5X00121G01輸入模塊,5X00121G01說明書文檔
模塊化CPU基板（圖3-4和3-5）電源模塊必須插入這些基板的左側插槽（未編號）。左側插槽的尺寸和類型獨特，僅支持電源模塊。CPU模塊（或特殊選項模塊）必須安裝在這些基板的插槽1中。插槽1是一種獨特的尺寸和類型，僅支持CPU模塊或特殊選項模塊，如FIP遠程輸入/輸出掃描儀（IC693BEM330）。插槽1標記為CPU/1。
5X00121G01輸入模塊編號為2及以上的插槽具有唯一的尺寸和類型，僅支持輸入/輸出或選項模塊。支持擴展和遠程基板，因此25針D型內螺紋擴展連接器位于基板的右端，用于連接擴展或遠程基板。由于CPU是模塊化的，如果需要其他功能，可以更換或更改為不同類型。每個系統只允許一個CPU基板。如果一個系統中使用了多個基板，則額外的基板必須是擴展型或遠程型。默認情況下，模塊化CPU基板的機架號始終為0。以太網接口模塊（IC693CMM321）提供了一個接口，允許您連接90-30系列PLC通過外部收發器和AAUI電纜連接到以太網LAN，并連接到與網絡上的主機和其他控制設備通信。Series 90-30 PLC的以太網接口具有客戶端/服務器功能。作為客戶，它可以啟動與包含以太網接口的其他PLC的通信。這是從使用COMMREQ功能塊的梯形圖程序。作為服務器，它只響應請求來自其他設備，例如運行主機通信工具包應用程序的主機或另一個90-30系列PLC作為客戶端。以太網接口允許您：?直接將PLC連接到以太網?啟動從另一個設備到PLC的數據傳輸?通過多達16個服務器連接同時與多個設備通信?與其他GE Fanuc設備以及其他供應商的設備的接口?從主機（或其他控制設備）進行通信?使用診斷和站點管理工具診斷和維護您的系統以太網接口不支持Series 90-30/20/Micro手持式編程器。任何一個一個或兩個以太網接口模塊可以安裝在任何Series 9030基板中。以太網接口通過啟用的外部SQE連接到以太網收發器（GE Fanuc目錄號IC649AEA102或IC649AEA103或同等產品。見附錄J） 。下圖顯示了以太網接口的布局。
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.
