非屏蔽布线甚至可以减少通信错误。如果在LAN B端口上使用HUB会导致不同的问题，例如性能不佳，那么建议使用交换机而不是HUB。3BSE069463-600 Rev D 35操作面板中的以太网连接第7节附加安装提示一个好的解决方案可能是使用屏蔽以太网电缆，但仅在一端连接屏蔽。一种选择是打破屏蔽，见上图中的3。一种更优雅的方法是扩展屏蔽以太网电缆。使用EMC电缆密封套或常规塑料电缆密封套，移除外护套，并使用360°金属电缆夹将屏蔽件连接到安装板。2.将24 V DC和通信电缆放置在一个电缆干线/电缆管道中，将230/380 V AC放置在另一个电缆管道中。如果电缆需要交叉，仅以90°交叉。避免将电缆组合在一起，以获得更强的24Unshielded cabling may even result in fewer communication errors. If using a HUB on the LAN B port results in different issues, like bad performance, then it is recommended to use Switch instead of HUB. 3BSE069463-600 Rev D 35 Ethernet Connection in the Operator Panel Section 7 Additional Installation Tips A good solution may be to use a shielded Ethernet cable, but to connect the shield at one end only. One option is to break the shield, see 3 in drawing above. A more elegant method is to expand the shielded Ethernet cabling with. Use an EMC cable gland or regular plastic cable gland, remove the outer jacket and connect the shield to the installation plate with a 360° metal cable clamp. 2. Place the 24 V DC and communications cabling in one cable trunk/cable duct and 230/380 V AC in another. If the cables need to be crossed, cross them at 90° only. Avoid combining the cabling for stronger 24
