All data corresponding to the data structure below should be read out.Example of an Electronic-Key structureThe data on the Electronic-Key are structured as follows:Byte no. Description Type Length Explanation103 – 104 KEYCRC CRC 2 bytes Checksum over a certain part of the Electronic-Key as copy protection.Refer to the EKM manual for details about the CRC.105 – 112Expiry date Date 8 bytes Electronic-Key expiry date.113 – 114 Authorization level Word 2 bytes Authorization level for access to the machine.115 Department Byte 1 byte Number describing a limited quantity of machines or installations.116 – 123 KeyID KeyID 8 bytes The KeyID is a number that is permanently pre-programmed on theElectronic-Key by EUCHNER. This number is different for each Electron-ic-Key. This number can be used to identify workers.The structure corresponds to application example AP000169-2…Setting the EKS Electronic-Key adapterProfibus addressThe device must be set to address 75. Address 75 is 1001011 in binary notation. DIP switches 1 to 7 are set accordingly (DIP switch 1 is the least significant bit).Figure 1Write-protection settingThe device is configured only for reading. Correspondingly, DIP switch 8 is set to ON.Figure 2Configuration in the control systemHardwareSimatic Manager version 5.5+SP1 is used for configuration. To perform parameter assignment for EKS on the Profibus, drag the object “EKS-A-IDX-G01-ST09/03” to the Profibus, followed by the “Read/Write: 32 Byte” module to the first slot. The address range can remain set at 256 to 287. The size of 32 bytes is selected because a total of 21 bytes of user data, including the KeyID, are to be retrieved. An adequately large input range must be reserved in the control system for this purpose.When a new Electronic-Key is inserted, the data are always read automatically from byte 0. As the user data are located at the end of the Electronic-Key instead of at the start in this example, the actual user data are loaded in a read routine in the sequential pro-gram. The KeyID is retrieved at the same time.Figure 3Set address 75 in the properties for the Profinet interface of the DP slave, matching the settings on the DIP switches. You set the subnet parameters according to your bus system.Figure 3Programming in the control systemGlobal data blocksData blocks are created for saving the transmitted and received data for the EKS.The data are created in a structured manner in data block DB1 for reading, with all data items longer than one byte being created as individual bytes to circumvent the even-numbered alignment in the control system. The data block must be the same length as the input range of the EKS, otherwise the system function for reading will not work.DB1, ReadBufferEKSFigure 4As a command has to be sent to the EKS so that the data from byte No. 103 and the KeyID can be read, the data required for this purpose are located at the start of data block DB2. The same data range of the EKS Electronic-Key is always read. The data block is suitably pre-filled during initialization. These are the bytes WriteCommand (64(dec.)), WriteStartAddress (103(dec.)) and WriteNumberBytes (21(dec.)). The data block must be the same length as the output range of the EKS, otherwise the system func-tion for writing will not work.DB2, WriteBufferEKSFigure 5DB10, instance module for FB1As the function module FB1 operates with static variables, a DB must be used as an instance module. In the example, DB10 is created for this purpose.STL program for retrieving the Electronic-Key contentThe reading program is programmed in FB1 in this example. The program reads only when an Electronic-Key is inserted and new data are ready. An Electronic-Key that has been read in once will not be read in again. The data from byte 103 (KeyCRC), including the KeyID, are read and are provided in data block DB1 from byte 4 for further processing. 21 bytes of user data in total are re-trieved from the EKS Electronic-Key.The status bytes of the EKS are saved in bytes 0 to 3 of DB1.Description of the interfaceInput dataNone.Output dataError message, new Electronic-Key and status of the DP slave.Input/output dataNone.Static dataThe counter value of the EKS is created statically. This value is compared with the value read by the EKS. Data are retrieved only if both values differ.Temporary dataNone.Changed registersA1, A2, SWUnchanged registersAR1, AR2, DBR1, DBR2System functions usedSFC14, DPRD_DAT – read standard DP slaves/PROFINET IO devicesSFC15, DPWR_DAT – write standard DP slaves/PROFINET IO devicesGlobal dataData blocks DB1 and DB2 with a minimum size of 32 bytes each are assumed.The content of data block DB1 is completely overwritten.The first three bytes (command byte, EKS address and length of the user data) are overwritten in data block DB2.Symbol tableFigure 8STL program in FB1- ReadEKS//Check of whether EKS is ready.

