Bar Graphs Section 4-5
4-5 Bar Graphs
The contents of the numeral memory tables of the NT20S can be displayed as bar
graphs as well as numeral data.
This section describes the bar graphs which can be displayed.
In order to change the data displayed in a bar graph, the contents of its numeral
memory table have to be changed.
For details on how to update the data of a currently displayed bar graph, refer to
“Upgrading Bar Graphs (Changing the Contents of Allocated Words)” on page
177, and “4-digit Write Numeral Memory Table” on page 206.
4-5-1 Bar Graph Functions
The bar graph function displays a value in a bar graph form as a percentage to the
specified value according to the contents of a numeral memory table. Up to 50 bar
graphs can be registered in one screen.
S
Reference table
The numeral memory table used as the reference for the bar graph display can
be set.
The support tool has the “direct” and “indirect” options for the reference method
of the numeral memory table. However, the NT20S recognizes the “direct” meth-
od only.
The bar graph display cannot use hexadecimal numbers. If hexadecimal num-
bers are set in the reference numeral memory table, the bar graph cannot be
displayed. Use caution not to write hexadecimal numbers except the minus sign
“F” to the reference numeral memory table.
Bar Graph Attributes The following attributes can be set with the NT20S for the bar graph display:
S
Position and size
