Adnan Shahid Baig Posts: 4 Rating: (0)	Does S7-1200 has a CAM poistioner function ? I have a 360pulse encoder installed on my machine. I want to take outputs at certain degrees e.g. Q0.0 ON between 20-50degrees Q0.1 ON between 30-45degrees Q0.2 ON between 20-70degrees Is this possible ? Can I take 2 cam positioners ?

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...

There is al little example of using hydraulic valve characteristics (instead of cam functionality) in the following application example: https://support.industry.siemens.com/cs/ww/en/view/109741575