Only with the appropriate qualification is it possible to integrate the introduced example into a complete safety chain.The example represents only part of a complete safety chain and does not fulfill any safety function on its own. In order to fulfill a safety function, the energy switch-off function for the hazard location and the software within the safety evaluation must also be considered, for example.The introduced applications are only examples for solving certain safety tasks for protecting safety doors. The examples cannot be comprehensive due to the application-dependent and individual protection goals within a machine/installation.If questions concerning this example remain open, please contact us directly.In accordance with Machinery Directive 2006/42/EC, the design engineer of a machine or installation is obligated to perform a risk assessment and take measures to reduce the risk. When doing this, the engineer must comply with the applicable national and international standards. Standards generally represent the current state of the art. Therefore, the design engineer should continu-ously inform himself about changes in the standards and adapt his considerations to them. Relevant standards include EN ISO 13849 and EN 62061. This application must be regarded only as assistance for the considerations about safety measures.The design engineer of a machine/installation is obligated to assess the safety technology itself. The examples must not be used for assessment, because only a small excerpt of a complete safety function was considered in terms of safety engineering here. In order to be able to use the safety switch applications correctly on safety doors, it is indispensable to observe the standards EN ISO 13849-1, EN ISO 14119 and all relevant C-standards for the respective machine type. Under no circumstances does this doc-ument replace the engineer’s own risk assessment, and it cannot serve as the basis for a fault assessment.Particularly in case of fault exclusion, it must be noted that this can be performed only by the design engineer of a machine or installation and requires a reason. General fault exclusion is not possible. More information about fault exclusion can be found in EN ISO 13849-2.Changes to products or within assemblies from third-party suppliers used in this example can lead to the function no longer being ensured or the safety assessment having to be adapted. In any event, the information in the operating instructions on the part of EUCHNER, as well as on the part of third-party suppliers, must be used as the basis before this application is integrated into an overall safety function.

