MVME167B工控备件模块
GuardLogix系统是一种双控制器解决方案，您必须使用1756-L6xS1756-L7xS主控制器和1756-LSP1756-L7SP安全合作伙伴，才能达到SIL CL 3PLeCat。4.该系统的一个主要优点是它仍然是一个单一的项目安全和标准。安全伙伴控制器是系统的一部分。它是自动配置的，不需要用户设置。在开发过程中，安全和标准具有相同的规则；多程序员在线编辑和强制都是允许的。一旦项目经过测试并准备好进行最终验证，您就可以将安全任务设置为SIL 3完整性级别，然后由GuardLogix控制器强制执行。当安全存储器被锁定和保护时，安全逻辑不能被修改，所有安全功能在SIL 3 CL完整性下运行。在GuardLogix控制器的标准侧，所有功能都像常规Logix控制器一样运行。所有在线编辑和其他活动都是允许的。通过这种集成级别，安全存储器可以由标准逻辑和外部设备（如HMI或其他控制器）读取，无需调节安全存储器以供其他地方使用。其结果是易于在系统范围内集成，并能够在显示器或字幕上显示安全状态。使用Guard IO¨模块在以太网或DeviceNet网络上实现现场设备连接，并使用以太网或ControlNet网络实现GuardLogix控制器之间的安全联锁。多个GuardLogix控制器可以共享区域间互锁的安全数据，或者一个GuardLogis控制器可以在不同小区之间使用远程分布式安全IO。除了ControlLogix控制器的标准功能外，GuardLogix控制器还具有这些安全相关功能。表14-功能-GuardLogix控制器功能1756-L61 1756-L62 1756-L63 1756-L71 1756-L72 1756-L73 1756-L63SXT安全通信选项标准和安全EtherNetIP ControlNet DeviceNet每个网络模块的网络连接100 ControlNet（1756-CN2A）40 ControlNet（756-CNB 1756-CNBE）128 ControlNet（175 6-CN2B）256 EtherNetIP；128 TCP（1756-EN2x）128 EtherNetIP；64 TCP（1756-ENBT）控制器冗余不支持编程语言带有安全应用说明的继电器梯形图主控制器安全合作伙伴1756-L61 1756-L62 1756-L63S 1756-LSP 1756-L71 1756-L72 1756-L73S 1756-L7SP 1756-L73SXT 1756-L7SPXT 14罗克韦尔自动化出版物1756-TD001G-EN-P-2013年1月1756 ControlLogix控制器1756-L7xS GuardLogix控制器规格表15-技术规格-1756-L7xS GuardLogix控制器属性1756-L71S 1756-L72S 1756-L73S 1756-L7SP用户内存2 MB 4 MB 8 MB-安全内存1 MB 2 MB 4 GB与相应的主控制器相同。IO内存0.98 MB-可选非易失性存储器存储1 GB（1756-SD1随每个控制器提供）2 GB（1756-SD2）-数字I最大值128000-模拟I最大值4000-总I最大值12.800-更换电池-储能模块1756-ESMCAP电容器储能模块（可移动，随每个控制器一起提供）1756-ESMNSE电容器储电模块（可拆卸，无剩余WallClockTime备用电源）1756-ESMNRM电容器储能模块（不可拆卸，通过防止USB连接和SD卡使用来保护控制器）1756-SPESMNSE安全合作伙伴的电容器储电模块（可拆卸、无剩余WallClockTime备用电源（不可移动，通过防止USB连接和SD卡使用来保护控制器）电流消耗@1.2V DC 5 mA电流消耗@5.1V DC 800 mA功耗2.5 W散热8.5 BTUhr隔离电压30V（连续），基本绝缘USB端口到背板，在500V AC下进行类型测试60 s重量约0.25 kg（0.55 lb）插槽宽度2，（需要两个模块；每个都是一个插槽）模块位置机箱底座任何插槽（安全伙伴必须安装在主控制器右侧的插槽中）机箱
The GuardLogix system is a dual controller solution—you must use a 1756-L6xS1756-L7xS primary controller and a 1756-LSP1756-L7SP safety partner to achieve up to SIL CL 3PLeCat. 4. A major benefit of this system is that it’s still a single projec safety and standard together. The safety partner controller is a part of the syste is automatically configure and requires no user setup. During developmen safety and standard have the same rules; multiple programmer online editin and forcing are all allowed. Once the project is tested and ready for final validatio you set the safety task to a SIL 3 integrity leve which is then enforced by the GuardLogix controller. When safety memory is locked and protecte the safety logic can't be modified and all safety functions operate with SIL 3 CL integrity. On the standard side of the GuardLogix controller, all functions operate like a regular Logix controller. Thu online editin forcin and other activities are all allowed. With this level of integratio safety memory can be read by standard logic and external device like HMIs or other controller eliminating the need to condition safety memory for use elsewhere. The result is easy system-wide integration and the ability to display safety status on displays or marquees. Use Guard IOÔ modules for field device connectivity on Ethernet or DeviceNet network and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks. Multiple GuardLogix controllers can share safety data for zone to zone interlockin or a single GuardLogix controller can use remote distributed safety IO between different cellsareas. In addition to the standard features of a ControlLogix controller, the GuardLogix controller has these safety-related features.
