Data from these assets can be collected, aggregated and processed, to provide visibility of system conditions. The Multilin TM D20MX Substation Controller is a specialized computing platform designed to execute communications and energy management applications for the monitoring and control of electrical substations. The D20MX is capable of amalgamating data from multiple slave devices and D20 I/O modules connected via communication channels into a single database using various protocols. The D20MX can execute local logic, compile data, process it through one of multiple applications and report the results upstream to master stations through different server protocols. The D20MX represents the next innovation in GE’s cyber secure RTU technology for NERC-CIP environments. The D20MX is built upon the field-proven Multilin D20 technologies and continues the tradition of reliable automation and control through high quality and long term product availability.Key Benefits• Reduces legacy D20 RTU upgrade expenditures by over 50% through backwards compatibility with existing D20 installed accessories, such as chassis, modems and D20 I/O peripheral modules • Minimizes operation and maintenance costs of existing D20-based SCADA infrastructure by leveraging existing designs, processes and infrastructure • Introduces a new and modern network security feature suite that enables effective compliance with NERC ® CIP requirements through the application of native cyber security features built into the D20MX Substation ControllerApplicationsData ConcentratorAutomatically consolidates collected information from intelligent electrical devices (IEDs), such as relays and meters, and communicates to SCADA, EMS, DMS and Data Historian systemsProtocol ConverterTranslates different data message formats between devices to support interoperabilityLocal Automation PlatformImplements popular distribution automation applications such as capacitor bank control, outageprevention programs, feeder resource optimization and control interlocking, inhibition and subgroupingMultilin ™D20MXAdvanced ControllerThe Multilin D20MX Substation Controller collects, filters, and sorts data from a wide range of intelligent devices (RTUs, relays, meters) in the substation. The D20MX preserves original data time stamps for accurate sequence of event (SOE) logs, allowing data from large diverse geographic regions and time zones to be analyzed in extreme detail. Data can be presented simultaneously to multiple SCADA hosts. The D20MX comes with a built-in suite of protocols and security applications to facilitate integration with various substation devices and SCADA hosts.D20MX is the sixth generation of D20 CPUs designed to provide a smooth migration path for D20 users to extend the life of aging D20 systems. It introduces a new and modern network security feature suite that enables effective compliance with NERC-CIP requirements, using open and trusted standards and protocols that allow integration with modern cyber security systems and tools.D20MX Controller Main Connectivity ApplicationsAdvanced Substation Controller ConnectivitySample Enterprise Protocols:• DNP3 serial and Ethernet [TCP/UDP/IP]• Tejas V • HR6000/XA-21• Modbus serial (RTU or ASCII)• IEC 101/104• LG-8979 • PG&ED20MX Media Connectivity:• 7 serial ports (RS232)• Built-in dual Ethernet ports• (10/100/1000 Base TX or 100 Base FX) Dual D.20 communication portsSample Device Protocols:• DNP3 serial and Ethernet[TCP/UDP/IP]• Modbus serial (RTU or ASCII)• IEC 101/104• SEL• IRIG-B supportV1.4B021-0DNP3 DPA •B021-0DNP3 DPA •A068Modbus DPA •A033-5Tejas V DPA •A185-0LG 8979 DPA •A009PG&E DPA•A101-0IEC 60870-5-101/104 DPA •A003Harris 6000/XA-21 DPA •A135-0 Modbus TCP/IP DPA •A023 CDC TYPE I DPA•V1.4B023-0DNP3 DCA •A059Modbus DCA •A078-0SEL DCA•B060-0IEC 60870-5-101/104 DCA •A131-0Modbus TCP/IP DCA•A018Quantum Meter Scanner DCA •A194-0COOPER 2179 DCA •B080-0IEC 60870-5-103 DCA•GE P/N DATA TRANSLATION APPLICATIONS [DTA]V1.1V1.2V1.3V1.4A030Accummulator Freeze DTA •A035Analog Reference DTA •A118Failover DTA•A184-0General Alarm DTA •B009Mailbox DTA•A123-0NGC General DTA•A113Programmable Synchro Check Relay DTA •A036Prologic Executor DTA •A027SOE Logger DTA•A088-0Substation Maintenance DTA •A027-1Communications Watchdog •A083-0Calculator DTA •A195Redundant I/O DTA •B099-0SNTP Client DTA•B082-0LogicLinx Executor DTA•A041-1Proportional Integrator Derivative Control DTA •B148Time Zone and DST Setting DTA •A017DNP V1.00 DATA LINK DTA•A161-0 Secondary Master Trip/Close DTA •A121-0Automatic Frequency Selection DTA •A048Status Combination DTA •A104-0N Alarm Grouping DTA•A193-0Top of the Hour Analog Averaging DTA •A186-0Western Power Distribution (WPD) DTA •B119-1NLAN Redundancy Manager DTA•IEDs/MetersProtection RelaysBay ControllersD20MX Classic and Advanced Automation