GuardLogix系統是一種雙控制器解決方案，您必須使用1756-L6xS1756-L7xS主控制器和1756-LSP1756-L7SP安全合作伙伴，才能達到SIL CL 3PLeCat。4.該系統的一個(gè)主要優(yōu)點(diǎn)是它仍然是一個(gè)單一的項目安全和標準。安全伙伴控制器是系統的一部分。它是自動(dòng)配置的，不需要用戶(hù)設置。在開(kāi)發(fā)過(guò)程中，安全和標準具有相同的規則；多程序員在線(xiàn)編輯和強制都是允許的。一旦項目經(jīng)過(guò)測試并準備好進(jìn)行最終驗證，您就可以將安全任務(wù)設置為SIL 3完整性級別，然后由GuardLogix控制器強制執行。當安全存儲器被鎖定和保護時(shí)，安全邏輯不能被修改，所有安全功能在SIL 3 CL完整性下運行。在GuardLogix控制器的標準側，所有功能都像常規Logix控制器一樣運行。所有在線(xiàn)編輯和其他活動(dòng)都是允許的。通過(guò)這種集成級別，安全存儲器可以由標準邏輯和外部設備（如HMI或其他控制器）讀取，無(wú)需調節安全存儲器以供其他地方使用。其結果是易于在系統范圍內集成，并能夠在顯示器或字幕上顯示安全狀態(tài)。使用Guard IO¨模塊在以太網(wǎng)或DeviceNet網(wǎng)絡(luò )上實(shí)現現場(chǎng)設備連接，并使用以太網(wǎng)或ControlNet網(wǎng)絡(luò )實(shí)現GuardLogix控制器之間的安全聯(lián)鎖。多個(gè)GuardLogix控制器可以共享區域間互鎖的安全數據，或者一個(gè)GuardLogis控制器可以在不同小區之間使用遠程分布式安全IO。除了ControlLogix控制器的標準功能外，GuardLogix控制器還具有這些安全相關(guān)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安全通信選項標準和安全EtherNetIP ControlNet DeviceNet每個(gè)網(wǎng)絡(luò )模塊的網(wǎng)絡(luò )連接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）控制器冗余不支持編程語(yǔ)言帶有安全應用說(shuō)明的繼電器梯形圖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羅克韋爾自動(dòng)化出版物1756-TD001G-EN-P-2013年1月1756 ControlLogix控制器1756-L7xS GuardLogix控制器規格表15-技術(shù)規格-1756-L7xS GuardLogix控制器屬性1756-L71S 1756-L72S 1756-L73S 1756-L7SP用戶(hù)內存2 MB 4 MB 8 MB-安全內存1 MB 2 MB 4 GB與相應的主控制器相同。IO內存0.98 MB-可選非易失性存儲器存儲1 GB（1756-SD1隨每個(gè)控制器提供）2 GB（1756-SD2）-數字I最大值128000-模擬I最大值4000-總I最大值12.800-更換電池-儲能模塊1756-ESMCAP電容器儲能模塊（可移動(dòng)，隨每個(gè)控制器一起提供）1756-ESMNSE電容器儲電模塊（可拆卸，無(wú)剩余WallClockTime備用電源）1756-ESMNRM電容器儲能模塊（不可拆卸，通過(guò)防止USB連接和SD卡使用來(lái)保護控制器）1756-SPESMNSE安全合作伙伴的電容器儲電模塊（可拆卸、無(wú)剩余WallClockTime備用電源（不可移動(dòng)，通過(guò)防止USB連接和SD卡使用來(lái)保護控制器）電流消耗@1.2V DC 5 mA電流消耗@5.1V DC 800 mA功耗2.5 W散熱8.5 BTUhr隔離電壓30V（連續），基本絕緣USB端口到背板，在500V AC下進(jìn)行類(lèi)型測試60 s重量約0.25 kg（0.55 lb）插槽寬度2，（需要兩個(gè)模塊；每個(gè)都是一個(gè)插槽）模塊位置機箱底座任何插槽（安全伙伴必須安裝在主控制器右側的插槽中）機箱
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 IO? 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.
