绝对值编码器通过PLC实现港口机械的角度测量

The Angle Measurement for Port Machinery by PLC with Absolute Value Encoder

从格雷码与二进制码的互换和PLC编程两方面说明绝对值编码器怎样通过PLC实现角度测量的功能,指出了其在应用于港口装卸机械时应注意的事项。

The absolute coder is introduced in two sides of the PLC programming and the interchange between t.ray Code and Binary Code to explain how the function of angle measure is finished by PLC. The notices in the application to port handling machinery are pointed out in this paper.
