[Character-string memory table display example]
To display the characters in order, allocate the characters as follows.
5-3-2
Changing Displayed Numerals or Character Strings
(Changing the Contents of Allocated Words....Direct
Specification)
The following describes the procedure to change displayed numerals or char-
acter-strings by changing the contents of the allocated words.Numerals and
character-strings can be changed also by making a copy of the memory table
entries. Refer to “Copying a memory table entry” explained later.
To change the numerals or character-strings displayed on the NT11, make
changes with the numeral or character-string memory table entry. To make
changes with the numeral or character-string memory table entry of the NT11,
change the contents of words by the PLC.
Reference
When it is necessary to display changing data such as monitored data of
words in the PLC, use the numeral and character-string memory tables. This
must be used to change the display contents (contents of memory table entry
or words).
Procedure
1.
Use the support tool to allocate the numeral and character-string memory
table entries to the PLC memory.
2.
Register the memory table entries for the numerals and character-strings
to be displayed when creating the screen data by using the support tool.
To display a character-string, use “character display” and specify the char-
acter-string memory table entry by using the support tool.
To display numerals, use “numeral display” and specify the numeral mem-
ory table entry by using the support tool.
3.
Create a PLC program to write the contents of numerals and character-
strings to be displayed on the NT11 to the PLC words.
Application Example of the Numeral Memory Table Entries Allocated to the PLC Words
This example gives the procedure to directly display the contents of the words
allocated as the numeral memory table entries in the PLC memory. The NT11
screen display will change as the contents of the PLC word change.
• Support tool settings
Allocate the memory as shown below by using the support tool.
Numeral memory table entry No. 1: DM0000 (allocated words: 2 words)
Numeral memory table entry No. 2: DM0002 (allocated words: 1 word)