ApplicationsD20MX CLASSIC APPLICATIONSA009PG&E DPAA033-5Tejas V DPAA036Prologic Executor DTAA113Programmable Synchrocheck Relay DCA A185-08979 DPAA194-0COOPER 2179 DCAA199-0HR6000/XA-21 DPA D20MX CLASSIC APPLICATIONSA041-1Proportional Integrator Derivative Control DTA A018Quantum Meter Scanner DCAA023CDC Type I DPAA017DNP V1.00 Data Link DTAD20MX ADVANCED AUTOMATION APPLICATIONSB082-0Logiclinx Executor DTAUpgrade of Legacy D20 RTUsThe Multilin D20MX is more than an RTU. It’s a commitment to the ongoinglong term availability of GE’s automation products. Utilities have largeinvestments in hardwired automation systems.Like everything else, this industrial equipment has a lifecycle that movesfrom infancy to normal operation, and eventually to the wear out stages. Asa piece of equipment ages it fails more frequently, takes longer to repair, andeventually reaches the end of its life. Re-design and forklift replacementsrequire utilities to re-engineer substation designs, replace field wiring, andretrain staff to manage and maintain the system, which is a costly endeavor.The Multilin D20MX provides a cost-effective alternative to upgrades of legacyD20 RTUs. This means that the investments made in GE’s automation systemskeep paying dividends beyond their originally projected end of life. Simplyreplace the failed or end of life Multilin D20 processor module with a MultilinD20MX and migrate the device configuration to extend the life of the existingD20 Controller. Add cyber security features for integration into NERC-CIPenvironments. As technology changes with market demands, GE continues toinvest in a partnership with their customers through advanced modular designprincipals.Integration of D20 Substation Controllers into NERC-CIP EnvironmentsThe Multilin D20MX supports a comprehensive set of security functions to allow a seamless integration with existing IT department policies. Built-in cyber security features, such as Remote Authentication Dial-In User Service (RADIUS), Role Based Access Control (RBAC), and user activity logging, provide a complete security toolkit required to enable effective compliance with NERC-CIP requirements, using open and trusted standards and protocols, that allow integration with modern cyber security systems and tools. RADIUSRADIUS is a client/server networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for computers to connect and use a network service. With RADIUS each user in your system has their own unique identification login, allowing you to control who gets access to what devices from where. RADIUS provides centralized AAA management for computers to connect to the D20MX.If one of the current users of your D20MX leaves your company, you can lock down access to all the devices in your network from a central location. That user instantly loses access to every D20MX, while other users remain able to do their jobs without any adverse effects and costly password change programs.AAA Network AccessRadius servers use the AAA concept to manage network access by following a few steps referred to as AAA transactions.AuthenticationThe user sends a request to gain access to a particular resource using access credentials, typically, in the form of user name and password.The RADIUS server verifies the user’s credentials and accepts or rejects access. The D20MX supports primary and secondary RADIUS servers. If for any reason the D20MX is not able to authenticate the user against the RADIUS servers, the D20MX verifies the user’s credentials against a local password file.AuthorizationIn a typical centralized user authentication system, access terms are defined on a per user basis. For example, the following authorization attributes may be associated for a specific user:• Specific D20MX IP address to be accessed by the user• Role ID assigned to the user, where role ID defines which commands and displays the user is able to access on the D20MX• Allowed time-of-day during which users can access the network AccountingWhen access is granted to the user, their activity can be registered for security, system integrity monitoring and statistical purposes. For example, the following user’s activity can be recorded:• User information• Login time stamp• Logout time stampThe D20MX provides accounting information by logging the user’s activity to a remote syslog server.RBACRBAC is achieved using RADIUS or the D20MX’s internal database, ensuring only authenticated and authorized users gain access to the system.When you configure the D20MX to use RADIUS, each D20MX user is identified by a role ID, which is an integer number provided by the RADIUS server. The D20MX makes your life easier by including a pre-configured default RBAC model.When using RADIUS, revoking user privileges system-wide is as simple as updating the centralized user database, saving you time and