Displaying and Referencing Numeral Memory Table Contents
Memory Tables and Bar Graphs
Reference: The only method available for numeral memory tables used for graphs and numer-
Since the numeral memory tables can be allocated to the words in the PC, the PC
can write data to the numeral memory tables or the initial values can be set when
creating the screen data.
Also, by relating the numeral memory tables with the bar graphs, the bar graphs
corresponding to the data of the numeral memory tables can be displayed.
During the operation, the display contents are automatically updated so that the
contents of the numeral memory table being displayed are the same as that of the
PC word.
There are two methods for referencing numeral memory tables used for numeral
displays, as follows:
al settings is direct specification.
S Direct specification
Direct specification is a method of specification in which the contents of displayed
memory tables are directly correlated with the contents of the allocated words.
S Indirect specification (with Ver.5 direct connection only)
In indirect specification, the contents (numerical value) of the specified numeral
memory table are regarded as a memory table number and the contents of the
table with this number are displayed.
Up to 50 numeral displays and 50 character string displays can be specified on one
screen by using indirect specification.
