    PG)对S7-300PLC编程。使用PG电缆将PG和CPU互连在一起。要通过PROFINET连接调试CPU或对其编程，也可以将编程设备通过以太网电缆连接到CPU的PROFINET端口。多个S7-300CPU通过PROFIBUS电缆彼此之间通信及与其它SIMATICS7PLC通信。多个S7-300通过PROFIBUS总线电缆连接在一起。S7-300模块的概述:组件功能插图装配导轨附件：屏蔽连接元件S7-300机架电源(PS)模块PS将线电压(120/230VAC)转换为24VDC操作电压，然后提供给S7-300及其24VDC负载电路。CPU附件：前连接器（CPU31xC）CPU执行用户程序，向S7-300背板总线提供5V电压，并通过MPI接口与MPI网络中的其它节点通信。特定CPU的附加功能：PROFIBUS子网上的DP主站或DP从站工艺功能点对点连接通过集成PROFINET接口进行以太网通信例如CPU31xC例如CPU312、314或315-2DP例如CPU317信号模块(SM)数字量输入模块数字量输出模块数字量输入/输出模块模拟量输入模块模拟量输出模块模拟量I/O模块附件：前连接器SM转换不同的过程信号电平，使其与S7-300相匹配。功能模块(FM)附件：前连接器FM执行对时间要求严格及占用内存较大的过程信号处理任务。例如定位或控制通信处理器(CP)附件：连接电缆CP将减轻CPU的通信任务。

    用于连接PROFIBUSDP的CP342-5DPSIMATICTOPconnect附件：带有带状电缆端子的前连接器模块为数字量模块接线接口模块(IM)附件：连接电缆IM将S7-300中的各排互连在一起。带总线连接器的PROFIBUS总线电缆将MPI或PROFIBUS子网的节点互连在一起。PG电缆将PG/PC连接到CPURS485中继器RS485诊断中继器中继器用于放大信号及连接MPI或PROFIBUS子网的各段。交换机交换器用于将以太网的各个节点互连在一起。带RJ45连接器的双绞线电缆。用于互连带有以太网接口的设备（例如，带有CPU317-2PN/DP的交换机）安装有STEP7软件包的编程设备(PG)或PC需要使用PG对S7-300进行组态、设置参数、编程和测试。读出服务数据:应用（适用于或更高版本的CPU）对于服务，例如，如果CPU发出状态信号“DEFECTIVE”（所有LED闪烁），您可以选择保存信息以分析CPU状态。此信息存储在诊断缓冲区及实际服务数据中。选择“目标系统->保存服务数据”(Targetsystem->Saveservicedata)命令读取该信息，并将数据保存到文件中以便转发给客户支持部门。如果CPU处于“DEFECTIVE”状态（所有LED闪烁）下，请关闭电源再打开（关闭/打开电源）。结果：CPU现在处于STOP模式。CPU转到“STOP”模式后。 变 频 器：MM420、 MM430、 MM440、 6SE70、 6RA70,V20，V60，V90系列。

     门子PLC前连接器是起接线端子的作用。西门子PLC模块上没有接外接信号线的接线端子，所以用专门的前连接器将外接信号线与模块上的信号线接起来，其实就是个接线端子排。西门子前连接器是干什么用的,使用带IO口的模块一定要使用前连接器吗，还是前连接器是为了接线方便而使用的。plc内部继电器之所以称为软继电器，是因为PLC内部有许多具有不同功能的器件，用于实现数据的传输运算处理存储。为了把这些元件(如输入继电器，输出继电器，定时器，计数器等等)与通常的物理元件区分开，所以将这些编程元件称为软元件。全新原装西门子编码器6FX2001-5FD25-1AA0连接器模块CPU处理器。静安区代理模块连接器6ES7532-5HF00-0ABO
