The 16-bit BIN value from 0 to 9999 is stored in D+1. For the sake of convenience, the following description is displayed in BCD conversion. 6142 + 6143 +When the instruction input is ON, the ARWS instruction will operate as shown below 6144 + 6145 +[[image:file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml3320\wps3.png]][[image:1758526599000-920.png]] 6146 + 6147 +Display and operation part of the content 6148 + 6149 +[[image:file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml3320\wps4.png]][[image:1758526656501-227.png]] 6150 + 6151 +1. The digit specification of n displayed by the 7-segment digital tube with BCD code 6152 + 6153 +A 4-digit (10^^3^^ digit) is used as an example in the following operation description, . 6154 + 6155 +The action of the digit selection switch (S+2, S+3) 6156 + 6157 +1. The action when input S+2 with reduced digits is ON.Each time the switch is pressed, the number of digits specification is changed according to 10^^3^^ →10^^2^^ →10^^1^^ →10^^0^^ →10^^3.^^ 6158 +1. The action when the input S+3 with increased digits is ON. Each time the switch is pressed, the number of digits specification is changed according to 10^^3 ^^→ 10^^0 ^^→ 10^^1 ^^→ 10^^2 ^^→ 10^^3^^. 6159 + 6160 +1. The action of the LED for displaying the selected digits (D2+4 to D2+7). The specified number of digits can be displayed by LED by strobe signal D2+4 to D2+7. 6161 +1. The operation of the data change switch in units of digits (S, S+1). The data is changed for the number of digits specified by the "digit selection switch" above. 6162 + 6163 +1. Increase the action when the input is ON. Each time the switch is pressed, the content of D1 changes according to 0→1→2→...→8→9→0→1. 6164 +1. Reduce the action when the input is ON. Each time the switch is pressed, the content of D1 changes according to 0→9→8→7...1→0→9. 6165 + 6166 +These contents can be displayed in the 7-segment digital tube display. 6167 + 6168 +As shown above, through a series of operations, you can write the target value into D1 while viewing the 7-segment display. 6169 + 6170 +**✎Note:** 6171 + 6172 +* The setting of parameter n 6173 + 6174 +Please refer to the parameter setting of SEGL (FNC 74) instruction. The setting range is 0 to 3. 6175 + 6176 +* The output format of the programmable controller, please use a transistor output type programmable controller. 6177 +* About scan time (operation cycle) and display timing 6178 +* The ARWS instruction is executed synchronously with the scan time (operation cycle) of the programmable controller. 6179 +* In order to perform a series of displays, the scan time of the programmable controller needs to exceed 10ms. 6180 +* When it is less than 10ms, please use the constant scan mode and run with a scan time longer than 10ms. 6181 +* Number of occupied points of the device 6182 + 6183 +1. The input of the device s occupies 4 points. 6184 +1. The output of the device d2 occupies 8 points. 6185 + 6186 +* Restrictions on the times of the uses of instructions 6187 + 6188 +Only one ARWS instruction can be used in the program. 6189 + 6190 +**Error code** 6191 + 6192 +|**Error code**|**Content** 6193 +|4084H|The data input in the application instruction (d1) and (d2) exceeds the specified range 6194 +|4085H|The output result of the read application instruction (s), (d1) and (d2) exceeds the device range 6195 +|4086H|The output result of the write application instruction (d1) and (d2) exceeds the device range 6196 + 6197 +**Example** 6198 + 6199 +[[image:file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml3320\wps5.jpg]] 6200 + 6201 +The corresponding hardware wiring is shown in the figure below, and the PLC should be transistor output type: 6202 + 6203 +[[image:file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml3320\wps6.jpg]] 6204 + 6205 +(1) The digital tube in the figure shows the value of D0. Press X10 to X13 to modify the value. The value of D0 can only be between 0 and 9999. 6206 + 6207 +(2) When X20 is ON, the cursor position is thousands. Each time the back key (X12) is pressed, the specified position is switched in the order of "thousands → hundred → ten → pieces → thousand"; if the forward key (X13) is pressed, the switching sequence is reversed; the cursor position is determined by the strobe pulse signal (YO04 to YOO7) LED indication of connection. 6208 + 6209 +(3) For the cursor position, each time you press the increment key (X11), the content of the position changes by 0 → 1→ 2→……8→9→0→1, and when you press the decrement key (X10), press 0 →9→8→7→…… 1→0→9 changes, the modified value takes effect immediately.
