Changing Numeral and Character String Display
Section 8-5
Actually, a decimal point is set according to the “number of digits in integer part
and decimal fraction part” (page 360).
As shown in the table above, although the contents of a word are displayed as
they are for the combinations indicated below, the displayed numeric values are
different from the contents in other cases.
- Displaying the contents of the numeral memory table for which the “Storage
Type” is “BCD” in a numeric value for which “Display Type” is “decimal”.
- Displaying the contents of a numeral memory table for which “Storage Type” is
“binary” in a numeral for which “Display Type” is “hexadecimal”.
[Setting]
When creating a screen using the Support Tool, set the allocated word for the nu-
meral memory table. When making this setting, the “Words” and “Storage Type”
settings must be taken into careful consideration.
Reference: The range of numeral memory table numbers which can actually be used depends
on the number of numeral memory tables set for “Tools” – “PT Configuration” −
“System” setting at the Support Tool.
[Operation]
(1) Change the contents of the word in the host to which the numeral memory
table is allocated.
The contents of the word are reflected to the numeral memory table according
to the setting of the numeral memory table.
Note that the contents of a numeral memory table allocated word can only be
read out when the memory table is being used for an element that is currently
displayed by the NT31/NT31C (if the background function is set for a trend
graph, the contents of the corresponding word are always read out). The con-
tents of an allocated word which is not related to the display are not read out.
