Mechatronics Concept Designer SiL-Interface to Siemens Soft-Controller

Mechatronics Concept Designer in NX 12 provides a new interface to PLCSIM Advanced, which is the virtual representation of a Siemens SIMATIC S7 15XX PLC.

This direct interface to a virtual S7 15XX PLC enables MCD to connect the digital twin of a virtual machine to the PLC control logic which is executed by the virtual PLC. 


(view in My Videos)


As shown in the video above the digital twin of the machine on the left side is connected with the virtual PLC instance "PLC_1". The virtual PLC is controlling the process of the machine by writing output signals (actuator signals) to and reading input signals (sensor signals) from the digital twin of the machine . The sequence of operations of the machine including the fail safe behavior is defined by the PLC program which can be tested by using the digital twin of the machine connected to the virtual PLC.


Hello @JochenMerhof ,


simple and short question:


How to connect Siemens NX + MCD with the "old SIMATIC - World"  ?


(I don't have a licence of PLCSimAdv yet; also we are still using SIMATIC in some projects)


I just want to know if there is a direct connection like PLCSimAdvance.

(I am not asking for OPC, WebServices, TCP and so on.)




Thanks in advance



I think only hardware-in-the-loop is possible.


But if anybody has suggestions, feel free to share your information.



I found a Solution:  SIMATIC PLCSIM    --->   Siemens SIMIT   ---->  Siemens MCD
