第二讲 COMPACTLOGIX的编程入门

RSLinx通讯软件。通过RSLinx可以实现PC机与CompactLogix控制器之间的通讯，也就是说要实现将通过RSLogix5000编写好的程序下载、上载或进行在线监控程序等都需要调用RSLinx。
BOOT-DHCP 服务器软件，通过它可以给以太网模块分配IP地址。新的以太网模块的IP地址都是设置为自动获取，如果你没有串口通讯电缆，通过这个软件可以发现以太网模块并设置其IP地址，之后可以通过以太网通讯。如果手上有串口通讯电缆，无需BOOT-Server也可以设置以太网网卡的IP地址，后面我们会以两种方式来介绍如何设置IP地址。
（下面部分要抓屏，视频文件：df1.wmv）如果已经安装了RSLinx软件，那么在默认情况下已经启动，可以点击托盘上的RSLinx图标，打开RSLinx窗口，点击RSLinx菜单的Communication，在Commnication子菜单上选择Configure Drivers，我们看到随后出现Configure drivers 窗口，从Avaliable Driver types，也就是可用的驱动类型列表框上选择你要通过什么接口来连接CompactLogix。因为我们这里是通过串口，所以选择RS232 DF1 device，再点击旁边的Add new 按钮，在随后的对话框上就使用其默认名字，点击OK按钮。接着，我们看到出现configure RS232 DF1 Devices对话框，在这里我们可以设置串口连接属性，比如可以设置串口号、串口通讯速率、校验类型等，这些参数要与CompactLogix的串口参数一样才能连上CompactLogix。虽然CompactLogix有默认的串口通讯参数，我们可能不记得了，那如何设置这些参数？其实，我们无需记住CompactLogix串口参数类型，因为RSLinx可以为我们自动检测CompactLogix串口参数类型。点击对话上的Auto-Config按钮开始自动设置串口参数，只要串口连接了设备，RSLinx就会自动检测出CompactLogix串口参数并设置这个驱动参数使其与CompactLogix相匹配。我们看到RSLinx已经成功地自动配置参数，点击OK按钮退出串口参数配置对话，再点击Close按钮完成添加串口驱动。

第三讲 CompactLogix的编程介绍

第三讲 CompactLogix的编程介绍通过前一讲我们已经初步知道了如何使用RSLinx和RSLogix5000，这一讲我们将介绍CompactLogix的程序结构、编程语言、自定义数据结构、Add-on自定义指令、模拟量模块以及一些指令的使用。

一．程序结构和编程语言CompactLogix的程序结构分为任务-程序-子程序三级结构，每个CompactLogix控制器可以有多个任务，不同控制器类型的任务数是不同的,比如CompactLogix 1768系列有16个任务，而1769-L35E有8个任务。

