I/OIMAGE仪器电缆数据对诊断功能的开发应用

Development and application of diagnosis function of cable data pairs in I/O IMAGE instrument

本文从电缆的构造和仪器外设的带载能力着手,分析了I/O IMAGE仪器数据对诊断功能的工作原理和使用方法,并结合野外生产讲述了利用数据对诊断功能排除外线故障的方法及使用实例。

Starting from the structure of cable and the load capacity of external devices, the paper analyzed the work principle and operation method of diagnosis function of data pairs in I/O IMAGE instrument and talked about how to use the diagnosis function of data pairs to remove the failure of cable and showed some cases in combination with field production.
