2.产 品 详 情 资 料：
REXROTH 3DREPE6C一个中央机架最多可配备3个电源模块。电源模块并联切换。REXROTH 3DREPE6C一个或两个电源模块通常能够为PES供电。另一个电源模块用于提高可用性。监控模块F 7131检查电源模块的输出电压是否欠压或故障。在电源模块故障的情况下，操作系统通过系统变量向用户的程序提供该信息。如果5 V直流系统电源故障，中央模块上的硬件时钟和sRAM由中央模块上一个锂电池缓冲。电源监控模块REXROTH 3DREPE6C上的两个锂电池用于缓冲协处理器模块上的sRAM。I/O总线通过I/O总线建立I/O级与中央设备的数据连接。由于I/O总线是冗余的，每个中央设备都有自己的I/O总线，因此也有独立的I/O子机架。第一条I/O总线与中央模块1相关联，第二条I/O总线则与中央模块2相关联。
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
