IS200DTAIH1A工控模塊機(jī)器人備件
控制模塊
DeltaV控制模塊同樣參考單工和冗余I/O通道，并且不需要特殊配置來(lái)利用冗余。冗余I/O卡的切換在I/O總線的兩次掃描內(nèi)完成。先接通后斷開(kāi)觸點(diǎn)，確保數(shù)字現(xiàn)場(chǎng)儀表保持通電，且過(guò)程不受干擾。在板卡切換期間，模擬輸出信號(hào)由兩個(gè)板卡短暫驅(qū)動(dòng)<5 ms。硬件警報(bào)自動(dòng)報(bào)告主卡和輔助卡的硬件完整性錯(cuò)誤。任何導(dǎo)致切換的事件也會(huì)通過(guò)系統(tǒng)硬件警報(bào)自動(dòng)報(bào)告，并記錄在事件記錄中。
硬件故障
可能導(dǎo)致切換的事件包括。活動(dòng)卡中的硬件故障。活動(dòng)卡和控制器之間的通信故障。現(xiàn)場(chǎng)接線故障檢測(cè)。也可以從診斷資源管理器啟動(dòng)切換，并且兩個(gè)卡及其通道的運(yùn)行狀況和狀態(tài)在診斷資源管理中可用。系統(tǒng)會(huì)自動(dòng)委托一張新的備用卡。在安全區(qū)域，故障卡可以在電源下更換。在危險(xiǎn)區(qū)域，必須遵循適當(dāng)?shù)陌惭b程序。硬件規(guī)范所有I/O接口的通用環(huán)境規(guī)范類別規(guī)范工作溫度*-40至70°C（-40至158°F）存儲(chǔ)溫度-40至85°C（-40至185°C）相對(duì)濕度5至95%，非冷凝空氣傳播污染物ISA-S71.04-1985空氣傳播污染物G3類共形涂層防護(hù)等級(jí)IP 20沖擊10 g?正弦波11 ms振動(dòng)1 mm峰間頻率為5至16 Hz；0.5 g（16至150 Hz）尺寸H 10.7 cm（4.2 in.）W 4.1 cm（1.6 in.）深度10.5 cm（4.1 in.）*長(zhǎng)時(shí)間在較高溫度范圍內(nèi)操作任何電子設(shè)備都會(huì)縮短其預(yù)期壽命，有關(guān)更多信息
control module
The DeltaV control module also refers to simplex and redundant I/O channels, and does not require special configuration to make use of redundancy. The switching of redundant I/O cards is completed within two scans of the I/O bus. Make and then disconnect the contacts to ensure that the digital field instrument is powered on and the process is not disturbed. During board switching, the analog output signal is briefly driven by two boards for<5 ms. Hardware alerts automatically report hardware integrity errors for both primary and secondary cards. Any event that causes switching will also be automatically reported through the system hardware alarm and recorded in the event log.
Hardware failure
Events that may cause switching include. Hardware failure in active card. Communication failure between active card and controller. Field wiring fault detection. You can also start the switch from Diagnostic Explorer, and the health and status of the two cards and their channels are available in Diagnostic Explorer. The system will automatically entrust a new spare card. In the safe area, the faulty card can be replaced under the power supply. In hazardous areas, proper installation procedures must be followed.