money.Advanced AutomationSince releasing the first generation D20 back in 1988, GE’s automation experts have learned a lot. Through challenging projects and installations across the globe, the D20 has evolved into a leader in substation automation. The culmination of that experience is the sixth generation, the Multilin D20MX. The following are a sample of the advanced automation features available today.Substation MaintenanceIf there is one thing operators hate, it’s false alarms. The D20MX can suppress reporting of input points while they are unavailable during maintenance. This allows users to disable groups of analog and digital input points by ignoring their actual data and quality changes within selected applications. While points are suppressed, a predefined suppression value and the point suppression quality flag are provided instead. This is useful during maintenance operations to prevent spurious OFFLINE alarms and inaccurate readings while devices are powered off or disconnected during the execution of maintenance activities.Centralized Authentication and Authorization1. Login attemptAccumulator FreezeMonitoring constantly incrementing and changing values, such as time of use, and energy consumption across a system, makes accurate comparisons of data a time-consuming effort. GE’s accumulator freeze application simplifies this process automatically by capturing the instantaneous value of accumulator records across the system at the same point in time, giving engineers and operators a clear understanding of the state of their system.A popular example of the use of accumulators is energy metering, where pulse streams from meter pulse generators is proportional to energy flow. This feature allows users to define groups of accumulator points whose values are frozen periodically or on demand.Alarm ManagementThe D20MX manages alarms based on real substation experience. This application allows user-defined logical grouping of individual digital inputs to generate general alarms based on the status of the signals monitored within each group. Alarm groups are user-definable, with up to 32766 groups allowed. Status inputs may belong to as many groups as required.The great flexibility of this application ensures that each group has its own meaningful description and configurable latching or non-latching operation modes. Latching alarms require operator acknowledgement for optimized management of critical conditions in the system.System RedundancyAlthough the D20 family of RTUs is legendary for quality, GE has prepared for those rare cases when a processor is unable to function. Through time tested and utility accepted redundancy mechanisms, the D20MX is designed for high availability requirements. In redundant processor mode, one device stands waiting, ready to take over, should the other unit stop functioning.Dual D20MX units can be deployed, creating a redundant system where accumulators are automatically synchronized between the two systems and configurations are synchronized on demand. Serial communication links are automatically switched between the units based on system health.The D20MX has redundant Ethernet, enabling automatic switchover between two sets of Ethernet switches, ensuring there is no single point of failure in the system.Control LockoutThe control lockout feature ensures that only a single master station can access a group of controls at one time, and can lock out groups of controls to allow for safer local maintenance. Users can create custom control groups. Any digital output can be included in any control group.Analog Inputs MonitoringGE’s analog reference provides enhanced and simplified monitoring of analog input monitoring equipment. Operators define a reference value used to compare against monitored signals. The application reports failures in analog input hardware, allowing effective maintenance of the monitoring devices, reduced downtime and increased reliability of the system.SGConfig Setup SoftwareThe Multilin SGConfig software integrates support for the complete portfolio of GE’s Substation Controllers, including the D20MX series. The SGConfig software introduces an updated graphical user interface while maintaining configuration processes and workflows available in the ConfigPro setup software.Convenient access to product documentation and screencasts is provided directly from the SGConfig software. (Screencasts are short instruction videos on popular setup processes.)Typical Architecture for Redundant D20 Substation Control SystemRS232 CommunicationsD20MXSubstation IEDEthernet Switch BEthernet Switch ALAN A LAN BSubstation IEDD20MXSubstation IEDHardware OverviewFully Equipped Out-of-the BoxPrevious generations of D20 RTUs required add-on system components and software to support Ethernet communications and optional memory expansion.

