ICS TRIPLEX T8314工控备件机器人模块
需要从469中读取电流（寄存器地址0306h）和热测试定子RTD温度（寄存器地址0320h），其地址可重新映射如下：1。使用功能代码06或16将0306h写入地址0180h（用户可定义寄存器索引0000）。2.使用功能代码06或16将0307h写入地址0181h（用户可定义寄存器索引0001）。（平均相电流为双寄存器数）3。使用功能代码06或16将0320h写入地址0182h（用户可定义寄存器索引0001）。寄存器0100h（用户定义寄存器0000）和0101h（用户可定义寄存器0001）的读取（功能代码03或04）将返回A相电流，寄存器0102h（用户可自定义寄存器0002）将返回热测试定子RTD温度。注：GE Power Management 469电机管理继电器6-17 6通信6.4存储器映射6 6.4.3事件记录器469事件记录器数据从地址3000h开始。地址3003h是指向感兴趣事件的指针（1表示最新事件，40表示最早事件）。要检索事件1，请将“1”写入事件记录选择器（3003h），并从3004h到3022h读取数据。要检索事件2，请将“2”写入事件记录选择器（3003h），并从3004h到3022h读取数据。可以以这种方式检索所有40个事件。每个事件的时间和日期戳可用于确保按顺序检索所有事件，而新事件不会破坏事件序列（事件1应比事件2更近，事件2应比事件3更近，等等），由S1首选项、跟踪内存缓冲区中的设置点确定。跟踪存储器触发器在S1首选项中设置，这决定了存储了多少行程前和行程后循环。跟踪缓冲区带有时间和日期戳，并且可以与事件记录中的行程相关。当跳闸发生时，以这种方式捕获10个波形。这是3相电流、3个差分电流、接地电流和3个电压波形。该信息存储在易失性存储器中，如果继电器通电，该信息将丢失。要访问捕获的波形，请通过将其跟踪存储器通道（见下表）写入跟踪存储器通道选择器（地址30F1h）来选择感兴趣的波形。然后将跟踪存储器数据从地址3100h读取到3400h。每个周期有12个样本。读取的值以实际安培或伏特为单位。地址30F8h显示采集的记录道数。要访问最新版本，请使用地址30F0h处的值。要访问多个跟踪，请减小此值以访问较旧的跟踪。跟踪记忆通道波形0相位A电流1相位B电流2相位C电流3差分相位A电流4差分相位B电流5差分相位C电流0430跳闸总数0 50000 1-F1 0 0431不完整序列跳闸0 50000 1-F1 0 0432输入开关跳闸0 50000 1-F1 0 0433
Current (register address 0306h) and Hottest Stator RTD Temperature (register address 0320h) are required to be read from an 469, their addresses may be remapped as follows: 1. Write 0306h to address 0180h (User Definable Register Index 0000) using function code 06 or 16. 2. Write 0307h to address 0181h (User Definable Register Index 0001) using function code 06 or 16. (Average Phase Current is a double register number) 3. Write 0320h to address 0182h (User Definable Register Index 0001) using function code 06 or 16. A read (function code 03 or 04) of registers 0100h (User Definable Register 0000) and 0101h (User Definable Register 0001) will return the Phase A Current and register 0102h (User Definable Register 0002) will return Hottest Stator RTD Temperature.

Address 3003h is a pointer to the event of interest (1 representing the latest event and 40 representing the oldest event). To retrieve event 1, write ‘1’ to the Event Record Selector (3003h) and read the data from 3004h to 3022h. To retrieve event 2, write ‘2’ to the Event Record Selector (3003h) and read the data from 3004h to 3022h. All 40 events may be retrieved in this manner. The time and date stamp of each event may be used to ensure that all events have been retrieved in order without new events corrupting the sequence of events (event 1 should be more recent than event 2, event 2 should be more recent than event 3, etc.). 6.4.4 WAVEFORM CAPTURE The 469 stores a number of cycles of A/D samples each time a trip occurs in a trace buffer, determined by the setpoint in S1 Preferences, Trace Memory Buffers. The Trace Memory Trigger is set up in S1 Preferences and this determines how many pre-trip and post-trip cycles are stored. The trace buffer is time and date stamped and may be correlated to a trip in the event record. 10 waveforms are captured this way when a trip occurs. These are the 3 phase currents, 3 differential currents, ground current and 3 voltage waveforms. This information is stored in volatile memory and will be lost if power is cycled to the relay. To access the captured waveforms, select the waveform of interest by writing its trace memory channel (see following table) to the Trace Memory Channel Selector (address 30F1h). Then read the trace memory data from address 3100h to 3400h. There are 12 samples per cycle for each of the cycles. The values read are in actual amperes or volts. Address 30F8h shows the number of traces taken. To access the latest use the value at address 30F0h. To access more than 1 trace, reduce this value to access the older traces.
