S7-PLC SIM使用入门手册

一、引言PLC的用户程序设计好后，要用实际的PLC硬件来调试。

但以下情况则需要对程序进行仿真调试：①控制设备不在本地，设计者需对程序进行修改和调试；②程序设计好后，PLC硬件尚未购回；③在实际系统中进行某些调试有一定风险。

为了解决这些问题，一些PLC生产厂家提供了可代替PLC硬件调试的仿真软件，本文主要介绍西门子公司的S7一PLCSIM仿真软件。

二、S7-PLCSIM概述1、S7-PLCSIM的主要功能（1）仿真软件还可模拟对位存储器、外围输入变量区和外围输出变量区的操作，以及对存储在数据块中的数据（如DBl.DBX0.0或DBl.DBW0等）的读写。

（2）可实现定时器和计数器的监视和修改，通过程序使定时器自动运行或手动复位。

（3）可对S7-300和S7-400 PLC的用户程序进行离线仿真与调试，可访问模拟PLC的I/O存储器、累加器和寄存器。

通过在仿真运行窗口中改变输入变量的ON/OFF状态来控制程序的运行，并观察有关输出变量的状态来监视程序运行的结果。

（4）可在仿真PLC中使用中断组织块测试程序的特性，并记录一系列操作事件及回放记录，从而自动测试程序。

2、S7-PLCSIM的主要组成部分（1）仿真PLCS7-PLCSIM用仿真PLC来模拟实际PLC的运行，用户可通过视图对象来调试程序。

它提供的多种视图对象可实现对仿真PLC内的各种变量、计数器和定时器的监视与修改。

（2）视图对象①CPU视图对象开始新仿真时，将自动出现CPU视图对象，用户可用单选框来选择运行、停止和暂停工作方式；MRES按钮用来复位存储器、删除块和删除仿真PLC中的硬件设置。

LED指示灯“SF'’表示软硬件错误；“RUN”与“STOP”表示运行与停止状态；“DP”（分布式外设或远程I/O）指示PLC与分布式外设或远程I/O的通信状态；“DC”（直流电源）指示电源的通断情况。

②插入视图对象输入变量（I）、输出变量（Q）和位存储器（M）视图对象分别用于访问和监视相应的数据区，可以以位、二进制、十进制、十六进制、字符及字符串的形式访问。

Siemens’ products and solutions constitute one element of such a concept.Customers are responsible for preventing unauthorized access to their plants, systems,machines and networks. Such systems, machines and components should only be connectedto an enterprise network or the internet if and to the extent such a connection is necessaryand only when appropriate security measures (e.g. firewalls and/or network segmentation) arein place.For additional information on industrial security measures that may be implemented, pleasevisit:https:///industrialsecuritySiemens’ products and solutions undergo continuous development to make them more secure.Siemens strongly recommends that product updates are applied as soon as they are availableand that the latest product versions are used. Use of product versions that are no longersupported, and failure to apply the latest updates may increase customer’s exposure to cyberthreats.To stay informed about product updates, subscribe to the Siemens Industrial Security RSSFeed underhttps:///industrialsecurity.Configuration Symantec Endpoint Protection V14Commissioning Manual, 03/2018, A5E44395521-AA5Security informationConfiguration Symantec Endpoint Protection V14 6Commissioning Manual, 03/2018, A5E44395521-AAPreface2 This documentation describes the settings of Symantec Endpoint Protection (SEP) that needto be changed for use in an industrial plant.The configuration represents an extract of the settings from SEP which were used in thecompatibility test with PCS 7 and WinCC.Important information about this whitepaperNoteThe recommended settings for these virus scanners have been chosen to ensure that thereliable real-time operation of PCS 7 is not adversely affected by the virus scanner software.These recommendations describe the currently known, best-possible compromise betweenthe objective of maximizing the detection and neutralization of virus software and malware andguaranteeing a highly deterministic time behavior of the PCS 7 process control system in alloperating phases.If you choose different settings for the virus scanner, this could have negative effects on thereal-time behavior.Purpose of the documentationThis documentation describes the recommended settings for virus scanner software incombination with PCS 7 and WinCC following the virus scanner installation.Required knowledgeThis documentation is aimed at persons involved in the engineering, commissioning, andoperation of automated systems based on SIMATIC PCS 7 or WinCC. Knowledge ofadministration and IT techniques for Microsoft Windows operating systems is assumed.In addition, readers should be familiar with the PCS 7 & WinCC security concept.Additional information is available on the Internet at the following address:Security concept (https:///WW/view/en/60119725) Configuration Symantec Endpoint Protection V14Commissioning Manual, 03/2018, A5E44395521-AA7PrefaceScope of the documentationThis documentation applies to process control systems that are realized with the correspondingPCS 7 or WinCC product version.NoteNote that certain virus scanners are only approved for certain product versions.

