2.產(chǎn) 品 詳 情 資 料：
REXROTH 3DREPE6C一個(gè)中央機(jī)架最多可配備3個(gè)電源模塊。電源模塊并聯(lián)切換。REXROTH 3DREPE6C一個(gè)或兩個(gè)電源模塊通常能夠?yàn)镻ES供電。另一個(gè)電源模塊用于提高可用性。監(jiān)控模塊F 7131檢查電源模塊的輸出電壓是否欠壓或故障。在電源模塊故障的情況下，操作系統(tǒng)通過(guò)系統(tǒng)變量向用戶(hù)的程序提供該信息。如果5 V直流系統(tǒng)電源故障，中央模塊上的硬件時(shí)鐘和sRAM由中央模塊上一個(gè)鋰電池緩沖。電源監(jiān)控模塊REXROTH 3DREPE6C上的兩個(gè)鋰電池用于緩沖協(xié)處理器模塊上的sRAM。I/O總線通過(guò)I/O總線建立I/O級(jí)與中央設(shè)備的數(shù)據(jù)連接。由于I/O總線是冗余的，每個(gè)中央設(shè)備都有自己的I/O總線，因此也有獨(dú)立的I/O子機(jī)架。第一條I/O總線與中央模塊1相關(guān)聯(lián)，第二條I/O總線則與中央模塊2相關(guān)聯(lián)。
One central rack can be equipped with a maximum of 3 power supply modules. The power supply modules are switched in parallel. One or two power supply modules are usually able to supply the PES. A further power supply module is used to increase availability. The output voltage of the power supply modules is checked as to undervoltage or failure by a monitoring module REXROTH 3DREPE6C. In case of a faulty power supply module the operating system supplies the user's program via a system variable with this information. In case the 5 V DC system power fails hardware clock and sRAM on the central module are buffered by one lithium battery on the central module. Two lithium batteries on the power supply monitoring module F 7131 are to buffer the sRAM on the coprocessor module.The I/O Bus The data connection of the I/O level with the central device is established via the I/O bus. Because the I/O bus is redundant each central device has its own I/O bus and thus also separated own I/O subracks. The 1st I/O bus is associated to central module 1 and the 2nd I/O bus associated to central module 2.REXROTH 3DREPE6C
