The GOT can be connected to a general controller such as micro computer board.

(The connected controller is hereafter referred to as "host (unit)".)

• Outline

In genera-purpose communication, the host unit is connected to the GOT via the RS-232C

and functions as the parent station in communication. Inside the GOT, there is a data area

to hold word data and bit data. The host unit can read and write the data area using com-

munication commands.

The contents of display and control in the GOT are determined by the screen data created

using the screen creation software in the personal computer. The screen data specifies the

layout of objects displayed on the screen, and specifies actions to be performed by pressing

of touch keys.

The GOT is equipped with the function to display the word data in the form of numbers and

bar graphs, the function to access the data for changing the status of the bit data using

switches, etc.

The target of access is the data area inside the GOT. The data location to be accessed is

specified by the screen data.
