Numeral Table Memory Data before Start of Operation
1, 2, 3... 1. Initial value inputs at the Support Tool are written into the numeral memory
table entries as 2-word signed binary data regardless of the Storage Type or
Number of Words settings. (Even when the value is written in hexadecimal
with the $ prefix, it will be displayed in decimal at the Support Tool after the
input is confirmed.)
2. Before operation starts, the contents of the numeral memory table entries
are retained within the PT as 2-word signed binary data regardless of the
Storage Type or Number of Words settings.
Numeral Table Memory Data at the Start of Operation
3. When operation is started, the contents of numeral memory table entries are
written to words in the host first. At this point, data is converted and written as
described below according to the Storage Type or Number of Words set-
tings.

Conversion and storage
BCD 1
The 2-word signed binary data is converted to BCD and
the least significant 4 digits are written. If the value is
negative, F and the least significant 3 digits are written.
BCD 2
The 2-word signed binary data is converted to BCD and
the 8 digits are written. If the value is negative, F and
the least significant 7 digits are written.
Binary 1
The least significant 4 digits of the 2-word signed binary
data are written as is.
Binary 2 The 2-word signed binary data is written as is.
4. After operation has started, the host words are read and the data is regularly
mirrored in the numeral memory table entries. The data is converted and
