NI PXI-7831R卡件PLC控制模塊保護(hù)你的鑰匙。每個(gè)新的350–374 CPU都配有一對(duì)按鍵開(kāi)關(guān)。如果您使用上述一個(gè)或多個(gè)鑰匙開(kāi)關(guān)保護(hù)功能,我們建議您小心保護(hù)鑰匙。如果鑰匙丟失、放錯(cuò)地方或被盜,您可能會(huì)被鎖定無(wú)法使用PLC,未經(jīng)授權(quán)的人員可能會(huì)接觸到它??梢再?gòu)買零件號(hào)為44A736756-G01的替換鑰匙。NI PXI-7831R該套件包含三組CPU鍵。所有350–374個(gè)CPU使用相同的密鑰。當(dāng)然,您可以選擇不使用任何鑰匙開(kāi)關(guān)保護(hù)功能,在這種情況下,您可以將鑰匙開(kāi)關(guān)設(shè)置為斷開(kāi)位置,并將兩個(gè)可配置鑰匙開(kāi)關(guān)功能設(shè)置為默認(rèn)(禁用)設(shè)置。然后,您將不需要使用鍵來(lái)訪問(wèn)PLC。順序事件記錄器(SER)指令此功能指令(在梯形邏輯中編程)是在CPU固件9.0版中引入的,適用于所有具有此固件的350–374 CPU。SER的目的是提供動(dòng)態(tài)故障排除和調(diào)試工具。NI PXI-7831R
英文資料
Protect your keys. Each new 350–374 CPU is supplied with a pair of keys for the key switch. If you use one or more of the key switch protection features described above, we recommend you carefully guard your keys. If they are lost, misplaced, or stolen, you may be locked out from working on your PLC, and unauthorized persons may have access to it. Replacement keys can be purchased under part number 44A736756-G01. This kit contains three sets of CPU keys. All 350– 374 CPUs use the same key. Of course, you can choose to not use any of the keyswitch protection features, in which case you can leave the keyswitch set to the OFF position, and leave the two configurable keyswitch features set at their default (disabled) settings. Then, you will not need to use a key to access the PLC. Sequential Event Recorder (SER) Instruction This functional instruction (programmed in ladder logic) was introduced in CPU firmware release 9.0 and is available in all of the 350 – 374 CPUs that have this firmware. The purpose of the SER is to provide a dynamic troubleshooting and debugging tool.
