pyprofibus:为PRM找到合适的配置和配置

Question

我们以前有一个功能程序在转换器上运行pyprofibus，并附带一个gsd文件HMS_1810.gsd。运行该程序的计算机有一个来自HMS的Profibus-DP主仿真器，连接在传感器的串口上，电缆的另一端作为usb适配器( linux系统上的接口dev=/dev/ttyUSB0 )。

现在我们想要使用pyprofibus，除了使用M40的换能器的新模型和HMSB1815.gsd变体之外，硬件设置基本相同。还不清楚新的pyprofibus.conf文件应该如何引用每个新模块。从我在gsd文件中看到的情况来看，它现在使用的是DP-V1而不是DP-V0。

当我运行新程序(附加"frequency_reader_new.conf“、"frequency_reader_new.py”和"HMSB1815.gsd")时，我得到了响应：

config: <pyprofibus.conf.PbConf object at 0x7feaa09c83d0>
master : <pyprofibus.dp_master.DPM1 object at 0x7feaa076eb40>
<pyprofibus.conf.PbConf._SlaveConf object at 0x7feaa09c8ac0> -- done!
<pyprofibus.dp_master.DPM1 object at 0x7feaa076eb40> -- initialized
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).
DPM1:  >ERROR<  Slave 5 reports a faulty configuration (Chk_Cfg).

• 考虑到上一个程序中的dp1Prm设置非常简单，那么只在新程序中运行类似的设置可以吗？
• 在前面的程序.conf中，所使用的模块在模块名称之后使用了相关的“字节码”。在新.conf的上下文中，每个使用的模块应该使用哪个字节或全部字节？
• 确切地说，Chk_Cfg参数是错误的吗？

晚上好。我已经与gsdparser.py核对过，您的gsd文件对于pyprofibus是一致的。

解析器

看起来pyprofibus正确地识别了gsd文件，没有任何错误。因此，对于我来说，由于不通晓python文件是正确的，而且您在frequency_reader.py中有错误的参数。我想使用这个库从profibus值中读取来自的数据，使用廉价的rs485 usb转换器。你对这个图书馆有什么经验？这个库有用吗？我从来没有与profibus建立连接，因为我没有任何profibus dp设备可以连接。我在做dummy_slave。到目前为止，我已经创建了Tkinker，并与其进行了精确的沟通。

基于USB COM3的Profibus总线 --我注意到，在没有线程的情况下，通信会减少。仍然在寻找一些设备来检查通信是否正常。
