Robotstudio simulation connected to PLC

Options
Hello,
I'm looking to do the following simulation scenario, and I was wondering how much of this is possible in Robotstudio:

I'd like to have a Siemens s7-1500 PLC (real or simulated, doesn't matter) connected to four simulated robots running in robotstudio.  Then I would like to have that PLC also controlling various other motions on the machine, and those motions appearing in the simulation as well.

-Can I connect the PLC to robotstudio to command the robot to perform jobs?
-Will this work for four robots at the same time?
-Can I connect the PLC to other motions using discrete bits, and have robotstudio simulate these motions?
-Do I need some external software like Simumatic3d to do these extra motion simulations?
-What software packages will I need to order?

Thank you in advance,
KD
