Hello everyone,

I have a problem with my factory io not responding to my plcsim tia portal v19. The plcsim connects to Factory IO but it’s not responding even when I try to run the conveyor manually  
via Factory io it’s not running. Any idea why this happens?

I deleted FactoryIO and reinstalled it and works now. Try that!

Hello @valentinvelazquez147

Welcome to the forum!  
Could you please share some more details about your issue?  
Do you get any error on Factory I/O when you try to connect?  
What version of TIAPortal and PLCSIM are you using?  
Have you had a chance to check our [tutorial on how to connect Factory I/O and PLCSIM](https://docs.factoryio.com/tutorials/siemens/setting-up-s7-plcsim-v13/)?
