5-2-4 Upgrading Bar Graphs
(Changing the Contents of Allocated Words)
The following describes the procedure to upgrade the bar graph display on the
NT11S by changing the contents of the allocated words.
To change the bar graph display on the NT11S, change the contents of the PC
words to which the numeral memory tables have been allocated.
S
Available allocation words
The numeral memory tables can be allocated to the following PC areas:
Symbol Area Name Allocation
DM Data Memory
f
CH Internal/Special Relay
f
TIM Timer
CNT Counter
HR Holding Relay
f
AR Auxiliary Relay
f
LR Link Relay
f
f
: OK : 1 word only
×
: NG
The range of respective area varies with the type of PC. Refer to Appendix H PC
Memory Map (page 160).
The bar graph display cannot use hexadecimal numbers. If hexadecimal numbers
are set, the bar graph will not be displayed.
By writing a negative number (whose most significant digit is “F”) to the allocated
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 tables, refer to “Allocation Words and Display of the Memory Tables”
(page 108).
For the procedure to change the contents of the numeral memory table (PC
words), refer to “Changing Displayed Numerals or Character Strings (Changing
the Contents of Allocated Words)” (page 111).
