ABB DSTA001 57120001-PX模拟卡模块
事件记录器操作：可以使用此设置点禁用或启用事件记录器。禁用事件记录器时，不会记录任何新事件。启用事件记录器后，将记录新事件，并在A3电源分析\事件记录器中显示40个最新事件。有关可能事件的列表，请参阅第28页第5.4.4节：事件记录器。事件记录器中的所有数据都存储在非易失性存储器中。此功能涉及单独的采样数据流。所有输入通道以每个周期16次的速率连续采样。使用单个周期块间隔，根据以下触发设置点检查输入样本的触发条件。注意，用于所有计量计算的正常采样脉冲串（64个采样/周期，2个周期）是在跟踪存储器采样的基础上完成的。每当请求谐波分析时，谐波分析采样（256个采样/周期，1个周期）使跟踪存储器采样停止一个周期。有关EnerVista PQM设置中跟踪内存实现的详细信息，请参阅第6章
EVENT RECORDER OPERATION: The Event Recorder can be disabled or enabled using this setpoint. When the Event Recorder is disabled no new events are recorded. When the Event Recorder is enabled new events are recorded with the 40 most recent events displayed in A3 POWER ANALYSIS \ EVENT RECORDER. Refer to Section 5.4.4: Event Recorder on page –28 for the list of possible events. All data within the Event Recorder is stored in non-volatile memory. This feature involves a separate sampling data stream. All input channels are sampled continuously at a rate of 16 times per cycle. Using a single-cycle block interval, the input samples are checked for trigger conditions as per the trigger setpoints below. Note that the normal sampling burst (64 samples/cycle, 2 cycles) used for all metering calculations is done on top of the trace memory sampling. The harmonic analysis sampling (256 samples/ cycles, 1 cycle) causes the trace memory sampling to stop for one cycle whenever a harmonic analysis is requested. Refer to Chapter 6 for details on trace memory implementation in EnerVista PQM Setup
