　　產(chǎn)品類型 總線接收器模塊

　　IC697BEM711是用于實現(xiàn)機架擴展的總線接口模塊 (BEM)。具體來說，該模塊是一個總線接收器模塊。使用此模塊可以安裝額外的 I/O 和專用模塊，并允許安裝多達七 (7) 個擴展機架。該模塊具有兩 (2) 個通信接口，端口 1 用作擴展端口，用于建立與 CPU 或其他 BEM 711 和 BEM 713 的連接。另一個通信接口用作擴展端口輸出，用于連接擴展機架或其他 BEM 711 模塊。每個 BEM 711 或 BEM 713 之間的允許距離為 50 英尺或 15 米。IC697BEM711不僅限于機架擴展。由于傳入和傳出通信電纜的數(shù)據(jù)是表示擴展機架可用數(shù)據(jù)的低電平信號，因此還可以實現(xiàn)系統(tǒng)故障隔離。故障排除和維護也得到了簡化，因為擴展機架可以隔離以進行故障排除。此外，還可以實現(xiàn)輸出保持，使故障或機架維護中的輸出模塊能夠保持單個最后狀態(tài)。該模塊還提供三 (3) 個統(tǒng)計信息 LED 指示燈，用于指示機架正常、上一個機架和總線活動。該模塊完全使用 MS-DOS 或 Windows 編程軟件包進行配置。最后一個擴展機架必須安裝目錄號為 IC697ACC702 的終端電阻器。此組件對于發(fā)出網(wǎng)絡結(jié)束信號和識別擴展配置的最后一個節(jié)點是必需的。該模塊支持 500 KB/s 的傳輸速率和 800 mA 的背板電流消耗。

　　IC697BEM711模塊是總線接收模塊。IC697BEM711模塊的功能包括高速并行總線擴展接口、支持 7 個擴展機架、系統(tǒng)故障隔離、簡單的軟件配置以及支持保持機器的最后狀態(tài)。模塊上的三個 LED 指示燈提供模塊的狀態(tài)以及總線擴展端口狀態(tài)和擴展狀態(tài)。通過使用 IC697BEM711 模塊，總共可以使用 15 米的電纜擴展到最多 7 個額外的 IC697 PLC 機架。IC697BEM711模塊占用PLC機箱中的一個插槽。模塊的前面板上提供了兩個連接器：一個連接器用于連接上游或 CPU 機架，另一個連接器用于通過菊花鏈布置連接到其他擴展機架。

　　Product Description Bus Extension Module (BEM)

　　Manufacturer GE Fanuc/Emerson Automation

　　Slot width single slot

　　Series 90-70 series

　　Part number IC697BEM711

　　Installation Position 90-70 series CPU mainboard

　　Part number IC697BEM711

　　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.
