屏蔽处理所有GE Fanuc工厂制造的电缆均采用连续或100%屏蔽。这表示编织电缆屏蔽层连接至连接器的金属外壳围绕连接器的整个周长。这为机架接地，用于连接到电缆屏蔽上的任何噪声能量。对于按图10-18制作的定制长度电缆，可实现最佳抗噪性当使用与电缆的编织和箔屏蔽和连接器外壳在终端上。仅将排流线焊接到连接器外壳是不够的。
HONEYWELL 51403427-175模块它要求电缆屏蔽层在整个长度上连续电缆，包括终端。下图显示了之前折叠编织屏蔽的推荐方法将电缆插入金属盖。对于典型的工业应用，所有扩展和远程基板电缆都可以由塑料外壳盖制成，并应按图10-19所示接线。在任何一个在这种情况下，针脚1应连接到自定义长度电缆和应遵循以下所列的建议，对电缆中的Y形电缆进行处理远程（IC693CHS392/399）基板。当使用100%屏蔽电缆时，系统中的所有本地（CPU和扩展）基板必须牢固地参照同一接地点或两个接地点之间的电位差
基板可能会干扰信号传输。
Shield Treatment
All GE Fanuc factory made cables are made with a continuous, or 100% shield. This
means that the braided cable shield is connected to the metal shell of the connector
around the entire perimeter of the connector. This provides a low impedance path to
frame ground for any noise energy that is coupled onto the cable shield.
For custom length cables made per Figure 10-18, the best noise immunity is achieved
when using a metalized connector cover that makes contact with the cable’s braided and
foil shielding and with the connector shell on the terminating end.
Note
It is not sufficient to only solder the drain wire to the connector shell. It
is required that the cable’s shield be continuous across the entire length
of the cable, including at the terminations. The figure below shows the
recommended method for folding the braided shield back before
inserting the cable into a metallized cover.For typical industrial applications, all expansion and remote baseplate cables can be
made with plastic shell covers and should be wired as shown in Figure 10-19. In either
case, pin 1 should be wired into both ends of the custom length cable and the
recommendations listed below should be followed for the Wye cables treatment in the
remote (IC693CHS392/399) baseplates.
When using 100% shielded cables all local (CPU and expansion) baseplates in the system
must be solidly referenced to the same ground point or a potential difference between
baseplates could disturb signal transmission.
