Hi, I am creating a simulation of a pressure test in Ignition Vision 8.1. As a new Ignition user I tried to increment a tag write in a loop, which freezes the client, as everyone said it would in previous posts I now see! My Ignition is connected to Kepserver so I created a ramp simulator tag and can see the value change in Ignition okay. So, I thought I would be able to grab the Kepserver address of the tag, RAMP (120, 35, 100, 4), and zero it before the simulated test starts, then write a new address based on the recipe for the pressure test when the test starts. But, using `tagConfig = system.tag.getConfiguration(tagPath)` I can see everything but the address!! Is it possible what I want to achieve? And before I go down the wrong path, how would I script this? Regards. ---

I thought I could answer this myself..... just create a string tag and point it to the Kepserver tag address value. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/9/990783bbc4ccc2954f98560ebff17ce2c3d2ffae.png) However, all Kepserver simulations can not be set to read and write!!!! Even when creating a new tag entirely from Ignition script! So, I still do not know how to simulate a ramp tag value for a pressure increase simulation. ---

You can also download @pturmel simulation aid's module. It has a ramp function like you're looking for and he provides a sample project where he uses it to simulate tag values. ---

Thank you, can you point me to this module? ---

I managed to simulate a pressure test using Gateway timer scripts and then forcing the expressions in expression tags to follow the timer... or not. Thank you for your help also - I will check this out. Much appreciated.
