Hi,

the S7-1200 doesn't have CAM function, like the FM351 of S7-300, however you could make something by user program. If you time response requirement are enought, you can do it in OB1 or OB200 at some scan rate (in this case, is just a case of comparation of the encode input value). You can also use interruptions and HSC Control block to set comparations values...

Good afternoon Denilson,
Could you help me with an application that reads the incremental encoder
through HSC and I need to make a move relation to output PTO, as if it 
were an electronic cam.
Thanks!​

Split from CAM Positioner Function in S7-1200.

Hi Mister T,

Greatful for your answer.
But this sample it´s a S7-1500 application, and I´m developing to S7-1200.
I found the block MC Command Table, where it´s possible input the movement steps.
Now I´m trying to set velocity in wich step to PTO according the position from HSC Incremental Encoder.

If you have some knowlegment to share it will be great!

Thanks!!!
