Memory Tables
Section 7-3
[Output Functions]
When a numeral memory table is allocated to a word or words at the host, the con-
tents of the numeral memory table are written to the word(s).
However, writing is only executed in the following cases.
S
When the contents of the numeral memory table have changed as a result of
operations at the NT31/NT31C, such as memory table copying by touch switch
operation, or use of the numeral setting function
S
When the “Initial” setting at the Support Tool is checked when the power to the
NT31/NT31C is turned ON, the NT31/NT31C is reset, or on transition from the
System Menu to the RUN mode (the contents of all numeral memory tables that
are allocated to the host and whose “Initial” setting is checked are written)
[Processing Functions]
The set “Value” (initial value) and the contents of the allocated word(s) at the host
are interpreted and stored in accordance with the set attributes (refer to “Common
Attributes”, page 285).

S
When an “analogue meter” is used, the contents of a numeral memory table can

graph.

When a “broken line graph” is used, the contents of multiple, consecutive numer-
al memory tables can be displayed in real time in the form of a broken line graph
(page 385).

memory table can be displayed in the form of a broken line graph (page 391).
S
When a “numeral setting” is used, numeric values can be input into the numeral
memory table from the screen of the NT31/NT31C (page 417).
S
When the touch switch copy setting function is used, the contents of a numeral
