IC693CMM311是90-30系列PLC平台的通信协处理器模块。该系列PLC特别是IC693CMM311以前由GE Fanuc制造，但最近被艾默生自动化收购。该模块提供CCM、远程终端单元(RTU)和SNP连接到托管该模块的任何控制器。具体来说，IC693CMM311与模块化系列90-30 CPU兼容使用。IC693CMM311带有两(2)个通信接口，如支持RS232标准的端口1和支持RS232 / RS422和RS485电气标准的端口2。每个端口都是一个25针D-shell接口。该模块配有重启通信按钮，无需重启整个模块即可重启通信。

IC693CMM311端口可配置为多种协议组合，例如两个端口上的CCM协议；CCM协议在端口1，RTU协议在端口2；端口1上的RTU协议，端口2上的CCM协议；两个端口上的RTU协议；两个端口上的SNP和SNP-X协议；端口1上的SNP和SNP-X协议，端口2上的CCM协议；端口1上的CCM协议，端口2上的SNP和SNP-X协议；SNP和SNP-X协议在端口1，RTU协议在端口2；端口1的RTU协议，端口2的SNP和SNP-X协议。CCM、SNP和RTU支持的传输速度为300、600、1200、240、4800、9600和19200波特率。兼容的预组装电缆是目录号为IC693CBL305的星形连接电缆。该模块带有模块正常、端口1和端口2状态LED指示灯，用于确定模块的操作状态。

IC693CMM311模块是GE Fanuc 90-30系列的一部分，作为CCM或通信协处理器模块。它被设计成高性能设备。GE Fanuc系列90-30 IC693CMM311通信协处理器模块与GE系列90-30产品线中的所有模块化CPU兼容，但不能用于任何嵌入式GE系列90-30 CPU，如311、313或323嵌入式GE CPUs。任何带有模块化CPU的GE Fanuc系列90-30 PLC都将受益于GE IC693CMM311通信协处理器模块的安装及其所有特性和功能。该通信协处理器模块可支持的协议有SNP协议、Modbus或RTU从通信协议以及GE Fanuc CCM通信协议。

GE Fanuc系列90-30 IC693CMM311通信协处理器模块有2个内置串行端口，称为端口1和端口2。端口1支持的应用程序是RS-232应用程序，端口2支持的应用程序是RS-232应用程序和RS-485应用程序。这两个端口都有线连接到IC693CMM311通信协处理器模块的唯一连接器，这可能使模块布线困难，但该模块附带阿格Wye电缆，称为IC693CBL305 Wye电缆，技术人员可以使用它来分隔两个端口，使模块布线更容易。该模块可通过默认设置或组态软件进行配置。某些CPU(型号331和更高型号)在其CPU基板上一次可以支持多达4个这样的通信协处理器模块。

IC693CMM311

IC693CMM311 is a communication coprocessor module for the 90-30 series PLC platform. This series of PLCs, especially IC693CMM311, was previously manufactured by GE Fanuc but recently acquired by Emerson Automation. This module provides CCM, Remote Terminal Unit (RTU), and SNP connections to any controller hosting the module. Specifically, IC693CMM311 is compatible with modular series 90-30 CPUs. IC693CMM311 comes with two (2) communication interfaces, such as port 1 that supports RS232 standard and port 2 that supports RS232/RS422 and RS485 electrical standards. Each port is a 25 pin D-shell interface. This module is equipped with a restart communication button, which allows communication to be restarted without the need to restart the entire module. The IC693CMM311 port can be configured with multiple protocol combinations, such as the CCM protocol on two ports; The CCM protocol is on port 1, and the RTU protocol is on port 2; RTU protocol on port 1, CCM protocol on port 2; RTU protocol on two ports; SNP and SNP-X protocols on two ports; The SNP and SNP-X protocols on port 1, and the CCM protocol on port 2; CCM protocol on port 1, SNP and SNP-X protocols on port 2; The SNP and SNP-X protocols are on port 1, and the RTU protocol is on port 2; The RTU protocol for port 1, the SNP and SNP-X protocols for port 2. CCM, SNP, and RTU support transmission speeds of 300, 600, 1200, 240, 4800, 9600, and 19200 baud rates. The compatible pre assembled cable is a star connection cable with catalog number IC693CBL305. This module comes with module normal, port 1, and port 2 status LED indicators to determine the operational status of the module. The IC693CMM311 module is part of the GE Fanuc 90-30 series and serves as a CCM or communication coprocessor module. It is designed as a high-performance device. The GE Fanuc series 90-30 IC693CMM311 communication coprocessor module is compatible with all modular CPUs in the GE series 90-30 product line, but cannot be used with any embedded GE series 90-30 CPUs, such as 311, 313, or 323 embedded GE CPUs. Any GE Fanuc series 90-30 PLC with a modular CPU will benefit from the installation of the GE IC693CMM311 communication coprocessor module and all its features and functions. The communication coprocessor module can support protocols such as SNP protocol, Modbus or RTU slave communication protocol, and GE Fanuc CCM communication protocol.
