IC693BEM331是一款总线控制器模块。它是通用席瑞斯90-30可编程逻辑控制器（PLC）产品系列的一部分。
该模块的主要功能是将90-30系列PLC连接到专有的Genius I/O总线，从而允许PLC与Genius模块进行通信，这些模块可能包括离散、模拟和特殊用途的现场设备。它还能够支持远程I/O分支的通信，包括通过远程I/O扫描仪模块连接的90-70系列I/O机架，以及通过总线接口单元的现场控制I/O站。
IC693BEM331模块配备了多种状态LED，如正常（OK）LED和通信（COM）LED。正常LED的稳定亮起表示模块正常运行，而COM LED的稳定亮起则表示总线控制器模块处于主动通信状态。如果COM LED闪烁，这可能表示存在总线连接间歇或错误。
该模块能够处理总线上来自现场设备的最多128字节的输入和输出数据。
The IC693BEM331 is a bus controller module. It is part of the general Cerise 90-30 Programmable Logic Controller (PLC) product family.
The main function of the module is to connect the 90-30 series PLCS to the proprietary Genius I/O bus, allowing the PLCS to communicate with Genius modules, which may include discrete, analog, and special-purpose field devices. It is also capable of supporting communication of remote I/O branches, including the 90-70 series I/O racks connected via the remote I/O scanner module, as well as field control I/O stations via the bus interface unit.
The IC693BEM331 module is equipped with multiple state leds, such as Normal (OK) leds and Communication (COM) leds. The steady light of the normal LED indicates that the module is operating normally, while the steady light of the COM LED indicates that the bus controller module is in the active communication state. If the COM LED blinks, it may indicate a bus connection pause or an error.
The module is capable of processing up to 128 bytes of input and output data from field devices on the bus.
