10-20或图10-21。图10-21显示了标准（工厂制造）Y形电缆的制造方法。通过移除为早期版本的远程底板定制的Y形电缆中的引脚1，引脚7（0V）信号参考源于主（CPU）基板。在这些早期版本的远程底板中，引脚1连接到引脚7（0V），并且还AC耦合到远程机架接地。当将这些底板与100%屏蔽的Y形电缆结合使用时，引脚7（0V）参考将通过D超小型连接器外壳不正确地DC耦合到远程机架接地，该外壳DC耦合到远端机架接地。在远程底板IC693CHS393F（及更高版本）和IC693CHS 399E（及更低版本）中，引脚1屏蔽信号直流耦合到远程机架接地，而不连接到引脚7（0V）。这通过提供良好的连续电缆屏蔽实现了佳的抗干扰性，并且仍然允许引脚7（0V）信号参考源于CPU基板，而无需移除任何工厂或定制电缆中的引脚1。D超小型连接器外壳仍然与远程机架接地直流耦合。制作100%屏蔽电缆使用以下步骤制作100%屏蔽的电缆：1。剥去定制电缆上约5/8英寸的绝缘层，露出屏蔽层。2.从直接插入旧版本远程基板（IC693CHS393E、IC693CHS 399D或更早版本）的任何连接器上取下公引脚1。3.将开口环套圈置于电缆绝缘层上（图10-17）。4.在电缆绝缘层和套圈的顶部折叠屏蔽层。5.将金属罩的套环放在折叠护罩的顶部，并牢牢夹住罩。6.测试电缆在两个连接器外壳之间的导通性。在外壳之间连接欧姆表，并在两端弯曲电缆。如果金属化连接器罩未与电缆屏蔽罩的两端正确接触，则欧姆表上的连接将显示间歇性连续性。7.将金属带帽电缆插入远程底板扩展端口连接器或GE Fanuc WYE电缆，并牢固拧紧两个螺钉。安装和拧紧螺钉将使屏蔽与远程底板框架接地电气连接，远程底板框架应按照“安装”一章“底板安全接地”标题下的指示接地。“C C-8 Series 90-30 PLC I/O模块规格–2000年7月GFK-0898F接线图以下接线图显示了I/O扩展系统电缆的接线配置。提供了点对点电缆和Y形电缆的接线图。屏蔽加蔽线引脚25–引脚公25–引脚母金属化
10-20 or Figure 10-21. Figure 10-21 shows how the standard (factory made) Wye cables are made. By removing pin 1 in custom built Wye cables made for the earlier versions of remote baseplates, the pin 7 (0V) signal reference originates in the main (CPU) baseplate. In these earlier versions of the remote baseplates, pin 1 was tied to pin 7 (0V) and also AC coupled to the remote frame ground. When using these baseplates in combination with the 100% shielded Wye cables, the pin 7 (0V) reference would be improperly DC coupled to the remote frame ground through the D-subminiature connector shell, which is DC coupled to the remote frame ground. In the remote baseplates IC693CHS393F (and later) and IC693CHS399E (and later), the pin 1 shield signal is DC coupled to the remote frame ground and not attached to pin 7 (0V). This allows the best noise immunity by providing a good continuous cable shield, and still allows the pin 7 (0V) signal reference to originate in the CPU baseplate without the need for removing pin 1 in any factory or custom built cable. The D-subminiature connector shell is still DC coupled to the remote frame ground. Making a 100% Shielded Cable Use the following steps to build a 100% shielded cable: 1. Strip approximately 5/8 inch of insulation from your custom cable to expose the shield. 2. Remove the male Pin 1 from any connector plugging directly into an older version remote baseplate (IC693CHS393E, IC693CHS399D, or earlier). 3. Put split-ring ferrule over cable insulation (Figure 10-17). 4. Fold the shield back over top of the cable insulation and ferrule. 5. Place the collar of the metal hood over top of the folded shield and securely clamp the hood. 6. Test your cable for continuity between both connector shells. Connect an ohmmeter between the shells and flex the cable at both ends. If the metalized connector hood is not making proper contact with the cable shield at either end, the connection will show intermittent continuity on the ohmmeter. 7. Plug the metal hooded cable onto a remote baseplate expansion port connector or into a GE Fanuc WYE cable and securely tighten the two screws. Installing and tightening the screws will electrically connect the shield to the remote baseplate frame ground, which should in turn should be connected to earth ground as instructed in the “Installation” chapter, under the heading “Baseplate Safety Grounding.” C C-8 Series 90-30 PLC I/O Module Specifications – July 2000 GFK-0898F Wiring Diagrams The following wiring diagrams show the wiring configuration for I/O expansion system cables.
