如上图我们就可以显示天车两腿的移动距离，同时如果加上可编程控制器的输出部分可实现系统的闭环控制，以实现自动控制和安全生产的目的。

原理：

两个（或者多个）CANOPEN编码器与可编程控制器通信，并且仪表显示，同时可以模拟量或者开关量输出。

此解决方案的优点：

1. 和串行总线SSI信号相比，传输距离更远。国际通用的SSI信号是100米左右，而CANOPEN总线远远大于这个距离

2. 多圈 值编码器断电保存，停车检修方便

3. 因为现场的动力线杂乱，干扰难免，此套方案抗干扰能力更好。

4. 开放的可编程控制器，可根据客户的实际要求，满足不同客户需要

5. 标准的总线通信，可增加编码器与控制器通信实现多个传感器的显示和控制

6. 这套方案采用CANOPEN总线通信，性价比高。调试简单

  实例分析1:

       某大型汽车生产制造商的起吊设备跨度大,动力线密布.同时还要求远端显示和行程控制。客户以前的解决方案是SSI编码器（国外 品牌）加显示仪表，实际应用中发现短距离还可以，但是如果大跨度就不准了。所以我公司向客户推荐了此套设备，得到客户的认可
