The GOT can be used as an electronic operation panel in which all functions carried out on
conventional operation panels can be done on a monitor screen, including switch operations,
lamp displays, data display, and message displays.
Other functions which can be done with the
GOT
are circuit monitoring of the PC CPU, monitoring and
changing device data, and monitoring and changing the buffer memory
of
the special functions module.

Use
of free-location touch keys
Touch keys can be freely positioned at any location, in
1
-dot units. In addition, the mini-
mum module for the key size is the width of one full-width character (1 6 dots
x
16 dots).
This gives the user greater freedom in creating monitor screens.
GOT
CPU
contains a 32-bit
RISC*'
chip
The GOT contains a 32-bit RISC chip, which is used in combination with a 32-bit local bus
for high-speed processing. This significantly reduces the amount of time required to switch
monitor screens, refresh data displays, and for touch keys to respond.
