Examples of Actual Applications of Memory Link

Screen switch is executed by writing the screen number to the first word in PT con-
trol area.
In this example, screen is switched from screen No.10 to screen No.15.
“000F” is specified in the example above since it is necessary to specify data of
written word in PT memory write command in binary.
If “Yes” is set for the “Response” memory switch for the communication setting of
memory link, the response indicated below is returned from PT after sending com-
mand. (If “No” is set, no responses will be returned.)

When the numeral was input on PT, “numeral input notify command” (sent from PT
to host) is issued from the PT. At the host, numeral data was taken out and pro-
cessed, then it is written to the PT by the “numeral memory table write command”
(sent from host to PT).