The following configurations refer to the centrally managed SEPvariant, which is configured using the SEP Manager. The use of a local, non-managedinstallation is allowed, but is not described. In addition, only an English installation is referredto. All the configurations described are deviations from the default configurations, i.e. anysettings not described are not changed.3.2NoticeThe following setting is essential for stable operation of PCS 7.Under "Clients->My Company->Policies->External Communication Settings:UncheckClient Submission Send anonymous data to Sy‐mantecUncheckClient Queries Allow Insight lookups for threaddetectionWhen this option is active, the virus scanner attempts to contact Symantec Server directly onthe Internet during each file scan. There is a significant delay if the virus scanner cannot reachthe server. This makes the stable operation of PCS 7 impossible.All other check boxes under Submission Settings should also be cleared so that no internalinformation, even if it is anonymous, is sent to Symantec. The other options do not have anegative effect on PCS 7, however.Client RestartClients should never be restarted automatically. You should disable an automatic restart intwo places.Under "Clients->My Company->Policies->General:Restart Settings Restart method No restartGenerate a new policy under Install Packages->Client Install Settings:Restart Settings Restart method No restartConfiguration Symantec Endpoint Protection V14Commissioning Manual, 03/2018, A5E44395521-AA93.3Overview of SEP modules and functions SEP has the following configurable modules that can be configured with policies (available in the SEP under "Policies"):●Virus and Spyware Protection ●Firewall ●Intrusion Prevention ●Application and Device Control ●Host Integrity ●LiveUpdate ●Exceptions Additional settings (available in the SEP Manager under Clients > Policies > Location- independent Policies and Settings):●Custom Intrusion Prevention ●System Lockdown ●Network Application Monitoring The following modules and settings are recommended and are tested for compatibility for use in a PCS 7 and WinCC environment:●Virus and Spyware Protection ●Intrusion Prevention ●Device Control ●Host Integrity (provisional)●LiveUpdate ●Network Application Monitoring The following modules and settings are not recommended and are not checked in the compatibility test:●Firewall – Only the Windows Firewall is released for use with PCS 7 and WinCC as this is configured automatically depending on the product installed.●Application Control – This involves computer-specific settings that cannot be checked.●Exceptions – This involves system-specific settings that cannot be checked.●Custom Intrusion Prevention – This involves plant-specific settings that cannot be checked.●System Lockdown – This involves computer-specific settings that cannot be checked.For this reason, no policies should be assigned for these modules and the settings should not be switched "On".

西门子PLC入门基础教程1、PLC基本概念可编程控制器（Programmable Controller）是计算机家族中的一员，是为工业控制而设计制造的。

早期的可编程控制器称作可编程逻辑控制器（Programmable Logic Controller），简称 PLC，它主要用来代替继电器实现逻辑控制。

随着技术的发展，这种装置的功能已经大大超过了逻辑控制的范围，因此，今天这种装置称作可编程控制器，简称PC。

但是为了避免与个人计算机（Personal Computer）的简称混淆，所以将可编程控制器简称PLC。

2、PLC的基本结构PLC实质是一种专用于工业控制的计算机，其硬件结构基本上与微型计算机相同。

A、中央处理器（CPU）中央处理器（CPU）是PLC的控制中枢。

他按照PLC系统成程序赋予的功能接收并存储从编程器键入的用户程序和数据；检查电源、存储器、I/O以及警戒定时器的状态，并能诊断用户程序中的语法错误。

当PLC投入运行时，首先他以扫描的方式接受现场各输入装置的状态和数据，并分别存入I/O映象区，然后从用户程序存储器中逐条读取用户程序，经过命令解释后，按指令的规定执行逻辑或数字运算的结果送入I/O映象区或数字寄存器内。

等所有的用户程序执行完毕之后，最后将I/O映象区的各输出状态或输出寄存器内的数据传送到相应的输出装置，如此循环运行，直到停止运行。

为了进一步提高PLC的可靠性，近年来对大型PLC还采用双CPU构成冗余系统，或采用三CPU的表决式系统。

这样即使某个CPU出现故障，整个系统仍能正常运行。

B、存储器存储系统程序的存储器称为系统存储器。

存储应用软件的存储器称为用户存储器。

{(一) PLC常用的存储器类型1. RAM (Random Assess Memory)这是一种读/写存储器(随机存储器)，其存取速度最快，由锂电池支持。

2. EPROM (Erasable Programmable Read Only Memory)这是一种可擦除的只读存储器。