西门子PLC与三菱变频器Profibus-DP通信的说明
西门子PLC与三菱变频器Profibus-DP通信的说明三菱电机自动化（中国）有限公司巢晓阳一．三菱变频器部分FR-A7NP是FR-A700和FR-F700系列变频器进行Profibus-DP通信的通信选件。
FR-A7NP E-kit是FR-E700系列变频器进行Profibus-DP通信的通信选件。
FR-A7NP与FR-A7NP E-kit的主体都是一样的，只是FR-A7NP E-kit比FR-A7NP多了一些用于安装到FR-E700系列变频器上面去的附件。
1．端子排列2．站号设置使用 FR-A7NP 上的节点地址开关可在“0H～7DH(16进制)”之间设定节点地址。
变频器复位或下次开机时此设定生效。
3．接线注：如选用标准Profibus电缆，需将红色线（Pin3，B）接D+，绿色线（Pin8，A）接D-。
4．相关参数设置在本例中，将Pr.340设置为10，重新上电后即进入网络运行模式。
二．西门子PLC部分（STEP7软件设置）1．安装GSD文件（FR-A7NP的GSD文件是melc08fa.gsd）2．在右侧窗口中选中FR-A7NP并拖至DP主站总线上3．在右侧窗口中选中PPO type2并拖至下面的窗口中三．相关说明1．PPO type2的格式：2．控制变频器正、反转运行（通过STW）的说明：根据之前在STEP7软件中的设置，在本例中STW即为QW40，所以：①如果要正转，则：STF信号（b11）为ON，STR信号（b12）为OFF，PZD启用（b10）为ON，控制启用（b3）为ON。
由此得出STW为1000 1100 0111 1111，即8C7F。
②如果要反转，则：STF信号（b11）为OFF，STR信号（b12）为ON，PZD启用（b10）为ON，控制启用（b3）为ON。
由此得出STW为1001 0100 0111 1111，即947F。
③如果要停止，则：STF信号（b11）为OFF，STR信号（b12）为OFF，PZD启用（b10）为ON，控制启用（b3）为ON。

西门子PLC控制系统与第三方设备之间的通讯方式
西门子PLC控制系统与第三方设备之间的通讯方式作者：柏宁娟来源：《电子技术与软件工程》2016年第07期主要介绍了西门子PLC在风机控制系统中与第三方设备的通讯方式，重点讲述了西门子S7-400H冗余控制系统与高炉控制系统之间的通讯；与本特利3500监测系统的Modbus通讯；与独立的远程I/O站的Profibus总线通讯以及与远程控制系统S7-400和S7-300之间的通讯。
【关键词】西门子PLC 通讯方式 Profibus总线通讯 Modbus通讯工业通讯在自动化技术领域一直发挥着重要的作用。
工业以太网广泛应用于工厂的控制级通讯，以实现PLC与PLC之间，PLC与上位机之间的通讯。
高炉鼓风机的控制系统与用户高炉控制系统中采用最多的就是以太网通讯，走的是上位通讯。
与本特利3500监测系统的通讯是走下位Modbus通讯，与西门子电机的变频启动装置或者用户远程I/O站的通讯走的都是下位Profibus DP总线通讯。
下面就某项目中的通讯方式应用来阐述。
1 以太网通讯方式以西门子S7-400冗余系统为例，工程师站和操作员站通过工业以太网卡和交换机连接，交换机和CPU之间通过以太网连接，交换机的RJ45口或者光口都可以和用户高炉系统或者其他设备都通过以太网实现通讯。
这样就可以在风机控制室内读取用户高炉或者其他设备的监测数据。
西门子交换机的光口采用多模光纤传输距离5km，单模光纤传输距离为26km。
这种以太网通讯方式在现场得到了广泛应用，如图1所示。
2 通过Profibus DP总线通讯方式S7-400H作为DP主站，可通过集成在S7-400 CPU上的PROFIBUS DP接口，可以连接ET200分布式I/O设备、现场设备、S7-300、SIMATIC S7-400（通过CP443-5）这些都作为从站连接到PROFIBUS DP接口上，这是西门子S7-400H系统和远程的I/O站的通讯。
远程I/O站也是ET200M结构，两者之间通过OLM（光电转换器）实现了PROFIBUS DP 总线的电气信号与光纤信号的转换，常用于PROFIBUS DP多个站之间总线串联，而且两者相对距离较远采用光电转换器。

关键词：Profibus PLC 变频器通讯西门子连铸机1 前言随着现代生产工艺的快速发展，现场对传动设备的快速性、连续性、系统性的要求越来越高。
单台变频器的独立运行模式已经不能满足要求，多台成组系统运行成为最大特点。
所有变频器的操作已经发展为计算机集中远程自动控制模式。
这些特点都建立在计算机、PLC、传动装置间的数据通讯的基础上，以此来实现变频器运行状态的监控和控制命令的下达。
由于西门子PLC具有可靠性高，抗干扰能力强；编程方便，功能完善，易于使用；控制系统设计、安装、调试方便；维修方便，维修工作量小；适应性强，应用灵活等特点，所以3#连铸机控制系统以西门子PLC 控制装置为核心。
该系统由公用PLC、铸流PLC、振动PLC、液面自动控制PLC、切割PLC组成，各PLC系统均采用西门子公司的S7-300系列产品，各PLC的主要功能如下：①公用PLC：主要完成大包回转台及包盖的旋转、升降控制；中间罐车行走、升降、横移对中控制；液压系统控制；出坯辊道、推钢机、冷床的控制。
②铸流PLC：（一流～五流）主要完成上、下拉机和矫机的控制；引锭杆及铸坯位置的跟踪控制。
