S Program operation
(1) When the numeral setting strobe flag (IR/CIO 11211) comes ON (1), the con-
tents of IR/CIO 0111 (the word where the content upgrade memory table
entry is located) are transferred to DM 0105. The number of the numeral
memory table entry that contains the upgraded data is stored in DM 0105 (in
this case it is 0003 or 0004).
If the numeral memory table entry is allocated to a PC word, the value input
to it can be read easily by accessing the allocated word.
In this case, the contents of numeral memory table entry No. 3 are stored in
DM 0005 and the contents of numeral memory table entry No. 4 are stored in
DM 0006.