S7-1200的指令
3.2 定时器与计数器指令 3.2.1 定时器指令
1．脉冲定时器 将指令列表中的“生成脉冲”指令TP拖放到梯形图中，在出现的“调用选 项”对话框中，将默认的背景数据块的名称改为T1，可以用它来做定时器的 标示符。单击“确定”按钮，自动生成背景数据块。 定时器的输入IN为启动 输入端，PT为预设时间值，ET为定时开始后经过的当前时间值，它们的数据 类型为32位的Time，单位为m均可以使用I（仅用于输入参数）、Q、M、D、L存储区，PT可以 使用常量。定时器指令可以放在程序段的中间或结束处。
3．关断延时定时器指令 关断延时定时器（TOF）用于将Q输出的复位操作延时PT指定的一段时间。 IN输入电路接通时，输出Q为1状态，当前时间被清零。在IN的下降沿开始定 时，ET从0逐渐增大。ET等于预设值时，输出Q变为0状态，当前时间保持不 变，直到IN输入电路接通（见波形A）。关断延时定时器可以用于设备停机 后的延时。 如果ET未达到PT预设的值，IN输入信号就变为1状态，ET被清0，输出Q保 持1状态不变（见波形B）。复位线圈RT通电时，如果IN输入信号为0状态， 则定时器被复位，当前时间被清零，输出Q变为0状态（见波形C）。如果复 位时IN输入信号为1状态，则复位信号不起作用（见波形D）。
【例3-2】 用接通延时定时器设计周期和占空比可调的振荡电路。 图3-22中的串联电路接通后，定时器T5的IN输入信号为1状态，开始定时。 2s后定时时间到，它的Q输出使定时器T6开始定时，同时Q0.7的线圈通电。 3s后T6的定时时间到，它的输出“T6”.Q的常闭触点断开，使T5的IN输入电 路断开，其Q输出变为0状态，使Q0.7和定时器T6的Q输出也变为0状态。下一 个扫描周期因为“T6”.Q的常闭触点接通，T5又从预设值开始定时。Q0.7的 线圈将这样周期性地通电和断电，直到串联电路断开。Q0.7线圈通电和断电 的时间分别等于T6和T5的预设值。

S7-1200CPU固件版本更新的三种方式
S7-1200CPU固件版本更新的三种方式S7-1200 CPU的固件可以通过以下3种方式进行升级：使用存储卡更新CPU固件。
使用TIA 软件更新CPU固件。
通过Web访问方式更新CPU固件。
1使用存储卡更新CPU固件注意事项：不同订货号的S7-1200CPU的固件文件不相同。
用户在下载和更新固件之前请核对产品订货号。
12M以下存储卡不能用于CPU固件升级。
固件升级前CPU内部存储的项目文件（程序块、硬件组态等）不受影响，不会被清除。
如果存储卡中的固件文件订货号与实际CPU的订货号不一致，即使执行了下列步骤，CPU的原固件版本也不会改变。
详细步骤：第一步：使用电脑通过读卡器清除存储卡中内容。
注意：不要格式化存储卡！第二步：从西门子官方网站下载最新版本的固件文件。
下载并解压缩，用户可以得到一个“S7_JOB.SYS”文件和“FWUPDATE.S7S”文件夹。
第三步：将“S7_JOB.SYS”文件和“FWUPDATE.S7S”文件夹拷贝到存储卡中。
第四步：将存储卡插到CPU1200卡槽中。
此时CPU会停止，“MAINT”指示灯闪烁。
第五步：将CPU断电上电。
CPU的“RUN/STOP” 指示灯黄绿交替闪烁说明固件正在被更新中。
“RUN/STOP” 指示灯亮(黄)，“MAINT”指示灯闪烁说明固件更新已经结束。
第六步：拔出存储卡第七步：再次将CPU断电上电用户可以在TIA PORTAL 软件--->在线和诊断--->诊断--->常规中在线查看CPU目前的固件版本。
注意：S7-1200 CPU 固件版本在 V2.2 以下(包括V2.2)，可以降级（最低V1.0)或升级（最高V2.2)。
S7-1200 CPU 固件版本在 V3.0 不可以降级至V2.2(或更低版本)，同样V2.2的固件版本不能升级至V3.0S7-1200 CPU 仅支持由西门子制造商预先格式化过的存储卡，即下列订货号产品：订货号容量SIMATIC MC 4 MB 6ES7 954-8LC03-0AA0SIMATIC MC 12 MB 6ES7 954-8LE03-0AA0SIMATIC MC 24 MB 6ES7 954-8LF03-0AA0SIMATIC MC 256 MB 6ES7 954-8LL03-0AA0SIMATIC MC 2G 6ES7 954-8LP02-0AA0SIMATIC MC 32G 6ES7 954-8LT03-0AA02使用TIA软件更新CPU固件1. 打开所连接S7-1200 CPU 的'在线和诊断'(Online and Diagnostics) 视图，并切换到“在线”模式。

