and welcome to the PLM Community.
You need to be a bit more specific where you need help with the Mechatronics Concept Designer.
We need more Information to work with, for example:
Do you have already have a model in MCD?
Are you struggeling at a specific task or feature?
What kind of PLC do you want to use?
you have different options here I will list the 4 most common used here:
sorry i cannot send you the Simit Project because I have none that I can share.
For examples / more information for Simit, Scout and Simatic products you have to contact your specific support and / or your regional Account Manager.
It also probably makes sense to visit a training or specific workshop for the products above, there are also partners and ofcourse Siemens internal expertise that you can contact on the matter.
In this Forums we mainly support the PLM Products, that beeing said, if you have specific problem or questions about MCD / NX / Tecnomatix or Teamcenter, feel free to ask them here.
