Memory Tables and Graphs

S Direct Specification
S Indirect specification
Only direct specification can be used as the access method for graphs and nu-
meral settings.
- Direct specification (numeral display property Indirect Specification is set to
OFF)
- Indirect specification (numeral display property Indirect Specification is set to
ON)
Direct specification is a method of specification in which the contents of dis-
played memory table entries are directly correlated with the contents of the al-
located words.
Indirect specification is a method whereby the contents (numeric value) of the
specified numeral memory table entry are taken as the number of a numeral
memory table entry, and the contents of the numeral memory table entry with
that number are displayed.
A combined total 50 of numeral displays and character string displays can be
specified on one screen by using indirect specification.
This specification method is a little complex, but it allows the display to be
changed more easily according to the circumstances. In the example above, if
1 were added to the contents of memory table entry 18 to give 52, the contents
of memory table entry 63 would be displayed instead.
The memory table entries used for display can also be allocated to areas in the
PC, so that the display can also be changed in response to changes in the data
to be displayed (i.e., the contents of character string memory table entry 62 in
the example above).
However, in comparison with direct specification, indirect specification re-
quires more time for processing.
