在絕對(duì)位置檢測(cè)方面TR Electronic具有與長(zhǎng)，CD_582+FS 系列經(jīng)驗(yàn)證的 SIL 編碼器可不 CANopen 安全接口一起使用了。迄今為止 TR 已推出基于以太網(wǎng)的 PROFINET / Profilesafe、帶有 CIP Safety?的Ethernet/IP、FSoE（通過EtherCAT的故障保護(hù)）和 Powerlink open SAFETY。

不這些接口丌同，CANopen Safety 根據(jù)“白色通道原理”工作，即在對(duì)整個(gè)應(yīng)用程序的安全評(píng)估中，整個(gè)信號(hào)路徑必須證明其可靠性。這是通過重復(fù)傳輸和使用底層 CSMA/CA（防撞）協(xié)議來實(shí)現(xiàn)的，該協(xié)議構(gòu)成了所有CAN 實(shí)現(xiàn)的基礎(chǔ)。

安全編碼器的接口連接已經(jīng)通過廣泛的測(cè)試證明了其可靠性，掃描技術(shù)也經(jīng)過了無數(shù)次測(cè)試，不所有 CD_582+FS 一樣。該模塊化系統(tǒng)基于最新技術(shù)，使標(biāo)準(zhǔn)產(chǎn)品組合中的編碼器能夠完美地適合應(yīng)用。機(jī)械連接可通過實(shí)心軸、盲孔軸、空心軸實(shí)現(xiàn)。根據(jù)安全相關(guān)測(cè)量系統(tǒng)的要求，驅(qū)動(dòng)軸的正向鎖定通過鍵槽連接固定，或通過由彈簧鋼制成的扭矩支架，用于空心軸和盲孔軸固定。

具有 CANopen Safety 的 CD_582+FS 緊湊型安全編碼器，可以在軸丌靜止的情況下預(yù)設(shè)位置值。這種“動(dòng)態(tài)預(yù)設(shè)”的工作原理類似于電子參考——根據(jù)請(qǐng)求，輸出值將調(diào)整為先前存儲(chǔ)的預(yù)設(shè)值。錯(cuò)誤檢測(cè)，如設(shè)備故障，通常在 CANopen Safety 中由控制器對(duì)缺乏通信協(xié)議做出反應(yīng)來指示。CD_582+FS 也具有主動(dòng)故障安全狀態(tài)，即它們可以主動(dòng)向控制器報(bào)告發(fā)生的錯(cuò)誤?？刂破骺梢愿斓刈龀龇磻?yīng)（無需等待監(jiān)測(cè)時(shí)間）：例如，如果測(cè)量通道仍然可用，控制單元可以使用一個(gè)通道上確定的位置值移動(dòng)到停車位置。

安全編碼器掃描技術(shù)可供選擇，給用戶提供了較高的自由度，無論是全磁掃描還是光學(xué)位置檢測(cè)、快速高分辨率掃描。安全編碼器都可用于 SIL2/PLd 或 SIL3/PLe 的應(yīng)用。具有光學(xué)掃描選項(xiàng)的設(shè)備有一個(gè)特殊功能：除了安全總線系統(tǒng)外，位置值還通過 SSI 或增量接口輸出（不安全無關(guān)）。例如，該附加接口可以用于提供次級(jí)控制回路，而丌必經(jīng)過控制系統(tǒng)。同時(shí)，編碼器通過標(biāo)準(zhǔn)協(xié)議中的“灰色”通道提供直接測(cè)量值，無需額外保護(hù)。

CD_582+FS SIL安全編碼器，尤其是TR Electronic新推出的 CANopen Safety，使安全相關(guān)編碼器的決策變得非常容易：相同的安裝空間，相當(dāng)高的安全性。
