to a PC word, if it has not been displayed even once, it may be used at initializa-
tion only.
S Use of the "copy type"
Copy will not be executed when the "copy type" is other than "0" or "1". The
memory table copy is executed only when the contents of the area are
changed. To repeat copying of the same copy source and same copy destina-
tion, write a value other than "0" or "1" for the copy type, and then, write a cor-
rect value again.
S Copying a numeral memory table
If the display method or the number of registered words include discrepancies,
a numeral memory table may not be copied and displayed correctly.
This example gives a PC program to switch the character-string display on the
screen by using the memory table copy operation as the allocated bit is turned
ON and OFF.
