Commissioning with real plc

Hi, everybody.

I'm a student and I'm surveying for the best process simulation software.

I found Delmia one of the bests but I want to communicate with real plc and I searched about that I found something under the term of delmia plm and one another under the term of delmia automation. I didn't find anything about delmia automation or plm on the web that I could refer as a reliable reference.

I want to know what of the two mentioned above is real. I find siemens nx and SolidWorks for this purpose but still, I'm hesitating about delmia.

I'll be thankful if someone helps me.
