Numerals and character-strings can also be changed by copying between
memory tables: see "Copying the Memory Table" (page 208).
Either of the following two methods can be used to change the contents of the
display.
(1) Changing the memory table number to be displayed
(To change the contents of numeral memory table 41, in the following exam-
ple case)
(2) Changing the contents of the memory table used for display
(To change the contents of character-string memory table 39, in the follow-
ing example case)
In this section, the procedure for changing the display contents by using method
(1) is explained.
Method (2) involves changing the contents of the allocated table. For details, re-
fer to the sections on memory table copy (page 208) and changing displayed nu-
merals or character-strings (direct specification) (page 204).

This method is convenient when switching the display at the same location, for
example when monitoring a series of words, or when using unique codes to
specify individual character strings, etc.
cation of numeral/character display using the support tool. Set the number
(i.e., the number of words) of the numeral memory table to 1.
2. When creating the screen data with the support tool, register for the screen
the numeral memory table referenced in indirect specification. Set "Indrct"
for "Ref way".
For a character-string, specify the numeral memory table by using the "char-
acter display" function of the support tool.
For numerical values, specify the numeral memory table by using the "nu-
meral display" function of the support tool.
3. Using the "table edit" function of the support tool, write the data to be dis-
played to the memory table which is used for display. Use a numeral memory
table to display numerals and use a character-string memory table to display
character-strings.
4. Create a PC program to change the contents of the word allocated to the nu-
meral memory table which is used in indirect specification.
