We have developed a simulation module (UNISEMS) that can integrate with Ignition directly thru a GCM module or thru OPC-UA (you will have to expose all tags thru OPC UA interface for this). However the simulation models will have to be written in GNU FORTRAN. See [Introduction](https://youtu.be/XpPv2KWk4c0) and Demo of [UNISEMS](https://youtu.be/249R5l3rELs). of UNISEMS module.

As you are writing your simulator in Python , UNISEMS will have to be slightly modified to suit your requirements.
