The upper 1-byte is the loop number currently displayed and the lower 1-byte is a command to change the loop
number. The display loop of LD512H can be changed by writing a command (1 to 8) in this area (1W). When you
write a value of 1 to 8, it is not necessary to mask the upper byte. In addition, a command to change the loop
number to LD512H is made only once when the value of the loop number command changes. It is not necessary to
change the value back to "0".
Note 1: This item is valid for LC511,512 System Program V2.20 or later and only when used in the LC511,512 and
LD512H firmware V2.2 or later.