西门子S7-1200启动模式及设置
西门子S7-1200启动模式及设置启动模式S7-1200 CPU 通电后，它在开始执行循环用户程序之前首先执行启动程序。
CPU 支持以下组态选项：● 不重新启动（保持为 STOP 模式）● 暖启动 - RUN 模式● 暖启动 - 断电前的模式启动模式设置S7-1200 启动模式可以在“CPU 属性-常规-启动” 进行设置。
如下图 1 所示：图 1. CPU启动选项设置①“上电后启动”：定义了CPU 上电后的启动特性，共有以下三个选项，用户可根据项目的特点及安全性来选择，默认选项为“暖启动-断电前的操作模式”：•“不重新启动（保持为STOP 模式）”：CPU 上电后直接进入STOP 模式；•“暖启动-RUN模式”：CPU 上电后直接进入RUN模式；•“暖启动-断电前的操作模式”：选择该项后，CPU上电后将按照断电前该CPU 的RUN模式启动，即断电前CPU处于运行模式，则上电后 CPU 依然进入RUN模式；如果断电前CPU 处于STOP状态，则上电后CPU进入STOP模式。
如果在发生掉电或故障时，CPU 处于STOP 模式，则CPU 将在上电时进入STOP 模式并保持STOP 模式，直至收到进入RUN 模式的命令；如果在发生掉电或故障时，CPU 处于RUN 模式，则在未检测到可禁止CPU 进入RUN 模式的条件下，CPU 将在下次上电时进入 RUN 模式。
②“比较预设与实际组态”：定义了S7-1200 PLC站的实际组态与当前组态不匹配时的 CPU 启动特性：•“仅在兼容时，才启动CPU”：所组态的模块与实际模块匹配（兼容）时，才启动CPU。
•“即便不匹配，也启动CPU”：所组态的模块与实际模块不匹配（不兼容）时，也启动CPU。
注意：如果选择了'即便不匹配，也启动CPU'，此时的用户程序无法正常运行，必须采取相应措施！所以要慎重选择该项。
③ “组态时间”：在 CPU 启动过程中，为集中式 I/O 和分布式 I/O分配参数的时间，包括为 CM 和 CP 提供电压和通信参数的时间。
S7-1200仿真器使用入门
S7-1200 PLCSIMS7-1200 PLC 仿真功能有如下硬件和软件要求：硬件要求：1、固件版本为 4.0 或更高版本的 S7-1200 PLC2、固件版本为 4.12 或更高版本的 S7-1200F PLC软件要求：S7-PLCSIM V13 SP1 及以上S7-1200 PLCSIM 支持范围一、工艺模块和工艺对象支持工艺模块支持S7-PLCSIM 目前不支持以下工艺模块：①计数②PID 控制③运动控制工艺对象支持S7-PLCSIM 目前不支持以下工艺对象：•运动控制•PID二、指令支持S7-PLCSIM 几乎支持仿真的 S7-1200 和 S7-1200F 的所有指令（系统函数和系统函数块），支持方式与物理 PLC 相同。
S7-PLCSIM 将不支持的块视为非运行状态。
某些指令受部分支持。
对于这些 SFC 和 SFB，S7-PLCSIM 将验证输入参数并返回有效输出，但不一定是带有实际 I/O 的真实 PLC 将返回的信息。
当前不支持的指令S7-PLCSIM 不支持或不完全支持仿真的 S7-1200 和 S7-1200F 的以下指令：三、通信指令支持S7-PLCSIM 支持 S7-1200 和 S7-1200F PLC 的如下通信指令：•PUT 和 GET•TSEND 和 TRCV注意：仿真PLC与“真实” PLC仍有区别，如下所述：1. T-block 指令和数据分段S7-PLCSIM 执行 T-block 指令时数据分段为 1024 字节。
实际 CPU 的数据分段为 8192 字节。
如果在单个 TSEND 指令中发送的数据超过 1024 字节，并且在 ad-hoc 模式下通过 TRCV 指令接收数据，则 TRCV 指令生成的新数据只有 1024 字节。
