3500/92 is a communication gateway module developed by Bently Nevada. The communication gateway module provides a wide range of serial (RS232/RS422/RS485) and Ethernet TCP/IP communication functions, used to integrate all rack monitoring values and status with process control and other automation systems. In addition, it also supports Ethernet communication with data collection software and 3500 rack configuration software. The supported protocols include: Modicon Modbus protocol (through serial communication), Modbus/TCP protocol (serial Modbus variant for TCP/IP Ethernet communication), and proprietary Bently Nevada protocol (for communication with 3500 rack configuration and data acquisition software packages). Update time: The data collection rate of all modules in the 3500 rack will not exceed 1 second, depending on the design of the rack.

Feature: For 10BASE-T star configuration Ethernet, the Ethernet connection is RJ45. In addition to the main value Modbus register, this component also supports communication interfaces, communication protocols, and additional functions. The main value Modbus register has been replaced by the configurable Modbus register utility, which can now provide the same functionality. Energy consumption: The typical power of the Modbus RS232/RS422 I/O module is 5.0 watts, and the typical power of the Modbus RS485 I/O module is 5.6 watts. Data type: Using high-speed internal networks to collect information from other modules in the rack, including current measured values with time stamps, module status, and current alarm status. The exact data type returned depends on the channel configuration and module type.

PLC控制器本身的硬件采用积木式结构，各厂家产品结构大同小异。以日本欧姆龙C200HE为例，为总线模板框式结构，基本框架(CPU母板)上装有CPU模板，其它槽位装有I/O模板;如果I/O模板多时，可由CPU母板经I/O扩展电缆连接I/O扩展母板，在其上装I/O模板;另一种方法是配备远程I/O从站等。这些都说明了PLC厂家将硬件各部件均向用户开发，便于用户选用，配置成规模不等的PLC，而且这种硬件配置的开放性，为制造商、分销商(代理商)、系统集成商、最终用户带来很多方便，为营销供应链带来很大便利，这是一大成功经验。
