我尝试用python中的pyfanuc（https://github.com/diohpix/pyfanuc）库从cnc fanuc读取数据。
我能够读取pmc变量，宏变量，但我试图读取0i fanuc参数号的部件计数。6711（来自0i fanuc pdf https://www.fryermachine.com/pdf/support/programming/fanuc0i/Fanuc%20Series%200i%20MODEL%20F%20Plus%20Parameter%20Manual_B-64700EN_01.pdf第390页）。

from pyfanuc.pyfanuc import pyfanuc

conn=pyfanuc('192.168.8.223')
if conn.connect():
    #read pmc
    n=conn.readpmc(1,9,3712,1)
    print(n)

    #read macro
    n=conn.readmacro(9723)
    print(n)

    #read param
    n=conn.readparam(conn.ALLAXIS, 6711,0)
    print(n)

    #console print
    #461
    #0.0
    #None

有人能帮我吗
