回复:你的解释不对,请看这里from Training Center //Re:并联一个SM0.0。
s5 没有sm0.0, 不象s7-200.
一个简单的方法:
if you want to set I0.0=0, then write the following structions in the top of OB1.
A I0.0
AN I0.0
=I0.0
..........................
if you want to set I0.0=1, then write the following structions in the top of OB1.
O I0.0
ON I0.0
=I0.0
That is OK.