仪表部分包括结晶器冷却水流量和压力的监控、二次冷却水的流量调节、设备冷却水以及其他过程参数的设定、采集、监视及回路调节等。
③振动PLC：结晶器非正弦振动的控制。
④液面自动控制PLC：塞棒控制。
⑤切割PLC：主要完成对火焰切割机行走、切割枪的行走、定位控制。
所有PLC系统都有独立的IP地址，通过工业以太网相连。
拉矫机系统选用的是基于Profibus 的西门子6SE70变频器构成的现场总线控制系统。
每台变频器均带有进线电抗器、出线电抗器、制动单元和制动电阻。
公共流PLC通过Profibus总线连接四台变频器（大包回转台、1#中包车、2#中包车、推钢机）；每一铸流PLC系统通过Profibus总线连接四台变频器（拉机上辊、拉机下辊、矫机、引锭杆）。

朗风快学PLC（十三）S7-300的通讯Profibus如何使用
朗风快学PLC（十三）S7-300的通讯Profibus如何使用很多接触过西门子PLC的都知道Profibus以及Profinet，其实这都是西门子的通讯协议，今天我们认识一下Profibus。
Profibus-DP是工业自动化中最常用的网络之一。
Profibus代表“过程现场总线”DP代表“分布式设备”一作用是分布想象一下，我们想要的工厂区域有一堆传感器和执行器连接到PLC的I/O模块，这些模块位于距离控制器大约1500英尺（40米）的位置要做到这一点，我们需要连接每一个这些传感器通过单独的导线连接到PLC，因此要记住1500英尺的距离，我们最终会得到大量的并行线，这可以增加安装系统的成本。
当我们使用Profibus-DP网络时。
现在让我们看看接线将如何变化，上图我们的I/O模块位于就在CPU旁边。
要使用Profibus-DP，我们可以在传感器附近放置一个控制箱然后将I/O模块移入其中;然后我们可以将传感器连接到I/O模块。
然后只使用一根DP网线（两芯屏蔽）就可以将很多的信号接回到CPU上，是不是很方便！我们具体的讲一下PROFIBUS。
一、网络拓扑PROFIBUS的典型通讯电缆是屏蔽双绞线，如图1所示。
屏蔽双绞线自带金属屏蔽层，可以有效减少信号衰减和现场带来的各种噪声干扰，从而使得有用的电子信号更加“洁净”，传输距离也会相应变长。
图1 屏蔽双绞线DP头子是专用于PROFIBUS通讯电缆的接头，就好比以太网的水晶头一般，如图2所示。
图2 DP头子DP头子在使用时，有以下几个注意事项：1、DP头子有ON和OFF两种工作状态，它决定了终端电阻是否起作用。
在PROFIBUS网络的中间站，DP头子要处于“OFF”状态，而在两端，则要选在“ON”状态。
“ON”状态下，终端电阻起作用，为网络提供了较高的抗干扰能力，避免信号反射的发生。
2、DP头子可同时接一进一出两条通讯电缆，实现多个站点之间的网络拓扑。
如图3所示。

S7 PLC如何同西门子调速器用PROFIBUS-DP通讯
S7 PLC如何同西门子调速器用PROFIBUS-DP通讯一、目的PROFIBUS作为一种广泛应用的现场总线标准，在控制系统中占有极其重要的地位。
随着智能化调速器的不断发展，其同上位机之间的高速通讯也成为市场的迫切需求。
虽然我们可以采用USS协议将PLC同SIEMENS调速器连接起来，但是对于大、中型控制系统，它的数据吞吐能力以及协议可靠性已经不能满足要求。
因此采用PROFIBUS总线系统实现PLC同调速器的通讯连接，可以极大地提高我们控制系统的设计水平和产品档次。
二、硬件连接1、CBP的安装CBP为Master系列调速器的PROFIBUS接口板。
先将电子箱中的主电子板取出，将LBA总线装入，再将主电子板插回。
然后把CBP装在ADB适配板上，插入电子箱并固定。
2、PLC的安装PLC安装方式如下图：3、通讯线路的连接PROFIBUS的硬件接口为D型九针插头。
连接时可采用西门子提供的总线连接器，按下图接线，并在两端打开终端电阻开关。
三、参数设置1、设置调速器参数在硬件连接完毕后，需要对调速器的以下参数进行设置，以便CBP能够正常工作。
•设置PPO类型•设置报文监控时间•设置CBP的PROFIBUS站点地址•设置CBP的参数使能状态2、设置PLC参数对CPU的DP接口进行参数设置，使其能够参数化CBP。
•PPO•CBP站点地址3、连接诊断设置完成后，PLC及调速器送电，此时CBP上三个发光管同时闪亮，表示通讯正常。
四、程序编制1、有关DVA－S7DVA－S7是西门子公司为调速器同S7 PLC通讯所提供的S7软件包，它运行于PROFIBUS－DP之上，符合欧洲传动产品生产商有关变速传动在DP上应用的协定。
它内含参数发送及接收的功能块，以方便编程者调用。
采用DVA－S7编制程序，主要组成部分为：DP－SEND（参数发送功能块），DP－RESV（参数接收功能块），过程参数数据块，通讯参数数据块。
通讯功能块需要两个数据块，以便进行过程的参数化和提供通讯参数的存取空间。

Slots 4 to 11 are permissible (1, 2 and 3 cannot be used for CPs).Figure 4-1Example: Hardware Configuration S7-300 with SIMATIC NET CPs in the Central Rack The SIMATIC NET CPs can be installed both in the central rack and in anextension rack, linked to the central rack via an IM360/IM 361 (K-bus connection). 