IC695CRU320特別用于冗余或熱備用配置。使用此控制器配置，可提高可用性。兩個(gè)控制器機(jī)架，其配置功能與主（主動(dòng)）和輔助（備用）機(jī)架相似。當(dāng)單個(gè)機(jī)架發(fā)生故障時(shí)，主要是由于IC695CRU320檢測(cè)到的錯(cuò)誤或IC695CRU320處理器本身的錯(cuò)誤，主動(dòng)控制器占空比將自動(dòng)轉(zhuǎn)移到輔助。輔助機(jī)架成為主機(jī)架，故障機(jī)架轉(zhuǎn)移到輔助機(jī)架。此外，還可以手動(dòng)切換?？刂破髑袚Q在多1次邏輯掃描中執(zhí)行，小切換時(shí)間為3.133毫秒。它支持高達(dá)IC695RMX128/228的同步鏈路，并能夠傳輸高達(dá)2M字節(jié)的數(shù)據(jù)。支持兩個(gè)用于冗余的IC695RMX128/228同步鏈路。IC695CRU320的編程可以用梯形圖、C和功能框圖語(yǔ)言完成。通過(guò)基于機(jī)架的以太網(wǎng)通信模塊支持以太網(wǎng)通信。
IC695CRU320
The IC695CRU320 is especially used in redundant or hot standby configurations. Use this controller configuration to improve availability. Two (2) controller racks, configured to function similarly to the primary (active) and secondary (standby) racks. When a single rack fails, mainly due to an error detected by the IC695CRU320 or an error by the IC695CRU320 processor itself, the active controller duty cycle is automatically transferred to the auxiliary. The auxiliary rack becomes the host rack, and the faulty rack is transferred to the auxiliary rack. In addition, it can be switched manually. The controller switch is performed in one more logical scan with a small switch time of 3.133 ms. It supports synchronous links up to IC695RMX128/228 and is capable of transmitting up to 2M bytes of data. Supports two IC695RMX128/228 synchronous links for redundancy. Programming of the IC695CRU320 can be done in ladder diagram, C and function block diagram languages. Ethernet communication is supported through a rack-based Ethernet communication module.
