Big-Endian ConfigurationA signed byte load expects data on data bus inputs 31 through to 24 if the supplied address is on aword boundary, on data bus inputs 23 through to 16 if it is a word address plus one byte, and so on.

大尾段配置阿签署字节负载预计在31日的数据总线输入数据，如果通过向24所提供的地址上的字的边界，数据总线投入23日至16如果它是一个字地址加上一个字节，依此类推。

The system adopts CPU board with fast processing elevator operational program, data signal exchange, and HMI screen, which can make sure reliable operation and high speed. It also has PHILIPS SJA1000T field CAN bus, 82C251 Bus interface and the latest serial storage technique to record data. The functions of external watchdog and control chip internal watchdog compose two-level procedure monitoring, so as to ensure the normal operation of the control program. Heavy-current switch power LM2576 ensures the stable system working power, which has low requirements for the power supply. High-speed optoelectronic isolator and internal frequency division technology can make NW3P08-41C (42C) CPU receive the input impulse up to 1-phase 100 KHZ*2 CHANEL or 2-phase 50KHZ*1 CHANEL 32bit.
