CI873A 交流800M通信接口

CI873A是交流800M通信接口，通过以太网/IP协议与外部以太网设备连接。TP867底板有两个RJ45以太网连接器，只使用支持100Mbps的CH1连接器。CI873扩展单元包含CEX-Bus逻辑、通信单元和DC/DC转换器，该转换器通过CEX-Bus从+24 V电源提供所需电压。新的S200CI873IoHwlib增加了对与CI873A一起使用的S200 I/O适配器200-AENTR的支持。

这种新的适配器为在satcon 200、satline 200、高级控制器210、高级控制器250和AC 800C上直接连接S200 I/O提供了一个简单而经济的升级路径。200-AENTR有两个以太网端口和一个内置交换机，这意味着适配器可以使用交叉的以太网电缆连接到CI873，而不需要外部交换机。

CI873A模块只适用于System 800xA 6.0.3.3、6.1.1及后续版本。CI873A支持来自5.1 FP4的6对冗余CI873A。

CI873A 交流800M通信接口

The CI873A is an AC 800M communication interface that connects to external Ethernet devices using the EtherNet/IP protocol. The TP867 Baseplate has two RJ45 Ethernet connectors, but only the CH1 connector that supports 100Mbps is used. The CI873 expansion unit contains the CEX-Bus logic, a communication unit, and a DC/DC converter that supplies the required voltage from +24 V supply through the CEX-Bus. The new S200CI873IoHwlib adds support for the S200 I/O adaptor 200-AENTR to be used with CI873A.

This new adaptor gives a simple and cost-effective upgrade path for directly connected S200 I/O on SattCon 200, SattLine 200, Advant Controller 210, Advant Controller 250, and AC 800C. The 200-AENTR has two Ethernet ports with an in-built switch, which means that the adaptors can be daisy-chained to the CI873 using cross-wired Ethernet cables without the need for external switches.

The CI873A module will only work with System 800xA 6.0.3.3, 6.1.1 and subsequent versions. The CI873A support 6 redundant pairs of CI873A from 5.1 FP4.
