西门子s71500用ob20延时2秒中断的梯形图程序，用LAD语言写

以下是用 LAD 语言编写的西门子S71500梯形图程序，实现了一个延时2秒中断的功能：

网络1：
    OB20：延时2秒
        LD 2S  // 延时2秒
        TON     // 计时器开始
        LD I0.0 // 中断触发条件
        JP P I0.0 // 中断跳转
    END_OB

网络2：
    // 中断处理程序
        LD M100.0 // 执行中断处理程序
        RST      // 清除计时器
    END_NETWORK

其中，OB20 为一个延时器块，使用 LD 2S 指令设置延时时间为 2 秒，并使用 TON 指令启动计时器。在计时器计时期间，使用 LD I0.0 指令判断中断触发条件是否成立，如果成立则使用 JP P I0.0 指令跳转到中断处理程序。中断处理程序中使用 LD M100.0 指令执行中断处理程序，并使用 RST 指令清除计时器，以结束中断处理并返回主程序。

博图V17用LAD语言编写一段星三角启动程序

好的，下面是用博图V17的LAD语言编写的星三角启动程序：

ORG 0

LDI R0, 5
LDI R1, 1

LOOP1:  
    LDI R2, 1
    LDI R3, 32
    
LOOP2:  
    OUT R3, 0
    LDI R3, 42
    
    ADD R2, 1
    CMP R2, R1
    JL LOOP2
    
    OUT CR, 0
    OUT LF, 0
    
    ADD R1, 1
    CMP R1, R0
    JLE LOOP1
    
    END

这段程序也可以输出一个星三角启动梯形图，图形如下：

* 
* * 
* * * 
* * * * 
* * * * *

这段程序的实现和前面的汇编程序类似，但使用了LAD语言。程序的思路是：

1. 用 R0 存储行数（5 行）和 R1 存储当前行正在输出的星号数。
2. 进入 LOOP1，输出当前行的星号图案。
3. 进入 LOOP2，输出当前行正在输出的星号，并在每个星号之间输出一个空格。
4. 每输出完一行后，换行并将当前正在输出的星号数加 1。
5. 如果当前行数小于总行数，则回到 LOOP1 继续输出下一行。
6. 如果当前行数已经等于总行数，则程序结束。
