零件编号 IC697BEM711
产品类型 总线接收器模块
IC697BEM711是用于实现机架扩展的总线接口模块 (BEM)。具体来说，该模块是一个总线接收器模块。使用此模块可以安装额外的 I/O 和专用模块，并允许安装多达七 (7) 个扩展机架。该模块具有两 (2) 个通信接口，端口 1 用作扩展端口，用于建立与 CPU 或其他 BEM 711 和 BEM 713 的连接。另一个通信接口用作扩展端口输出，用于连接扩展机架或其他 BEM 711 模块。每个 BEM 711 或 BEM 713 之间的允许距离为 50 英尺或 15 米。IC697BEM711不仅限于机架扩展。由于传入和传出通信电缆的数据是表示扩展机架可用数据的低电平信号，因此还可以实现系统故障隔离。故障排除和维护也得到了简化，因为扩展机架可以隔离以进行故障排除。此外，还可以实现输出保持，使故障或机架维护中的输出模块能够保持单个最后状态。该模块还提供三 (3) 个统计信息 LED 指示灯，用于指示机架正常、上一个机架和总线活动。该模块完全使用 MS-DOS 或 Windows 编程软件包进行配置。最后一个扩展机架必须安装目录号为 IC697ACC702 的终端电阻器。此组件对于发出网络结束信号和识别扩展配置的最后一个节点是必需的。该模块支持 500 KB/s 的传输速率和 800 mA 的背板电流消耗。
IC697BEM711模块是总线接收模块。IC697BEM711模块的功能包括高速并行总线扩展接口、支持 7 个扩展机架、系统故障隔离、简单的软件配置以及支持保持机器的最后状态。模块上的三个 LED 指示灯提供模块的状态以及总线扩展端口状态和扩展状态。通过使用 IC697BEM711 模块，总共可以使用 15 米的电缆扩展到最多 7 个额外的 IC697 PLC 机架。IC697BEM711模块占用PLC机箱中的一个插槽。模块的前面板上提供了两个连接器：一个连接器用于连接上游或 CPU 机架，另一个连接器用于通过菊花链布置连接到其他扩展机架。

Product Type Bus receiver module
The IC697BEM711 is a Bus interface module (BEM) for rack extension. Specifically, the module is a bus receiver module. Using this module, additional I/O and dedicated modules can be installed and up to seven (7) extension racks can be installed. The module has two (2) communication interfaces, with port 1 used as an expansion port for establishing connections to the CPU or other BEM 711 and BEM 713. The other communication interface is used as an expansion port output to connect to the expansion rack or other BEM 711 modules. The permissible distance between each BEM 711 or BEM 713 is 50 feet or 15 meters. The IC697BEM711 is not limited to rack expansion. Since the data from the incoming and outgoing communication cables are low-level signals representing the data available to the extension rack, system fault isolation is also possible. Troubleshooting and maintenance is also simplified because the extension rack can be isolated for troubleshooting. In addition, output hold can be implemented so that the output module in failure or rack maintenance can maintain a single final state. The module also provides three (3) statistical LED indicators to indicate rack health, previous rack, and bus activity. The module is configured entirely using MS-DOS or Windows programming packages. The last extension rack must be equipped with a terminal resistor with directory number IC697ACC702. This component is necessary to signal the end of the network and to identify the last node of the extended configuration. The module supports a transfer rate of 500 KB/s and a backplane current consumption of 800 mA.
The IC697BEM711 module is a bus receiving module. Features of the IC697BEM711 module include a high-speed parallel bus expansion interface, support for seven expansion racks, system fault isolation, simple software configuration, and support for maintaining the last state of the machine. Three LED indicators on the module provide the status of the module as well as the status of the bus expansion port and expansion status. By using the IC697BEM711 module, a total of 15 meters of cable can be extended to up to seven additional IC697 PLC racks. The IC697BEM711 module occupies a slot in the PLC chassis. Two connectors are provided on the front panel of the module: one connector for connecting upstream or CPU racks, and the other connector for connecting to other expansion racks via a Daisy chain arrangement.
