Write a memory table number etc. to the copy memory table setting area in the PT
status control area in the PC memory. Data will be copied between the memory
tables in the NT600S and the displayed value will change accordingly.

according to the situation. By preparing several units of contents, various con-
tents can be displayed by switching them to suit the situation.
