Question

我正在寻找使用python获取PLC的数据，以便用它做很多工作。我只需要得到＆＃34; 0＆＃34;和＆＃34; 1＆＃34;值。我发现这个python库pycomm（https://pypi.python.org/pypi/pycomm/1.0.7）这个片段也在哪里：

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()

请原谅我的未知，但唯一能让我知道的是否应该知道＆＃34;改变＆＃34; （172.16.2.160）ip链接到PLC，对吧？

＆＃34;并选择正确的标签＆＃34;

感谢您对未来的帮助，并对此感到抱歉＆＃34;罕见问题＆＃34;我现在不能用PLC测试代码。（也许在几个星期内）所以我不能成功地尝试这部分代码。我需要开始在另一部分工作。（只是为了确保我能用python获取数据。如果你知道python中的另一个库请告诉我那个选项）

Answer 1

更改IP地址就足够了。

从PLC（micrologix 1100）获取数据到python
