IC693CMM302是一款Genius通信模块，属于艾默生自动化的90-30系列可编程逻辑控制器(PLC ),以前由GE Fanuc automation生产。该模块是单插槽宽度模块，提供Genius协议连接，每个控制器最多可与31个设备和62个设备通信，因为90-30系列系统允许每个控制器最多配置两(2)个IC693CMM302。IC693CMM302允许每个IC693CMM302发送128字节和接收128字节的全局数据，并支持PLC寄存器，如全局寄存器(%G)、离散输入(%I)、离散输出(%Q)、模拟输入(%AI)、模拟输出(%AQ)和寄存器存储器(%R)。它支持基于软件的诊断，如状态位、向90-70系列PLC报告故障。该模块的环境等级包括0摄氏度至+60摄氏度(+32华氏度至+140华氏度)的工作温度；储存温度为–25摄氏度至+70摄氏度(–13华氏度至+158华氏度)；湿度为5%至95%(非冷凝)，而机械额定值包括0.2英寸位移5Hz至10Hz和1 G 10Hz至200Hz工作振动和5 G 10Ms持续时间的工作冲击。除了全局数据交换，IC693CMM302还允许通过个人或工业计算机进行数据监控，使用I/O模块监控数据，通过Genius总线进行设备通信，以及I/O仿真。IC693CMM302在5v直流电压下的背板功耗为%3C300 mA。除了90-30系列PLC之外，它还可以与90-70系列、6系列PLC以及Genius手持监视器(HHM)一起用于本地配置。

90-30系列IC693CMM302通信模块是由GE Fanuc设计和制造的GCM+设备，也称为增强型Genius通信模块。IC693CMM302增强型Genius通信模块可以在多达32台设备之间进行全球数据通信。这些设备是连接到genius总线的阿格系列90-30 PLC和31个其他设备。建议将IC693CMM302增强型Genius通信模块安装在主机PLC系统的CPU底板上，以实现最高效的操作，但也可以安装在同一系统的远程底板或扩展底板上。但是，增强型Genius通信模块不能安装在装有常规Genius通信模块或GCM的PLC中。

多个增强型genius通信模块(如IC693CMM302模块)可以安装在单个PLC系统中，每个增强型Genius通信模块都有自己的Genius总线，这意味着每个模块可以同时连接到多达31个附加设备并与之通信。例如，带有2个增强型Genius通信模块的90-30 GE系列PLC可以同时与多达62个附加设备进行通信。IC693CMM302增强型Genius通信模块主要用于交换全局数据，但它也可以处理工业或个人计算机的数据监控、总线设备之间的点对点通信和主从通信，以及来自genius I/O模块的数据监控(注意，通信模块不能控制这些I/O模块。)

IC693CMM302L

IC693CMM302 is a Genius communication module belonging to Emerson Automation’s 90-30 series programmable logic controllers (PLCs), previously produced by GE Fanuc Automation. This module is a single slot width module that provides Genius protocol connectivity. Each controller can communicate with up to 31 devices and 62 devices, as the 90-30 series system allows for a maximum of two (2) IC693CMM302 configurations per controller. IC693CMM302 allows each IC693CMM302 to send and receive 128 bytes of global data, and supports PLC registers such as global registers (% G), discrete inputs (% I), discrete outputs (% Q), analog inputs (% AI), analog outputs (% AQ), and register memory (% R). It supports software based diagnosis, such as status bits, reporting faults to the 90-70 series PLC. The environmental level of this module includes operating temperatures ranging from 0 ° C to+60 ° C (+32 ° F to+140 ° F); The storage temperature is -25 ° C to+70 ° C (-13 ° F to+158 ° F); The humidity ranges from 5% to 95% (non condensing), while the mechanical rating includes 0.2 inch displacement of 5Hz to 10Hz and 1 G 10Hz to 200Hz working vibration and 5 G 10Ms duration of working shock. In addition to global data exchange, IC693CMM302 also allows data monitoring through personal or industrial computers, monitoring data using I/O modules, device communication through Genius bus, and I/O simulation. The backplane power consumption of IC693CMM302 at 5V DC voltage is% 3C300 mA. In addition to the 90-30 series PLC, it can also be used for local configuration with the 90-70 series, 6 series PLC, and Genius handheld monitor (HHM).
The 90-30 series IC693CMM302 communication module is a GCM+device designed and manufactured by GE Fanuc, also known as an enhanced Genius communication module. The IC693CMM302 enhanced Genius communication module can enable global data communication between up to 32 devices. These devices are connected to the Genius bus of the Ager series 90-30 PLC and 31 other devices. It is recommended to install the IC693CMM302 enhanced Genius communication module on the CPU motherboard of the host PLC system for the most efficient operation, but it can also be installed on the remote motherboard or expansion motherboard of the same system. However, enhanced Genius communication modules cannot be installed in PLCs equipped with conventional Genius communication modules or GCMs.
Multiple enhanced Genius communication modules (such as the IC693CMM302 module) can be installed in a single PLC system, with each enhanced Genius communication module having its own Genius bus, which means that each module can simultaneously connect to and communicate with up to 31 additional devices. For example, a 90-30 GE series PLC with two enhanced Genius communication modules can communicate with up to 62 additional devices simultaneously. The IC693CMM302 enhanced Genius communication module is mainly used for exchanging global data, but it can also handle data monitoring of industrial or personal computers, point-to-point communication and master-slave communication between bus devices, and data monitoring from Genius I/O modules (note that communication modules cannot control these I/O modules)
