Hello everyone,

I am trying to connect Factory IO to TIA Portal V18 using PLCSIM (standard version) and the official Factory IO S7-1200 template project.  
The driver in Factory IO connects successfully (shows green and “CONNECTED”), but **input signals from Factory IO do not appear in my TIA Portal program**.  
No input bits change in the PLC, even though the driver window shows them as active.

Here is what I have tried so far:

- All software (Factory IO, PLCSIM, TIA Portal) are run as administrator.

- Windows Firewall is disabled, PLCSIM Virtual Ethernet Adapter is active and set as “Private” network.

- I have matched the input/output addresses in Factory IO and TIA Portal (for example, %I0.0, %Q0.0, etc.).

I have been struggling with this problem for several days and couldn’t find a solution yet.  
I would really appreciate if anyone can help me solve it as soon as possible.  
Thank you very much in advance!

Did you find a solution? I am having the same problem, already tried to change the input to %I10.0 but nothing worked.

Hi @orkun_trabzon_67

From the information you shared everything seems ok and it should work, so I’m not sure how to solve this.  
Could you share your solution? It’d be very helpful for others who face the same problem.
