PM_CL_IDX

  struct PM_CL_IDX

  {
    SRVD sd;
    int  Axis;
    long IndexPos;
  };

This structure is used with the CL_IDX_SVC RPC call to read the Index Register of an LM628 axis controller on a ZY. This register records the value that the Position Register held at the Index Pulse location, when the last CL_FHM_SVC call was executed for this axis.

sd.TID

Axis

The axis number of the LM628 controller. The `Azimuth' axis is axis 0, and the `Elevation' axis is axis 1.
