Reference: If the “Words” settings differ between the memory tables (copy source and copy
destination tables), numerals or character strings are copied correctly since 2
words are secured for a numeral memory table and 20 words for a character string
memory table in the NT31/NT31C. If the memory table is allocated to a word in the
host, however, copying may not be executed correctly if the “Words” settings differ
between the memory tables (copy source and copy destination tables).
[Setting]
The PT status control area must be allocated to a word in the host, accordingly, no
special settings are required for copying the data between memory tables.
