Special internal relay (M)/special relay (SM)
These are internal relays (M) with determined applications in the PLC.
A variety of information can be viewed, including PLC CPU information and MELSEC
information.
QCPU and QnACPU have dedicated SM devices.
With the ACPU, these are M9000- .
Status display bar
The status display bar is the bottom line of the GT Designer2 display. It displays guidance,
cursor information, position information, etc.
STN
STN (Super Twisted Nematic) liquid crystal
A simple matrix type LCD that seals liquid crystals between multiple transparent electrodes
lined up vertically and horizontally and that displays the desired image by applying signal
voltage to the electrodes to control the liquid crystal array state at the intersections. Pixels are
switched ON/OFF by twisting liquid crystal molecules and by aligning them into straight lines.
The GOT1000 can display 256 colors or 16 tones of monochrome (black and white).
System information
This function transmits the GOT status (screen number being displayed, error number, etc.) to
the PLC, and outputs information (GOT error resets etc.) from the PLC to the GOT. This
function is set to a word device.
A read device reads information to the GOT.
A write device writes information from the GOT.
T
Template
Templates are for easily saving and reading figures and objects.
Text file
This is a file containing only letters, numbers, and symbols.
A comment can be output to a text file, edited with an editor, and the edited file can be input.
Since object settings and other GOT screen information can be output to a text file with the
print function, it is also possible to read this file into a word processor and create an original
document.
TFT
A color liquid crystal display using TFTs (Thin Film Transistors)
Thin-film transistors are laid out at the intersection of transparent electrodes lined up vertically
and horizontally. This is an active-matrix type of LCD in which the liquid crystal is driven by
these thin-film transistors so laid out.
The response is fast. For color display, there are three TFTs for each pixel, and the light from
each TFT is passed through a red, green, or blue color filter.
Compared to simple matrix LCDs, there is no tendency to low contrast, and the number of
scanning lines can be increased, and intermediate tone expression is also easy, so this type
of LCD can display with high quality. On the other hand, the structure is complex, resulting in
high cost.
On the GOT1000, display is 256 colors/ 65536 colors.