任务是CompactLogix 的第一级程序结构，任务分成三种类型，包括连续型任务、周期型任务和事件型任务。

当控制器的CPU没有执行其它操作时，CPU执行连续型任务，连续型任务执行完毕后，又从头开始执行。

连续型任务的执行是周而复始的过程，它的执行周期是不定的优先级比周期性任务和事件型任务都低。

一个CompactLogix工程项目可以没有连续型任务，最多也只能有一个连续型任务。

用于工厂自动化的顺序控制系统通常都有连续型任务，而对于过程控制的系统，则可能没有连续型任务。

周期型任务就如它的名字一样是按照预先设定的时间间隔执行的任务。

CompactLogix控制器是个多任务的系统，但是在某一时刻只能执行一个任务。

如果某一个任务正在执行，此时另一个任务要被触发执行，这时控制器就要看看这两个任务的优先级，以决定是否中断正在执行的任务，转而去执行其它任务。

CompactLogix具有15个优先级，数值从1-15，数值小的优先级高。

优先级高的任务可以中断优先级低的任务，执行完优先级高的任务后再回头从低优先级任务中断处继续执行，连续型任务的优先级最低，它可被其它任务所中断。

第三种任务类型是事件型任务，当一个指定的触发事件发生时才去执行事件型任务。

在创建事件型任务时可以指定这种触发事件，触发事件有多种，比如有数字量信号发生变化时，运动控制执行某种操作时，消费者标签接收到数据时或是通过事件指令来触发等。

CompactLogix系统概述

CompactLogix系统概述CompactLogix提供了一个从单机到分布式应用系统的Logix解决方，案。

其中1769-L35E控制器不仅具有增强的处理性能，支持多达30个的本块1769 I/O模块，还内置有可进行实时I/O控制的100Mbps EtherNet/IP网络接口，与包括1769 I/O模块在内的多种I/O模块在内的多种I/O模块一起实现分布式I/O扩展。

一个最简单的CompactLogix单机系统可以只由一个独立的控制器一组I/O模块和电源组成。

CompactLogix控制器可与其他控制器一起构成分布式控制系统：多个控制器通过网络连接在一起，进行通讯和数据共享。

每个CompactLogix控制器可以通过DeviceNet或EtherNet/IP（仅1769-L3XE控制器），使用各种不同系列的I/O进行分布式扩展。

对于1769Compact I/O每个I/O站可支持最多3个I/O模块组，最多30个模块。

支持多层网络的无缝集成和数据路由。

这意味着用户可以方便地自动实现跨多层网络的远程设备访问，组态和诊断。

例如：在控制室布置的1769-L35E CompactLogix控制器，通过DeviceNet现场总线连接现场的变频器、软启动、行程开关等智能设备，通过EtherNet/IP 连接上位机。

则用户无需附加编程，即可在上位机上直接对布置在现场的变频器进行远程组态。

规划控制当您规划控制系统时，需要确定是单机系统还是分布式控制系统。

如果是分布式控制系统，则应选择所使用的联网方式和类型、控制器的类型数量和安装位置以及I/O模块的类型、数量和安装位置。

如前所述，多哥CompactLogix系统可以通过EtherNet/IP、DeviceNet或DH-485与上位机及其他控制器进行联网。

并且，每个CompactLogix控制器可通过EtherNet/IP（仅1769-L3XE控制器），或DeviceNet网络控制远程I/O和现场设备。

第二讲CompactLogix的编程入门

第二讲 CompactLogix的编程入门在前一讲中，咱们已经介绍了CompactLogix的硬件系统组成，还介绍了L3和L4系列的安装，在这一讲咱们要进行CompactLogix的大体编程，需要用到三个软件，虽说是三个软件可是却只有一个软件包即RSLogix5000编程软件包提供：RSLogix 5000编程软件。

所有的Logix系列控制器都用这个编程软件来编程，RSLogix5000编程软件符合IEC61131标准，包括四种编程语言：梯形图、功能块、顺序流程图和结构化文本。

RSLinx通信软件。

通过RSLinx可以实现PC机与CompactLogix控制器之间的通信，也就是说要实现将通过RSLogix5000编写好的程序下载、上载或进行在线监控程序等都需要挪用RSLinx。

BOOT-DHCP 服务器软件，通过它可以给以太网模块分派IP地址。

新的以太网模块的IP地址都是设置为自动获取，若是你没有串口通信电缆，通过这个软件可以发现以太网模块并设置其IP地址，以后可以通过以太网通信。

若是手上有串口通信电缆，无需BOOT-Server 也可以设置以太网网卡的IP地址，后面咱们会以两种方式来介绍如何设置IP地址。

在这一讲，咱们要组态的模块有一个1769-L35E、一个开关量输入模块1769-IQ16和一个开关量输出模块1769-OB8。

1769-L35E模块集成了EtherNet/IP通信接口，就象前面已经提及的，在工厂默许情况下，EtherNet/IP网络接口的IP地址设置为自动获取IP地址，所以如要利用EtherNet/IP 接口，需要先设置其IP地址。

