6-2-5 Upgrading Bar Graphs

(Changing the Contents of Allocated Words)

Reference

Reference

The following describes the procedure to upgrade the bar graph display on the NT600S by changing the contents of the allocated words.

To change the bar graph display on the NT600S, change the contents of the PC ￿words to which the numeral memory tables have been allocated.

Available allocation words

The numeral memory tables can be allocated to the following PC areas:

Symbol	C Series PCs	Allocation		CV Series PCs		Allocation
DM	Data Memory	✓		Data Memory		✓
CH	Internal/Special Relay	✓		Internal/Special Relay		✓
TIM	Timer			Timer
CNT	Counter			Counter
HR	Holding Relay	✓		--
AR	Auxiliary Relay	✓		Auxiliary Relay		￿
LR	Link Relay	✓		--
			✓ : OK		: 1 word only	￿: NG

Since the special auxiliary relays of the CVM1/CV series PCs are allocated to the system, they cannot be used for purposes other than the system use.

The range of respective area varies with the type of PC. Refer to Appendix L PC Memory￿ Map (page 291).

The bar graph display cannot use hexadecimal numbers. If hexadecimal num- bers are set, the bar graph will not be displayed.

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 tables, refer to “Allocation Words and Display of the Memory Tables”

￿(page 167).

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 170, 172).