此时，必须多次执行 TRCV 指令才能接收额外的字节。
2. T-block 指令和数据缓冲S7-PLCSIM 执行 T-block 指令时无需在接收 CPU 中缓冲数据。
S7-1200的指令
【例3-2】 用接通延时定时器设计周期和占空比可调的振荡电路。 图3-22中的串联电路接通后，定时器T5的IN输入信号为1状态，开始定时。 2s后定时时间到，它的Q输出使定时器T6开始定时，同时Q0.7的线圈通电。 3s后T6的定时时间到，它的输出“T6”.Q的常闭触点断开，使T5的IN输入电 路断开，其Q输出变为0状态，使Q0.7和定时器T6的Q输出也变为0状态。下一 个扫描周期因为“T6”.Q的常闭触点接通，T5又从预设值开始定时。Q0.7的 线圈将这样周期性地通电和断电，直到串联电路断开。Q0.7线圈通电和断电 的时间分别等于T6和T5的预设值。
6．置位/复位触发器与复位/置位触发器 SR方框是置位/复位（复位优先）触发器，在置位（S）和复位（R1）信号 同时为1时，方框上的输出位M7.2被复位为0。可选的输出Q反映了M7.2的状态。 RS方框是复位/置位（置位优先）触发器，在置位（S1）和复位（R）信号 同时为1时，方框上的M7.6为置位为1。可选的输出Q反映了M7.6的状态。
5．置位位域指令与复位位域指令 “置位位域”指令SET_BF将指定的地址开始的连续的若干个位地址置位， “复位位域”指令RESET_BF将指定的地址开始的连续的若干个位地址复位。
7．扫描操作数信号边沿的指令 中间有P的触点的名称为“扫描操作数的信号上升沿”，在I0.6的上升沿， 该触点接通一个扫描周期。M4.3为边沿存储位，用来存储上一次扫描循环时 I0.6的状态。通过比较I0.6前后两次循环的状态，来检测信号的边沿。边沿存 储位的地址只能在程序中使用一次。不能用代码块的临时局部数据或I/O变量 来作边沿存储位。 中间有N的触点的名称为“扫描操作数的信号下降沿”，在M4.4的下降沿， RESET_BF的线圈“通电”一个扫描周期。该触点下面的M4.5为边沿存储位。

SIMATICS7-12002016 年 9 月版 S7-1200 系统手册更新产品信息S7-1200 文档更新概述尽管我们力求确保产品文档条理清楚与准确无误，但S7-1200可编程控制器系统手册的一些页面仍被发现包含有不完整的、不正确的或误导性的信息。
本文档包含下列更新信息●当控制器与智能设备之间的网络连接断开时，输入传送区存在不同的处理方式。
(页 2) ●指令完成前，必须将 Modbus RTU, Modbus_Comm_Load 的 EN 参数保持为真 (页 2) ●运动控制轴组态编码器模块 (页 2)●Web 服务器恢复操作可能出现的错误 (页 2)●OB 0 缓冲区溢出诊断事件的原因 (页 2)●“模拟值的处理”更正 (页 3)●信号模块 (SM) 上的状态 LED 表更正 (页 3)●SM 1231 AI 8 x TC 位的连接器引脚位置表更正 (页 3)●RALRM（接收中断）指令的 TINFO 和 AINFO 参数说明 (页 3)●CPU 电源表的更正 (页 4)●时间源组态 (页 4)●运行条件表勘误 (页 5)●勘误表：模拟量输入的阶跃响应、采样时间和更新时间 (页 5)●配方数据：编辑 PLC 数据类型元素的名称字段 (页 6)●说明更新：章节 11.5“S7 通信”，设备更换 GET/PUT 操作使能 (页 6)●说明更新：章节 9.8.4“为 PWM 或 PTO 组态脉冲通道”PWM 最短周期时间 (页 6)●STARTUP 和 RUN 模式下的 CPU 行为 (页 7)© Siemens AG 2017. 保留所有权利当控制器与智能设备之间的网络连接断开时，输入传送区存在不同的处理方式。
当网络连接断开时，CPU 将零写入控制器上的输入传送区。
在智能设备上，输入传送区保持其最后的值。
您可以组态系统以避免在常规智能设备（非共享智能设备）上出现这种情形。
为此，针对进入事件，清除“机架或站故障OB”中智能设备的输入传送区。
请按以下步骤操作：1.在您的项目中添加一个“机架或站故障 OB”(Rack or Station Failure OB)。
