How to use SW_CAM

Is anybody kind enough to tell me how to use SW_CAM.

That's what i have done,but failed.

1.setMD 10450[0]=1;
MD 10450[1]=2;
2.set SD 41500[0]=1200;
SD 41501[0]=1000;
3.active SW_CAM
AM0.1//always one.
=DB31.DBX2.0
Then I look for the result of DB10.DBX110.0 and DB10.DBX114.0.
But however I travel the X axis,both of the two signals keep 0.

Wassomething important missed?

Look forward to your responseding.

Hi Liangjingli - I know it's been a long, long time, but did you ever find a solution to your software cam issue.  I'm trying to use the cam signals for a sensor and I'm stuck in exactly the same place you were.  Did you ever get it to work?
