Only one Text Alarm can be set to a single Base Screen. To display two or more Text Alarm Parts on one screen, use a Window Screen.
The maximum number of display characters on one row is decided by the display unit model and the text size.
If the Alarm Message is wider than the display area, the portion that exceeds the area is truncated and is not displayed.
When the Text File Number of the text displayed in the Text Alarm Part is changed during operation, the cursor and sub display are cleared.
When too many alarms arise simultaneously, you can place Text Alarm Parts on multiple screens and designate [Display Start Row] as follows to view the messages by changing screens.
Screen 1: Start Rung (normally "1")
Screen 2: Display Rows + Start Rung for 1 screen
Screen n: Display Rows x (n-1) + Start Rung for 1 screen
The Base Screen Number or Text File Number used for a sub display should be created in sequential numbers in the same order as the text rows to which Alarm Messages are registered.
The Base Screen and Text used for a Sub Display use screens equal to "(16 x Words to Monitor) + 1". These screens cannot be used for other purposes.
When the cursor is cleared during a sub display (the cursor is moved to the place outside of the display area, or the "End" switch is touched), the sub display is also be cleared.
The value of "the designated [Start Screen] + (Words to Monitor x 16)" is used as the Clear Base Screen Number or Clear Text File Number to clear the sub display.
For example, when the Start Screen is "100" and the Words to Monitor is "1", Screen Numbers 100 to 115 are used for the sub display screen and Screen Number 116 is used for the clearing screen.
When a sub screen is displayed with a Message Display [Text Display] and no clearing text is provided, the sub screen is cleared with [Clear Color] designated for the Message Display.
When a screen with a sub screen is changed, the sub screen is cleared. The display unit writes "0" to the designated word addresses of the Picture Display [State Display], Message Display [Text Display], and Window Part used for a Sub Display.
When [Start Screen] of the sub display is designated with [Address], do not change the Start Screen while the sub screen is displayed. This may interfere with proper sub display.
While a Sub Screen is displayed, communication time may increase.
