When creating the screen data by using the Support Tool, make the following
settings for each numbered character string:
• Initialization Setting
Set whether or not the PLC words are initialized with the character-string
memory table initial value registered to the screen data memory when the
main power supply is turned ON or reset.
• Number of Registration Words
Set the number of words within 16 words required for registering the char-
acter-string data. One word can store two normal-size characters.
• Setting the Words for the Character-string Memory Table Entries
The character-string memory table entries can be allocated to the following
PLC words. Set the word type and the first word.

Since the AR area bits of the CVM1/CV-series PLCs are allocated to the sys-
tem, they cannot be used for purposes other than the system use.
If the "number of registration words x 2" ("word setting window") set with the
Support Tool is larger than the "number of character digits" ("character-string
display setting" window), the character string may be broken halfway.
(1) LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
(2) The EM Area is supported only by the C200HX/HG/HE-(Z)E PLCs.
Since the numeral memory table entries can be allocated to the words in the
PLC, the PLC can write data to the numeral memory table entries or the initial
values can be set when creating the screen data.
