Numeral memory tables have the following properties.
Possible Settings
Property
Meaning
@ For BCD format:
−9999999 to 99999999
@ For binary format:
−2147483648 (80000000H) to 2147483647 (7FFFFFFH)
Value
The initial values that can be set as the contents of memory tables by the
Support Tool
The format is determined by the system memory of the NT31/NT31C and
the “Numeral Storage Type” setting (“Storage type and stored data”, page
287).
Check mark (initialize)/No check mark (do not initialize)
Initial
This setting determines whether or not the allocated words at the host are
initialized when the power to the NT31/NT31C is turned ON, when the
NT31/NT31C is reset, and on transition from the System Menu to the RUN
mode.
“Initialization” here means initialization of the allocated words at the host:
when a check mark is set, the previously existing numeral memory table
contents are written to the host words. When no check mark is set, the
data at the host is read and set in the numeral memory tables.
System/Binary/BCD
Storage
Type
Method for storing numeric data in numeral memory tables.
This setting is valid only when the numeral table is allocated to the host.
Numeral memory tables that are not allocated to the host always use
binary format. If a setting is made for “System”, it complied with the “Nu-
meral Storage Type” setting of PT configuration.
For details, refer to “Storage type and stored data” (page 287).
1/2
Words
The number of words used at the host when a numeral memory table is
allocated to the host.
For details, refer to “Allocated words” (page 286).
Any word address at the host
PC
Address
Word at the host to which the numeral memory table is allocated
When the numeral memory table is allocated to two words, designate the
first (lower) word.
For details, refer to “Allocated words” (page 286).
