NI SCXI-1127通道继电器多路复用器
新的计算值被写回到CI854/CI854A的设置选项卡中,并存储在项目中,如图17所示。下图显示了自动PROFIBUS主参数计算的不同步骤。如果从设备不支持所选波特率,系统自动选择所有从属设备支持的下一个较低波特率,并将该波特率下载到控制器中。除了将计算的PROFIBUS参数写回设置选项卡之外,计算结果和一些额外信息将发送到名为PROFIBUS_DPV1_calculation.txt的文本文件中。该日志文件位于日志文件目录中,文本文件包括当前和以前的计算,最大大小为1兆字节。当前计算结果位于文件末尾。
The new calculated values are written back into
the settings tab for CI854/CI854A and stored in the project as shown in Figure 17.
The following figure shows the different steps for the automatic PROFIBUS master
parameter calculation.
If a slave does not support the selected baudrate, the system automatically selects
the next lower baudrate supported by all slaves and downloads this baudrate into
the controller In addition to the write back of the calculated PROFIBUS parameters into the
settings tab the calculation result with some extra information will be sent to a text
file named Profibus_DPV1_Calculation.txt. This logfile is placed in the logfile
directory, called LogFiles, of Control Builder M. The text file includes the current and previous calculations up to a size of 1 Mbyte. The current calculation is placed
at the end of the file.
