产品详情资料
ASI模块通过连接到I/O扩展器总线的共享内存接口与控制器通信。ASI模块用输入的当前值不断更新共享内存设备(双端口RAM)。控制器可以随时读取这些值,即使ASI模块同时写入双端口RAM。
ASI模块为I/O扩展总线接口使用自定义门阵列。集成电路包含所有控制逻辑和通信协议。该集成电路提供以下功能:•地址比较和检测消息解码和翻译总线信号的数据线滤波。
车载巴士司机扩展器总线监视器。双端口RAM存储控制器和I/O模块微控制器可同时访问的数据。所有输入的数据值,通道值根据工厂校准进行调整。热电偶输入接收冷接点参考补偿。必要时进行引线电阻调整(仅供冷接点参考)。ASI模块通过I/Oexpander总线向控制器提供值。这些值以工程单位表示。
ASI模块向控制器发送每个输入通道的状态指示。此状态表示ASI模块检测到的任何硬件错误和信道配置错误。
终端单元IMASI23模块使用一个NTAI06终端单元连接现场信号。NKAS01或KAS11电缆通过P3连接器将终端装置连接至ASI模块。
终端单元包含用于冷连接的RTD
热电偶输入的补偿。它们还包含将4至20毫安磁场信号转换为1至5 VDC所需的电路,该电压输入至模拟输入2-6 WBPEEUI240774A0
自动调整和校正模块。The ASI module communicates with the controller through ashared memory interface connected to the I/O expanderbus.The ASI module constantly updates the shared memorydevice(dual port RAM) with the current values of the inputs. The controller can read these values at any time, even if the ASI module is simultaneously writing to the dual port RAM.
The ASI module uses a custom gate array for the I/O expanderbus interface. An integrated circuit holds all the control logicand communication protocol. This integrated circuit providesthese functions:• Address comparison and detection.• Message decoding and translation.• Data line filtering of bus signals.
Onboard bus drivers.• Expander bus watchdog.A dual port RAM stores data that can be accessed at thesametime by the controller and the I/O module's microcontroller.Data ValuesFor all inputs, channel values are adjusted based on thefactory calibration. Thermocouple inputs receive cold junction reference compensation. Lead wire resistance adjustments areperformed when necessary (for cold junction reference only).The ASI module provides values to the controller over the I/Oexpander bus. These values are in engineering units.
The ASI module sends a status indication to the controller foreach input channel. This status indicates any hardware errorsand channel configuration errors detected by the ASImodule.
ermination UnitsThe IMASI23 module uses one NTAI06 termination unit to connect to field signals. An NKAS01 orNKAS11 cable connects thetermination unit to the ASI module through its P3 connector.
The termination unit contains RTDs used for cold junction
compensation of thermocouple inputs. They also containthecircuitry needed to convert 4 to 20 milliampere field signalsinto the 1 to 5 VDC needed to input to the analog input 2 - 6 WBPEEUI240774A0