4Slot Rules and ConfigurationsA–25S7-CPs for PROFIBUS / Manual Part A – General Section Release 2/20034.1.2Number of SIMATIC NET CPsIn typical S7–300 configurations, the simultaneous operation of up to 4 CPs of the same type has been tested successfully. The actual number of SIMATIC NET CPs that can be operated at the same time is determined by the system (for example by the CPU resources).The connection resources available in the CPU can result in a further limitation.The load on the CPU resulting from communication jobs may also represent afurther restriction. The following factors should be noted:S Execution Time of the Blocks:For communication between the S7-300 CPU and SIMATIC NET CPs, blocks(FCs/FBs) are necessary. How often these blocks are called depends on thenumber of connections or the number of SIMATIC NET CPs. Depending on the amount of data transmitted, every block call extends the time required by theuser program.S Data conversion:It may also be necessary for the information to be converted beforetransmission or after reception.4.1.3MulticomputingThis functionality is not supported by the SIMATIC S7/C7-300.4.1.4CPU Connection Resources and Optimized UtilizationNote that when using older S7-300 CPUs (up to September 1999), a maximum of four S7 type connections for CP communication are supported. Of these fourconnections, one is reserved for a PG and another for an OP (HMI = HumanMachine Interface). The newer CPUs (from 10/99 onwards) support up to 12 S7connections, CPU 318-2DP supports 32 S7 connections.As a result, the older S7-300 CPUs have only two “free” S7 connections available.These two connections can be used for S7 communication, for PROFIBUS-FMS,or for longer data with Industrial Ethernet.If you use CPs that support multiplexing of OP connections and S7 communication with loadable communication blocks, only one connection resource is occupied when the multiplex channel is used.Slot Rules and ConfigurationsA–26S7-CPs for PROFIBUS / Manual Part A – General SectionRelease 2/20034.2SIMATIC S7-4004.2.1Permissible SlotsAn S7-400 CP can be inserted both in the central rack and in the extension rackwith a K bus interface. For the total number of CPs you can install, please refer tothe information on the relevant CP in the “Properties” chapter.Figure 4-2Example: Hardware Configuration S7-400 with SIMATIC NET CPs in the Central Rack In the SIMATIC S7/M7-400 there is no set slot assignment for the SIMATIC NETCPs. Slots 2 to 18 are permissible. Note, however, that depending on the powersupply module installed, slot 1 may also occupy slots 2–3.。
