Is there a way to simulate PLC realtime data without actual PLC? I remember in one of the tests as integrator, there was CSV file sent to simulate such behavior. How do we do that by ourselves? Thank you very much. ---

Heh, sounds familiar 🙂 Take a look at [this thread](https://inductiveautomation.com/forum/viewtopic.php?f=50&t=14532). ---

Hi, pturmel Thanks! Looks like this is what I look for! Will go and check. ![:thumb_left:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/e26afb081ddde6df016df6ee49159cf56aaca688.gif ":thumb\_left:") ---

Hi pturmel, I run your project “Simulation Aids Module Demo” in my PC and I got the following error, any idea?

Pardon me, > [@](#): > > You didn't load the module into your gateway 1. What module do I need to load? objectScript? 2. How do I check the version of the module loaded to be fit with the project? Thanks! ---

That’s also where you get to the module install page (at the bottom of the list). ---

That works really well. Thanks! 😃 What I previously had was “Production-Simulator” module (as it was instructed during the test to use this module). It turns out to be different module from “Simulation Aids” (I didn’t know this). Thanks for the clarification! ![:thumb_right:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/2026e28c0c425034352c1b75807edf956adc75f4.gif ":thumb\_right:")
