The following describes the procedure to change displayed numerals or character -strings by copying the contents of the memory table.

Reference Numerals and character-strings can be changed also by changing the contents of the allocated words. Refer to “Changing displayed numerals or character -strings” explained before.

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.

This procedure is convenient to switch predetermined values or character-strings according to the situation. By preparing several units of contents, various con- tents can be displayed by switching them to suit the situation.