（该 OB 编号默认为 OB 86）。
2.向 OB 添加逻辑，从而当 LADDR 的启动变量指示智能设备硬件 ID 的值并且 Event_Class的启动变量指示一个“进入”事件时，将智能设备的输入值写为零：–您可以在“系统常量”(System constants) 选项卡的默认变量表中找到智能设备硬件 ID。
硬件 ID为“HW_Device”类型，变量名指示其为智能设备（例如，“Local~PROFINET_interface_1~IODevice”）。
–Event_Class 中的“16#39”值表示一个“进入”事件。
如果“Event_Class”输入变量包含“16#39”值，这表示“机架或站故障OB”当前处于激活状态（与清除状态相反）。
指令完成前，必须将 Modbus RTU, Modbus_Comm_Load 的 EN参数保持为真Modbus RTU、Modbus_Comm_Load 指令使用读取数据记录和写入数据记录功能初始化 PTP 模块。
但 RDREC/WRREC指令异步运行，这意味着需要几次扫描才能完成指令运行。
因此，您必须保持 Modbus_Comm_Load 的 EN 参数为真，直到RDREC/WRREC 指令运行结束。
运动控制轴组态编码器模块在章节 10.3.4.7“使用 TM 脉冲模块进行轴控制”中组态具有位置反馈的运动轴的步骤中，“步骤4”将引导您选择编码器。
正确的编码器列表由以下各项组成：●TM 计数模块●TM PosInput 模块●高速计数器 (HSC)Web 服务器恢复操作可能出现的错误从 S7-1200 V4.2.0 Web服务器在线备份页面执行恢复操作时，有时候无法完成恢复操作。
在这种情况下，在线备份页面会显示以下消息之一：●加载在线备份时出错。
错误 6：将备份文件写入 CPU 时出错。
●加载在线备份时出错。
错误 0：内部错误。
如果恢复失败，请重新尝试。
如果仍然失败，请使用 Internet Explorer 重新尝试。
恢复操作对于 S7-1200 V4.2.1 Web 服务器不会生成此错误。
OB 0 缓冲区溢出诊断事件的原因如果您已经在 CPU 的设备组态中组态了数字量输入的上升沿或下降沿检测，但未组态在该信号沿进行触发的OB，则当输入快速重复地触发一个上升/下降沿时，诊断缓冲区中将发生 OB 0 缓冲区溢出事件。
为避免这种情况，如果未组态或连接关联OB，请不要在设备组态中组态信号沿条件。
你可以创建一个对应信号沿事件的硬件中断 OB，或者您可以在您的程序中通过ATTACH 指令将 OB 连接信号沿事件。
此外，请勿编程 DETACH 指令将信号沿条件从分配的 OB 或连接信号沿事件的 OB分离。
如果未给快速发生的信号沿条件分配 OB，将引发 OB 0 缓冲区溢出事件。
2016 年 9 月版 S7-1200 系统手册更新“模拟值的处理”更正S7-1200 可编程控制器系统手册 5.3 节“模拟值的处理”有关原始模拟信号电压上限为 27648的表述正确。
但在示例中（包括示例梯形图），错误将 24768 作为上限值。
请使用 27648 代替示例中所有的 24768。
信号模块 (SM) 上的状态 LED 表更正已更新章节 15.1“状态 LED”中的表 15-2 信号模块 (SM) 上的状态 LED，说明只有模拟量信号模块支持“现场侧电源关闭”的LED 指示灯。

SM 1231 AI 8 x TC 位的连接器引脚位置表更正更新了附录 A 中的表 A-168，从而显示正确的 X12 和 X13 引脚位置表格 2 SM 1231 AI 8 x TC 位 (6ES7231-5QF32-0XB0) 的连接器引脚位置RALRM（接收中断）指令的 TINFO 和 AINFO 参数说明TINFO 和 AINFO 是RALRM（接收中断）指令的 IN_OUT 参数。
您可以将这些参数结构存储在 PLC变量表或标准（非优化型）DB 中。
您不可以将其存储在本地块接口或优化的 DB 中。
如果 TINFO 或 AINFO结构位于本地块接口或优化 DB 中，RALRM 指令将不会在 TINFO 或 AINFO 参数中返回正确值且 STATUS 输出为 0。
