產(chǎn)品類型 總線接收器模塊
IC697BEM711是用于實(shí)現(xiàn)機(jī)架擴(kuò)展的總線接口模塊 (BEM)。具體來說，該模塊是一個(gè)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(dá)七 (7) 個(gè)擴(kuò)展機(jī)架。該模塊具有兩 (2) 個(gè)通信接口，端口 1 用作擴(kuò)展端口，用于建立與 CPU 或其他 BEM 711 和 BEM 713 的連接。另一個(gè)通信接口用作擴(kuò)展端口輸出，用于連接擴(kuò)展機(jī)架或其他 BEM 711 模塊。每個(gè) 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(jī)架擴(kuò)展。由于傳入和傳出通信電纜的數(shù)據(jù)是表示擴(kuò)展機(jī)架可用數(shù)據(jù)的低電平信號，因此還可以實(shí)現(xiàn)系統(tǒng)故障隔離。故障排除和維護(hù)也得到了簡化，因?yàn)閿U(kuò)展機(jī)架可以隔離以進(jìn)行故障排除。此外，還可以實(shí)現(xiàn)輸出保持，使故障或機(jī)架維護(hù)中的輸出模塊能夠保持單個(gè)最后狀態(tài)。該模塊還提供三 (3) 個(gè)統(tǒng)計(jì)信息 LED 指示燈，用于指示機(jī)架正常、上一個(gè)機(jī)架和總線活動(dòng)。該模塊完全使用 MS-DOS 或 Windows 編程軟件包進(jìn)行配置。最后一個(gè)擴(kuò)展機(jī)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(luò)結(jié)束信號和識別擴(kuò)展配置的最后一個(gè)節(jié)點(diǎn)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(kuò)展接口、支持 7 個(gè)擴(kuò)展機(jī)架、系統(tǒng)故障隔離、簡單的軟件配置以及支持保持機(jī)器的最后狀態(tài)。模塊上的三個(gè) LED 指示燈提供模塊的狀態(tài)以及總線擴(kuò)展端口狀態(tài)和擴(kuò)展?fàn)顟B(tài)。通過使用 IC697BEM711 模塊，總共可以使用 15 米的電纜擴(kuò)展到最多 7 個(gè)額外的 IC697 PLC 機(jī)架。IC697BEM711模塊占用PLC機(jī)箱中的一個(gè)插槽。模塊的前面板上提供了兩個(gè)連接器：一個(gè)連接器用于連接上游或 CPU 機(jī)架，另一個(gè)連接器用于通過菊花鏈布置連接到其他擴(kuò)展機(jī)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.
