GE IC693DNM200  设备网络主模块

IC693DNM200 是一款设备网络主模块。该模块是一个单插槽通信模块，是 90-30 系列可编程逻辑控制器 （PLC） 平台的一部分，该平台以前由 GE Fanuc 制造，现在由艾默生自动化制造。该模块配有单个DeviceNet终端。它还具有一 （1） 个 RS232 9 针 D 壳母端口，用作模块服务端口。

IC693DNM200支持DeviceNet协议的所有数据速率，特别是125K，250K和500K传输速率。每个从设备的主设备最多可传输 255 字节的输入数据和 255 字节的输出数据，最多可以将 3972 字节的输入数据和 3972 字节的输出数据传输到该主模块。此外，使用此模块总共可以建立 126 个 I/O 连接，因为它能够通信多达 63 个从设备，其中每个从设备最多可分配两 （2） 个 I/O 站。该模块支持和可配置的数据连接是轮询、选通、循环或 COS。 此 DeviceNet 主模块还支持显式消息传递、未连接消息管理器 （UCMM） 和每个从站单元一 （1） 个代理连接。

此外，该模块可以在双模式下运行，同时作为主站和从站。可以配置专门在通信丢失期间的故障行为，以便在发生上述错误时提供可接受的系统反应。该模块还带有可升级的固件，允许通过RS232服务端口下载模块更新和错误修复。

IC693DNM200 is a device network main module. This module is a single slot communication module, which is part of the 90-30 series Programmable logic controller (PLC) platform, which was previously manufactured by GE Fanuc and is now manufactured by Emerson Automation. This module is equipped with a single DeviceNet terminal. It also has one (1) RS232 9-pin D-shell female port used as a module service port.

IC693DNM200 supports all data rates of the DeviceNet protocol, especially the transmission rates of 125K, 250K, and 500K. Each slave device's main device can transmit up to 255 bytes of input data and 255 bytes of output data, and can transmit up to 3972 bytes of input data and 3972 bytes of output data to the main module. In addition, a total of 126 I/O connections can be established using this module, as it can communicate with up to 63 slave devices, with each slave device being able to allocate up to two (2) I/O stations. The module supports and can configure data connections such as polling, gating, looping, or COS. This DeviceNet main module also supports explicit messaging, unconnected message managers (UCMM), and one (1) proxy connection per slave unit.

In addition, the module can operate in dual mode and act as both the master and slave stations. Fault behavior can be configured specifically during communication loss to provide acceptable system response in the event of the aforementioned error. This module also comes with upgradable firmware, allowing module updates and error fixes to be downloaded through the RS232 service port.
