NI SCXI-1327模块卡件
1.产 品 详 情 资 料：
底板仅包含无源元件。它包含用于CEX总线的输入和输出连接器、用于CI862单元的插槽、用于Genius总线手持式监视器的端口、用于模块冗余链路通信的高速串行端口和用于TRIO现场总线连接的端口。CI862包含带闪存、RAM、LED指示灯、电源的Coldfire MCF5307微控制器，和带有双端口存储器的CEX总线接口，桥接到GE/FanucµGenie通信模块。µGenie处理CI862载波模块和TRIO现场总线之间的所有数据传输，使载波CPU能够控制远程I/O。指示灯R（un）、F（ault）、通信错误、主（总线主）和双（冗余）总线类型菊花链总线电缆的LED指示灯；单双绞线加屏蔽或双绞线。协议类似于RS422标准通信速度153.6 ext，38.4，76.8，153.6 std kbit/s总线容量（一段）最多32个设备。16个设备，38.4 Kbaud。包括CI862和手持式显示器。电气总线电缆两端的总线终端75、100、120或150欧姆电阻器。最大总线长度38.4 Kbaud时为7500英尺，76.8 Kbaud下为4500英尺，153.6 Kbaud延伸时为3500英尺，153.6Kbaud扩展时为2000英尺，标准。每个波特率下的最大长度也取决于电缆类型。电流隔离是状态指示灯红色LED指示错误绿色LED指示运行
The baseplate contains only passive elements. It holds the input and output connectors for the CEX-Bus, a slot for the CI862 unit, a port used for the Genius Bus Hand Held Monitor, a high speed serial port used for module redundancy link communications and a port for the TRIO Field Bus connection.CI862 contains the Coldfire MCF5307 Microcontroller with Flash memory, RAM, LED indicators, power supply, and CEX-Bus interface with dual port memory, bridged to a GE/Fanuc µGenie Communication Module. The µGenie handles all data transfer between the CI862 Carrier module and the TRIO FIELD BUS, allowing the Carrier CPU to control the remote I/O. Indicators LED indicators for R(un), F(ault), Communication Error, Primary (Bus Master), and Dual (redundancy) Bus Type Daisy-chained bus cable; single twisted pair plus shield or Twinax. Protocol similar to the RS422 standard Communication speed 153.6 ext, 38.4, 76.8, 153.6 std kbit/s Bus Capacity (one segment) Max 32 devices. 16 devices at 38.4 Kbaud. Includes CI862 and Hand-held Monitor. Bus Termination 75, 100, 120, or 150 ohm resistor at both ends of electrical bus cable. Maximum Bus Length 7500 feet at 38.4 Kbaud, 4500 feet at 76.8 Kbaud, 3500 feet at 153.6 Kbaud extended, 2000 feet at 153.6 Kbaud, standard. Maximum length at each baud rate also depends on cable type. Galvanic Isolation Yes Status Indicators Red LED for error Green LED for run
