在808D 自定义画面脚本中 ，如何简单编写脚本读写工件坐标系G54....G59零点偏移量值？在西门子技术文档中给出的“NCK/Channel/UserFrame/linshift[n]",n为总轴数加1，该地址在自定义画面中不能直接用于读取G54的偏移量？

<let name="ax_name"type="string"/>
<let name="num_mach_axis"/>
<let name="axis_index_in_channel" />
<let name="frame_type"/>
<let name="zero_offset"/>

<form name="Main">

 <op>axis_index_in_channel = 0</op>
 
  <!--frame_type

400回复的一份自定义画面读写G54坐标偏置的脚本！可以直接在自定义画面中，直接读写零偏。

谢谢各位大神的回复！！！