下面我以两种方式来设置IP地址。

一．通过串口通信电缆设置IP地址首先，咱们将已安装的CompactLogix上电，并通过串口通信电缆连接CompactLogix的串口和PC机串口。

前面已经提到，RSLinx是通信软件，在这里咱们就要利用RSLinx设置CompactLogix L35E 集成以太网模块的IP地址。

第一讲 CompactLogix 硬件系统

第一课CompactLogix 硬件系统罗克韦尔自动化集成架构是一种工业自动化体系架构，它可为制造商、OEM设备厂商以及系统集成商提供了全方位、可扩展的解决方案，有别于其它任何系统，集成架构使用一个通用的包括多种控制策略的引擎，一个开发环境，一个网络协议和一个面向服务架构（SOA）。

集成架构能够胜任多种自动化控制任务，包括顺序控制、运动控制、过程控制、批次控制、传动控制和安全控制等。

集成架构的控制引擎即Logix控制引擎，包括ControlLogix、CompactLogix、SoftLogix和DriveLogix等各种控制器，这些控制器有各种不同型号适合不同规模的控制。

其中CompactLogix是一种中型的控制器，尤其适合中高端OEM机器的控制。

CompactLogix包括L2系列、L3系列和L4系列3个系列的控制器。

(展示这几种控制器实物) 其中L2和L3系列是1769总线，在本地机架或本地扩展只能使用1769的模块。

L4系列是1768总线，它可以使用1768和1769总线的模块。

CompactLogix控制器不是采用框架安装，CompactLogix各模块之间是采用总线插销来连接相邻模块，CompactLogix的模块安装灵活，不受机架限制，可直接从前部插入/拔出，减少安装和更换的时间，本地扩展方便：仅仅通过一根带左右盖板的电缆就完成扩展，不需要增加通讯模块就可以完成本地扩展，节省扩展成本等等。

安装方式采用标准D型导轨卡装，同时也可以对每一个模块进行螺丝固定。

另外，模块尺寸更小，节省安装空间等。

所有的CompactLogix 控制器上都集成了一个串口，有的控制器上还集成有ControlNet或EtherNet/IP接口，可以通过型号来看是否集成了其它网络接口，如1769-L32E这是个L3系列的控制器，它还集成了一个以太网接口，1769-L35CR，这是个L3系列的控制器，它集成了双通道的ControlNet 接口。

