5X00121G01输入模块,5X00121G01说明书文档
模块化CPU基板（图3-4和3-5）电源模块必须插入这些基板的左侧插槽（未编号）。左侧插槽的尺寸和类型独特，仅支持电源模块。CPU模块（或特殊选项模块）必须安装在这些基板的插槽1中。插槽1是一种独特的尺寸和类型，仅支持CPU模块或特殊选项模块，如FIP远程输入/输出扫描仪（IC693BEM330）。插槽1标记为CPU/1。
5X00121G01输入模块编号为2及以上的插槽具有唯一的尺寸和类型，仅支持输入/输出或选项模块。支持扩展和远程基板，因此25针D型内螺纹扩展连接器位于基板的右端，用于连接扩展或远程基板。由于CPU是模块化的，如果需要其他功能，可以更换或更改为不同类型。每个系统只允许一个CPU基板。如果一个系统中使用了多个基板，则额外的基板必须是扩展型或远程型。默认情况下，模块化CPU基板的机架号始终为0。以太网接口模块（IC693CMM321）提供了一个接口，允许您连接90-30系列PLC通过外部收发器和AAUI电缆连接到以太网LAN，并连接到与网络上的主机和其他控制设备通信。Series 90-30 PLC的以太网接口具有客户端/服务器功能。作为客户，它可以启动与包含以太网接口的其他PLC的通信。这是从使用COMMREQ功能块的梯形图程序。作为服务器，它只响应请求来自其他设备，例如运行主机通信工具包应用程序的主机或另一个90-30系列PLC作为客户端。以太网接口允许您：直接将PLC连接到以太网启动从另一个设备到PLC的数据传输通过多达16个服务器连接同时与多个设备通信与其他GE Fanuc设备以及其他供应商的设备的接口从主机（或其他控制设备）进行通信使用诊断和站点管理工具诊断和维护您的系统以太网接口不支持Series 90-30/20/Micro手持式编程器。任何一个一个或两个以太网接口模块可以安装在任何Series 9030基板中。以太网接口通过启用的外部SQE连接到以太网收发器（GE Fanuc目录号IC649AEA102或IC649AEA103或同等产品。见附录J） 。下图显示了以太网接口的布局。
The Ethernet Interface module (IC693CMM321) provides an interface that allows you to attach the
Series 90-30 PLC to an Ethernet LAN via an external transceiver and AAUI cable, and to
communicate with hosts and other control devices on the network.
The Ethernet Interface for the Series 90-30 PLC has client/server capability. As a client it can
initiate communications with other PLCs containing Ethernet Interfaces. This is done from the
ladder program using the COMMREQ Function Block. As a server it responds only to requests
from other devices such as a Host computer running a Host Communications Toolkit application or
another Series 90-30 PLC acting as a client.
The Ethernet Interface allows you to:
Directly attach your PLC to an Ethernet network
Initiate transfer of data to the PLC from another device
Communicate simultaneously to multiple devices with up to 16 server connections
Interface with other GE Fanuc devices, as well as with devices from other vendors
Communicate from a Host computer (or other control device)
Diagnose and maintain your system using diagnostic and station management tools
The Ethernet Interface does not support the Series 90-30/20/Micro Hand-Held Programmer. Either
one or two Ethernet Interface modules can be installed in any Series 90-30 baseplate.
The Ethernet Interface connects to an Ethernet network through an external SQE enabled
transceiver (GE Fanuc catalog no. IC649AEA102 or IC649AEA103 or equivalent. See Appendix
J). The following figure shows the layout of the Ethernet Interface.
