S Program operation
(1) When the numeral setting strobe flag (bit 11211) comes ON (1), the contents
of CH-0111 (the word where the content upgrade memory table is located) are
transferred to DM 0105. The number of the numeral memory table that con-
tains the upgraded data is stored in DM 0105 (in this case it is 0003 or 0004).
If the numeral memory table is allocated to a PC word, the value input to it can
be read easily by referring to the allocated word.
In this case, the contents of numeral memory table #3 are stored in DM 0005
and the contents of numeral table #4 are stored in DM 0006.