If you update the firmware of a controller while it is connected to a DH-485 network, communication on the network may stop.If The Controller ThenDoes not use a CompactFlash card Save the project to an offline file. When you update the firmware of the controller, you erase the contents of the nonvolatile memory (revision 10.x or later).Uses a CompactFlash cardEither:•Remove the CompactFlash card from the controller.•Check the Load Image option of the CompactFlash card. If it is set to On Power Up or On Corrupt Memory, first store the project with the Load Image option set to User Initiated.Otherwise, you may get a major fault when you update thefirmware of the controller. This occurs because the On Power Up or On Corrupt Memory options cause the controller to load the project from nonvolatile memory. The firmware mismatch after the load then causes a major fault.AnomalyDescriptionLimitsInv and SelectLimitInv are swapped.In the High/Low Limit (HLL) instruction:•LimitsInv parameter is set when the SelectLimit is invalid•SelectLimitInv parameter is set when the HighLimit and LowLimit parameters are invalid.Lgx00055977CompactLogix Controllers, Revision 15 Release Notes 3 Corrected Anomalies This revision of CompactLogix controllers corrects these anomalies. Corrected Anomaly DescriptionGenerated faults on the 1769-L3x controller held outputs in their last state rather than turning outputs off.With the 1769-L3x CompactLogix controller, firmware revisions 15.01 to 15.03, the following functional issue existed:With a 1769-L3x controller, if 1769 I/O backplane faults or certain I/O module hardware faults occur, outputs were held in their last state at the time of the fault condition rather than the outputs turning off. This only occurred with 1769 I/O backplane faults and certain I/O module hardware faults such as loss of backplane termination or loss of 24V on an analog module configured to use external 24V and not with general controller faults such as a Watchdog timeout.This behavior is contrary to the information in the CompactLogix System User Manual, publication 1769-UM011. To correct this issue update the 1769-L3x controller firmware. The functional issue described above has been corrected in the 1769-L3x CompactLogix controller, firmware revision 15.04.Lgx00059797The Batch recipe became inoperative.If two PXRQ instructions that had been triggered on the same Phase were received by thebatch server before the first PXRQ completes the Batch recipe became inoperative.Lgx00056918MS light blinked red when going from version 13 to 15 on L32E and L35E products.Because the Ethernet card took longer to respond to the controller when receiving data, a timer value has been increased.Lgx00059331RSLogix 5000 software reported that POINT I/O connections were not scheduled even though they were scheduled and working on the network. After associating the RSNetWorx for ControlNet file in RSLogix 5000 and scheduling the network, RSLogix 5000 software displayed an error while trying to save the configuration. The error stated that the POINT I/O connections were not scheduled even though they clearly were and working properly on the network.If you made changes to the program that didn’t involve ControlNet changes, and then downloaded, you had to reschedule the ControlNet network. The work around was to remove the association before you saved. Revision 15.4 removes the need for this work around.Lgx00058517PXRQ Instruction sometimes stayed in process and did not complete.When executing phase request messages to a batch server, the PXRQ instruction would sometimes stay in process (IP bit set) and never complete. The same scenario could have occurred if the user took ownership of a phase from Logix5000 while a PXRQ instruction was in process. The only recovery method was to transition from program to run or to cycle power to the controller.Lgx00058484, 58631, 59317, 58390, 57760An Attempt to Abort a Phase Request (PXRQ) caused all PXRQ's not to function.If the abort bit was set in a PXRQ instruction with the IP or WA bit set, all remaining PXRQ's in the phase would stop operating correctly. Recovery from this situation required that you download the program again or to cycle power to the controller.Lgx00058678CompactFlash LED When accessing the CompactFlash card the CF LED did not operate as expected.Lgx00045715Publication 1769-RN015C-EN-E - February 20094 CompactLogix Controllers, Revision 15 Release NotesPrevious Release Notes These release notes correspond to the controller revision 15.03.Known Issues•With a 1769-L31 controller, you cannot bridge from one serial port tothe other. You can bridge from either serial port to DeviceNet networkvia the 1769-SDN scanner.•Tasks are the basic scheduling mechanism for executing a program andare created as part of the project and program creation process. Inaddition to other internal tasks, the CompactLogix controllers have aninternal task to provide communication with the 1769 I/O modules.This task executes periodically at the Requested Packet Interval (RPI)selected in the properties of the CompactBus. If the task has notcompleted before it is time to execute again, a task overlap occurs. Thistask overlap causes the controller to declare a minor fault of Type = 6(Task Overlap), Code = 4 (VA task).You can use various strategies to resolve minor faults due to taskwatchdog timeout and/or task overlap. For more information, seeRSLogix5000 Online Help “Identifying and Managing Tasks”. In thecase of a minor fault caused by VA task overlap, increase the RPI untilthe overlap no longer occurs.•If a 1769 I/O fault occurs, you must cycle power to the CompactLogixcontroller after clearing the major fault. I/O communications are notrestored until after the power cycle. You should never use the faulthandling routine to clear local I/O faults. You should clear local I/Ofaults manually on a per case basis, and then the controller should bepower cycled.Publication 1769-RN015C-EN-E - February 2009Publication 1769-RN015C-EN-E - February 2009CompactLogix Controllers, Revision 15 Release Notes 5EnhancementsThis revision of CompactLogix controllers adds these enhancements:•The PhaseManager option provides a state model for your equipment. It includes:–equipment phase to run the state model.–PHASE data type.–equipment phase instructions (relay ladder and structured text only).•Support for 32 programs and equipment phases (combined) per task •In function block diagram instructions, DeltaT for periodic timing in a periodic task now includes fractional values.•1769-L32E and 1769-L35E only–Support for duplicate IP address detection. When you change the IP address or connect one of these controllers to an EtherNet/IP network, the controller checks to make sure that the IP addressassigned to this controller is not the same as that for any other device already on the network.–Support for Dynamic Host Configuration Protocol (DHCP)software.

