Memory Tables and Bar Graphs
Section 5-2
By writing a negative number (whose most significant digit is “F”) to the allo-
cated word of a graph set as “Sign display “No””, the graph display will
become 0 % and the % display will show “
***
%”.
For the procedure to write numeral values to the allocated words of the
numeral memory table entries, refer to
5-2-1 Displaying the Contents of Allo-
cated Words of Memory Table Entries
(page 180).
For the procedure to change the contents of the numeral memory table entry
(PLC words), refer to
5-2-2 Changing Displayed Numerals or Character
Strings (Changing the Contents of Allocated Words ... Direct Specification)
on
page 182.
• Available Allocation Words
The numeral memory table entries can be allocated to the following PLC
areas:
❍
: OK
: 1 word only
×
: NG
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.
The range of respective area varies with the type of PLC.
Note
(1) LR 0000 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.
