4. After operation has started, the host words are read and the data is regularly
mirrored in the numeral memory tables. The data is converted and written as
described below according to the Storage Type or Number of Words set-
tings.

Resume Function and Initial Values
When the resume function is not used, the preset initial values are written in the
numeral memory tables when the power to the PT is turned ON, the PT is reset,
or the PT is switched to RUN mode from the System Menu. (See Initialize be-
low.)
Use the resume function to prevent initialization and retain the last values that
were in place before operation stopped.
Resume function setting
Yes
No
The System Menu's initialize operation can be used to write the initial values to
the memory tables regardless of the resume function setting. When the resume
function is used, the previous values will be used even if the initial values are
changed, so changes to the initial values won't be reflected in the tables. Initial-
ize the memory table values before starting operation to reflect changes in initial
values.
Initialize
The initialize setting determines whether the contents of numeral memory tables
are written to the allocated word(s) in the host when the power to the PT is turned
ON, when the PT is reset, or the PT is switched to RUN mode from the System
Menu.
Here, initialize means the initialization of the contents of host word(s) as they are
overwritten by the contents of the numeral memory table. If the numeral memory
table is not allocated to a host word or words, this setting has no effect.
Conversion and storage
The least significant 4 digits of the 2-word signed binary
data are written as is.
The 2-word signed binary data is written as is.
Conversion and storage
The contents of the host words are treated as 4-digit
BCD, converted to 2-word signed binary data, and
stored. (If the most significant digit is F. the remaining
data is treated as negative 3-digit BCD.)
Words that do not contain 4-digit BCD or F and 3 BCD
digits are invalid and the numeral memory tables will be
left unchanged.
The contents of the host words are treated as 8-digit
BCD, converted to 2-word signed binary data, and
stored. (If the most significant digit is F. the remaining
data is treated as negative 7-digit BCD.)
Two-word fields that do not contain 8-digit BCD or F
and 7 BCD digits, are invalid and the numeral memory
tables will be left unchanged.
The contents of the host words are treated as signed
binary data (a sign bit and 15 data bits), converted to
2-word signed binary data, and stored.
The contents of the host words are treated as signed
binary data (a sign bit and 31 data bits) and stored as
is.
Numeral memory table contents
The previous numeral memory table values are used.
The numeral memory table's initial values are used.
