (ex. function key) is pressed. Examples are shown below.
(a) File editing on the Edit screen:
The screen transits after confirming save.
(b) Inputting/Outputting:
The screen transits at once. Input/Output is operated on the background at this time.
(c) During buffer correction:
The screen transits at once. The content during buffer correction is not saved.
(d) During operation search:
The screen transits after finishing operation search.
(2) If the screen transition cannot be performed, no specific error is displayed or set, and the selection completion data
(R356) remains to be "1". Therefore, if there is no change over 2 seconds after the screen selection request (R356 = 1),
set it to "0" with the PLC. However, when the application software which requests the direct screen selection cannot be
found, R356 will be set to "8".
(3) The transition to the screen where the password input is necessary to display is possible only when the password is input.
(4) If you made the setting of displaying the previously opened screen for a Customization screen, the last displayed screen
will be displayed when the screen is moved to the Customization screen by designating the function No.
(5) When DIRECT_SCREEN of config.ini is "1", the following cautions are required:
(a) When the screen is displayed by designating the window No,, close all the windows which are currently displayed.
(b) While the modal window is displayed, the screen transition with the direct screen selection function cannot be per-
formed.
(c) The screen or window is not notified of the key events that are exclusive for screen transition or screen (window) dis-
play.
(d) On the Customization screen side, the direct screen selection function cannot be suppressed.

14.37.4 Restrictions

 This signal is used only for the transition to the Monitor, Setup, Edit, Diagnosis and Maintenance screens or any Customi-
zation screens. No screen transition is performed for a Customization screen of the executable file registration method.
 When a target main menu designation or window No. designation is not processed, the sub menu or the window No. is not
designated.
 When a Customization menu is designated to the target main menu, the sub menu is not designated.
When a Customization menu is designated, the sub menu should designate "0".
However, the window can be switched by designating the window No. when the NC Designer interpreter method/compila-
tion method Customization window is displayed by the menu designation.
 When transition to the same window screen is executed, the target window screen is shut once, and is displayed again.
 The direct screen selection function displaying "NCDesigner interpreter method" screen by the Customization cannot corre-
spond because there is no macro for the notification to a designated window.
 The menu No. (R358) setting by the direct screen selection switches the screen for the menu configuration when the menu
selection parameter "#11032" is set to "0" or "1". Therefore, the screen may be switched to the screen which is not intended
by MTB.
 When F0 screen is designated, the Customization screen is always displayed regardless of the on-board ON parameter
(#6451).
 While NAVI Mill/Lathe is being displayed, the screen transition may not be executed depending on the operation status.
