西门子PLC PROFIBUS DP总线接头 ●为网络增加设备：在9600的波特率下。50米距离之内，一个网段最多可以连接32个设备，使用一个中继器允许在网络上增加32个设备。●在不同的网段之间电隔离：如果不同的网段具有不同的地电位，将他们隔离会提高网络的通讯质量。一个中继器在网络中被算作网段的一个节点，但没有被指定站地址。1．触点的安排 梯形图的触点应画在水平线上，不能画在垂直分支上。 2．串、并联的处理 在有几个串联回路相并联时，应将触点最多的那个串联回路放在梯形图最上面。在有几个并联回路相串联时，应将触点最多的并联回路放在梯形图的最左面。 3．线圈的安排 不能将触点画在线圈右边，只能在触点的右边接线圈。 4．不准双线圈输出 如果在同一程序中同一元件的线圈使用两次或多次，则称为双线圈输出。这时前面的输出无效，只有最后一次才有效，所以不应出现双线圈输出。5．重新编排电路 如果电路结构比较复杂，可重复使用一些触点画出它的等效电路，然后再进行编程就比较容易。 6．编程顺序 （2）数据对象 数据对象包括定时器、计数器、高速计数器、累加器、模拟量输入/输出。定时器类似于继电器电路中的时间继电器，但它的精度更高，定时精度分为lms，10ms和100ms三种，根据精度需要由编程者选用。定时器的数量根据CPU型号不同。计数器的计数脉冲由外部输入，计数脉冲的有效沿是输入脉冲的上升沿或下降沿，计数的方式有累加1和累减1两种方式。计数器的个数同各CPU的定时器个数。高速计数器与一般计数器不同之处在于，计数脉冲频率更高可达2kHz/7kHz，计数容量大，一般计数器为16位，而高速计数器为32位，一般计数器可读可写，而高速计数器一般只能作读操作。在S7-200CPU中有4个32位累加器，即AC0～AC3，用它可把参数传给子程序或任何带参数的指令和指令块。此外，PLC在响应外部或内部的中断请求而调用中断服务程序时，累加器中的数据是不会丢失的，即PLC会将其中的内容压入堆栈。因此，用户在中断服务程序中仍可使用这些累加器，待中断程序执行完返回时，将自动从堆栈中弹出原先的内容，以恢复中断前累加器的内容。但应注意，不能利用累加器作主程序和中断服务子程序之间的参数传递。模拟量输入/输出可实现模拟量的A/D和D/A转换，而PLC所处理的是其中的数字量。3．参数空间用于存放有关PLC组态参数的区域，如保护口令、PLC站地址、停电记忆保持区、软件滤波、强制操作的设定信息等，存贮器为EEPROM。在S7-200PLC中所处理数据有三种，即常数、数据存贮器中的数据和数据对象中的数据
