Chapter 6: Ladder Monitor Display
6-1 Outline of ladder monitor display
- On a normal display screen, put on an overlap screen. The LCD control terminal displays a ladder
monitor on the display area of this overlapped screen.
- By entering a coil number using the numeric keys on the screen, a ladder monitor can be displayed on
the overlapped screen. (Inputting TMR/CNT number is also available.)
Touch a lamp on the error status screen. Display a ladder chart on the overlap screen
6-2 Instruction to display ladder monitors
A ladder monitor screen can be displayed by the following methods.
Arrange a switch (setting a lamp memory) on the screen. By touching this switch, the LCD control
terminal searches a ladder circuit of one network having the coil number of this lamp memory, and
displays a ladder monitor on the overlap screen.
Enter any coil number (or TMR/CNT number) using the numeric key input screen, the LCD control
terminal searches a ladder circuit of one network having this coil number, and displays a ladder moni-
tor on the overlapped screen.
An application example
- Linking with relay mode (message display), the LCD control terminal searches a ladder circuit of
one network having this coil number, and displays the ladder monitor on the overlapped screen.
- Display a ladder monitor by assigning any memory of a switch.
Once a ladder chart is displayed, touch (1st time) a contact point on the ladder chart. The cursor moves to
the touched contact point and displays one line of symbol/comment below the ladder chart if a comment
is registered.
Again touch the cursor (2nd time); the LCD control terminal searches a coil for this contact point.
If the coil exists, the LCD control terminal displays a ladder chart having this coil.
If the coil does not exist, the LCD control terminal displays a "NETWORK NOT FOUND" message.
6-3 Ladder monitor display style
When displaying a ladder monitor, the control terminal uses its display style and call overlap.
"Call overlap" is to set one overlap screen. By setting this, the same overlap screen can be displayed on
any screen.
On the call overlap screen used, a contact point switch is arranged (translucent) for executing coil search
by pressing the contact point on the ladder chart.
