NI PXI-2593多路復(fù)用器開關(guān)模塊中文資料：
NI PXI-2593多路復(fù)用器開關(guān)模塊CPU350和CPU360硬件功能這兩個(gè)模塊除了標(biāo)簽外看起來完全相同。這些模塊具有一個(gè)LED燈，標(biāo)記為“PS端口”，通過PLC電源上的串行連接器指示串行端口活動。通常，當(dāng)通過端口傳輸數(shù)據(jù)時(shí)，此LED將閃爍，當(dāng)端口處于非活動狀態(tài)時(shí)，此指示燈將熄滅。?這些模塊還具有本章前面所述的按鍵開關(guān)，這是350–364 CPU的標(biāo)準(zhǔn)配置。CPU固件升級存儲在閃存中的CPU固件通過PLC電源上的串行端口連接器加載。CPU351、CPU352和CPU363硬件功能這三個(gè)模塊的功能和功能相似。CPU351和CPU352看起來完全相同，只是標(biāo)簽不同。CPU363具有與其他兩個(gè)相同的功能，但其端口1和端口2連接器的方向與CPU351和CPU352的方向相反，其LED指示燈、按鍵開關(guān)和屏蔽接地連接器位于不同的位置。（屏蔽接地連接器位于CPU363的前面板上，標(biāo)有“FRAME”，但位于CPU351和CPU352模塊的底部。）NI PXI-2593
英文資料
CPU350 and CPU360 Hardware Features These two modules look identical except for labeling.These modules feature an LED light, labeled “PS Port” that indicates serial port activity through the serial connector on the PLC power supply. Typically, this LED will flash while data is being transferred through the port, and will stay off when the port is inactive. ? These modules also have the keyswitch, described earlier in this chapter, that is standard on the 350–364 CPUs. CPU Firmware UpgradeNI PXI-2593The CPU firmware, which is stored in Flash memory, is loaded through the serial port connector on the PLC Power Supply.CPU351, CPU352, and CPU363 Hardware Features These three modules are similar in features and functionality. The CPU351 and CPU352 look identical except for labeling. The CPU363 has the same features as the other two, but the orientation of its Port 1 and Port 2 connectors is reversed from those of the CPU351 and CPU352, and its LED indicator lights, key switch, and shield ground connector are in different locations. (The shield ground connector is on the front panel of the CPU363, labeled “FRAME,” but is located on the bottom of the CPU351 and CPU352 modules.)NI PXI-2593
