REXROTH VT3000S34-R5一個(gè)I/O機(jī)架包含：–最多4個(gè)配電模塊，用于保護(hù)輸入/輸出電路–一個(gè)耦合模塊，用于連接I/O總線，在發(fā)生故障時(shí)，看門(mén)狗信號(hào)可自動(dòng)安全關(guān)閉–最多16個(gè)插槽，用于數(shù)字和模擬信號(hào)的輸入和輸出模塊。安全關(guān)閉的概念在發(fā)生輸出故障時(shí)，在安全相關(guān)PES H51q MS、-HS、-HRS的系統(tǒng)描述中，顯示了發(fā)生故障時(shí)關(guān)閉的方式。系統(tǒng)的反應(yīng)是固定的，或者可以通過(guò)構(gòu)建塊H8-STA-3和激活緊急關(guān)閉的系統(tǒng)變量在用戶程序中定義。操作過(guò)程中對(duì)安全相關(guān)I/O模塊故障的反應(yīng)：輸出模塊單一錯(cuò)誤（也包括電壓降）模塊關(guān)閉1）每組一個(gè)構(gòu)建塊H8-STA-3組關(guān)閉2）緊急關(guān)閉系統(tǒng)變量激活關(guān)聯(lián)CU的WD關(guān)閉3）REXROTH VT3000S34-R5I/O機(jī)架內(nèi)的I/O總線或輸出模塊雙重故障WD關(guān)閉關(guān)聯(lián)IO-CON 4）系統(tǒng)變量緊急關(guān)閉激活的WD關(guān)閉相關(guān)CU 3）中央模塊（CU）或I/O總線。CU和IOCON WD關(guān)閉相關(guān)CU輸入模塊該模塊所有輸入的0信號(hào)操作REXROTH VT3000S34-R5
One I/O rack contains: – Up to 4 power distribution modules to protect the input/output circuits – One coupling module to connect the I/O bus, with fail-safe switch off of the watchdog signal in the case of a fault – A maximum of 16 slots for input and output modules for digital and analogue signals.Conceptions of the Safety Switch Off In case of faults of output, coupling and central modules and group switch off In the system REXROTH VT3000S34-R5descriptions of the safety related PES H51q-MS, -HS, -HRS the ways for shut down if a fault occurs are shown. The reactions of the systems are fixed or they can be defined in the user’s program by means of the building block H8-STA-3 and with activating of a system variable for emergency off. Reaction to faults of safety related I/O modules during operation:Output module Single error (also voltage drop) Module switch-off 1) One building block H8-STA-3 per group Group shut down 2) System variable for emergency off activated WD switch-off of the appertaining CU 3) I/O bus within I/O rack or double fault of output modules WD switch-off of the appertaining IO-CON 4) System variable for emergency off activated WD switch-off of the appertaining CU 3) Central module (CU) or I/O bus betw. CU and IOCON WD switch-off of the appertaining CU Input module Operation of 0 signal for all inputs of this moduleREXROTH VT3000S34-R5
