從PLC（micrologix 1100）獲取數據到python

Question

我正在尋找使用python獲取數據的PLC，使它做了很多工作，我只需要得到「0」和「1」的值。這個Python庫pycomm（https://pypi.python.org/pypi/pycomm/1.0.7）這是哪裏片斷太：

from pycomm.ab_comm.slc import Driver as SlcDriver 


if __name__ == '__main__': 
    c = SlcDriver(True, 'delete_slc.log') 
    if c.open('172.16.2.160'): 

     print c.read_tag('S:1/5') 
     print c.read_tag('S:60', 2) 

     print c.write_tag('N7:0', [-30, 32767, -32767]) 
     print c.write_tag('N7:0', 21) 
     print c.read_tag('N7:0', 10) 

     print c.write_tag('F8:0', [3.1, 4.95, -32.89]) 
     print c.write_tag('F8:0', 21) 
     print c.read_tag('F8:0', 3) 

     print c.write_tag('B3:100', [23, -1, 4, 9]) 
     print c.write_tag('B3:100', 21) 
     print c.read_tag('B3:100', 4) 

     print c.write_tag('T4:3.PRE', 431) 
     print c.read_tag('T4:3.PRE') 
     print c.write_tag('C5:0.PRE', 501) 
     print c.read_tag('C5:0.PRE') 
     print c.write_tag('T4:3.ACC', 432) 
     print c.read_tag('T4:3.ACC') 
     print c.write_tag('C5:0.ACC', 502) 
     print c.read_tag('C5:0.ACC') 

     c.write_tag('T4:2.EN', 0) 
     c.write_tag('T4:2.TT', 0) 
     c.write_tag('T4:2.DN', 0) 
     print c.read_tag('T4:2.EN', 1) 
     print c.read_tag('T4:2.TT', 1) 
     print c.read_tag('T4:2.DN',) 

     c.write_tag('C5:0.CU', 1) 
     c.write_tag('C5:0.CD', 0) 
     c.write_tag('C5:0.DN', 1) 
     c.write_tag('C5:0.OV', 0) 
     c.write_tag('C5:0.UN', 1) 
     c.write_tag('C5:0.UA', 0) 
     print c.read_tag('C5:0.CU') 
     print c.read_tag('C5:0.CD') 
     print c.read_tag('C5:0.DN') 
     print c.read_tag('C5:0.OV') 
     print c.read_tag('C5:0.UN') 
     print c.read_tag('C5:0.UA') 

     c.write_tag('B3:100', 1) 
     print c.read_tag('B3:100') 

     c.write_tag('B3/3955', 1) 
     print c.read_tag('B3/3955') 

     c.write_tag('N7:0/2', 1) 
     print c.read_tag('N7:0/2') 

     print c.write_tag('O:0.0/4', 1) 
     print c.read_tag('O:0.0/4') 

    c.close() 

恕我不得而知，但我需要知道，如果是足夠多的「改變」（172.16.2.160）IP鏈接到的唯一的事情PLC的，對不對？

「並選擇正確的標籤」

感謝您對未來的幫助，對於這個「難得的問題」抱歉，我現在不能用PLC測試代碼。 （可能在幾周內）所以我不能成功地嘗試這部分代碼。如果你知道另一個python庫，請告訴我那個選項）

Answer 1

更改IP地址就夠了。
