Setting/Displaying data according to digital switch input
Example 1: When setting the timer set (preset) values input from the digital switch
• The selection of the timer instruction number is performed using the input from the digital switches
(WX1). The timer preset (set) value can be input from the digit switches (WX0).
Example 2: When displaying the data in the programmable controller
• The elapsed value of the timer instruction is displayed on the 7-segment digital indicators (WY0).
The timer instruction number is selected by the input from the digital switch (WX1).

Each time R0 turns ON, the settings of the digital switches
[WX0 (BCD data)] are converted to binary data and stored in
the timer preset (set) value area specified by SV0 and IX.
The timer instruction number input from WX1 (BCD) is
converted to binary and stored in IX.
The timer preset (set) value input from WX0 (BCD) is converted
to binary and stored in the address specified by IX and SV0.
