Application Example This example shows the reading of the numeral memory table entry number
after a value has been changed by inputting numerical data at the NT11.
• Setting at the support tool
Make the following settings using the support tool.
Allocated word for the PT status notify area: CIO/IR 0110
Numeral memory table entry No.3: DM 0005 (saved word: One)
Numeral memory table entry No.4: DM 0006 (saved word: One)
Data registered for the screens:
Numeral setting 1 ... Reference table entry “numeral memory table en-
try No. 3”
Numeral setting 2 ... Reference table entry “numeral memory table en-
try No. 4”
• PLC program
Create the following PLC ladder program.
• Program operation
1. When the numeral setting strobe flag (bit 11211) comes ON (1), the con-
tents of CIO/IR 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 003 or 004).
If the numeral memory table entry is allocated to a PLC word, the value in-
put to it can be read easily by referring to 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.