Message packets are now limited to 240 bytes. This could cause some MSG instructions that worked in previous firmware revisions to not work in revision 15 firmware.For example, use a CIP Generic MSG instruction to perform a Get Attribute Single service. The attribute is 4 bytes in length. Assume the destination tag is an INT data type (2 bytes in length). In revision 13 firmware, the MSG instruction places the first 2 bytes of the attribute in the destination tag. In revision 15 firmware, the MSG instruction errors because the destination tag is not large enough. To correct this error, change the destination tag to a DINT data type.Lgx00052504The File Search Compare (FSC) instruction caused a non-recoverable faultThe FSC instruction caused an non-recoverable fault if both of these conditions occurred:•A major fault was declared from within the expression of an FSC instruction •The user fault routine cleared the faultWhen the user fault routine attempted to recover, information previously saved was not properly restored, which resulted in corrupted system registers and a non-recoverable fault.Lgx00055522Programmatic change of MSG status bits could cause the MSG to appear to remain active (EN Set)If you programmatically reset the DN or ER bits of a MSG due to the asynchronous nature of the MSG, the MSG could appear to remain active (EN set). In fact, the MSG was not active. The MSG required manual intervention to trigger it to execute again. Revision 15 removes the need for manual intervention to trigger the MSG to execute again.Lgx00053112Publication 1769-RN015C-EN-E - February 2009CompactLogix Controllers, Revision 15 Release Notes 7An SFC could execute the wrong stepIf you had an SFC with nested simultaneous branches, the controller could begin execution at an unexpected step. Following the convergence of a nested simultaneous branch, if the SFC looped back to the initial step of the parent branch, instead of executing that step, the SFC could jump to a step of another path in the nested simultaneous branch. For example:Execution starts at Step_000. When Tran_000 becomes true, Step_001, Step_002 and Step_003 should become active. However, because the nested simultaneous branch in the left path converged and looped back to its parent step (Step_001), the active steps were actually Step_005, Step_002 and Step_003.Lgx000542471769-L32E and 1769-L35E cleared user program if too many messages were sent on the EtherNet/IP networkOccasionally, the 1769-L32E and 1769-L35E controllers cleared their user programs if an high number of messages were sent on EtherNet/IP network.Lgx00056184Controller failed to connect to a 1769-ASCII module if the module immediately followed a 1769-SDN Module If your application used any of the CompactLogix controllers and you set-up your local I/O rail with a 1769-ASCII module immediately following a 1769-SDN scanner, the CompactLogix controller failed to make a connection to the 1769-ASCII module.Lgx00053778Corrected AnomalyDescriptionPublication 1769-RN015C-EN-E - February 20098 CompactLogix Controllers, Revision 15 Release NotesRestrictionsThis revision of CompactLogix controllers has these restrictions.RestrictionDescriptionIn a tag of a user-defined data type, an instruction may write past the end of anarray.If you write too much data to an array that is within a user-defined data type, someinstructions write beyond the array and into other members of the tag.The following instructions write beyond the array into other members of the tag:This restriction also applies to all previous revisions.To prevent writing beyond the limits of the destination array, make sure the length operand of the instruction is less than or equal to the number of elements in the array.Lgx00033747If the length is greater than the numberof elements in the destination array……the instruction stops at the end of the array.Example 1: InstructionStops at the End of the ArrayIf the length is greater than the number of elements in the destination array……the instruction writes data beyond the end of the array into other members of the tag. Regardless of the length specified for the instruction, it stops writing if it reaches the end of the tag.Example 2: Instruction Writes Beyond the Array BSL BSR COP CPS DDTFBC FFL FFU FLL GSVLFL LFU SQL SRT SSVCompactLogix Controllers, Revision 15 Release Notes 9Load Controller Firmware The controller ships without working firmware.
