Memory Tables and Bar Graphs
Procedure 1. Set the PC area for allocation of the numeral memory table to be referenced in
172
indirect specification using the support tool.
2. When using the support tool to create screen data, register on the screen the
numeral memory table referenced in indirect specification. Specify the "indi-
rect" option for the reference method.
In the case of a character string, use the "character display" function of the
support tool to specify the numeral memory table.
In the case of a numerical value, use the "numeral display" function of the sup-
port tool to specify the numeral memory table.
3. Use the "table edit" function of the support tool to write the actually displayed
data to the memory table for display. If displaying a numerical value, use a nu-
meral memory table and if displaying a character string use a character string
memory table.
4. Create a PC program to change the contents of the word allocated to the nu-
meral memory table referenced in the indirect specification.
S Notes on writing memory table numbers
When writing the number of the memory table for display to the numeral memory
table referenced in indirect specification, always specify it in BCD. Also, be sure
to specify a number within the range of memory table numbers that actually exist
(0 to 127).
If the contents of the numeral memory table for indirect specification are speci-
fied in hexadecimal format, or the number specified is outside the valid range for
memory table numbers, the display is not updated.
S Notes on writing character strings
The points to note when displaying character strings are the same as those de-
scribed for direct specification. See "Important points when writing a character
string" (page 149).
