Question about connecting other SCADA simulations to an EPANET-RTX sim

Hi there, not sure if this is a silly question or not, but I need some clarification. There is currently a power grid testbed that I would like to connect to a similarly live simulation of other critical infrastructure, such as a water network, to create some kind of interdependence between the two. That is to say, actions on one system could propagate to another. We found EPANET, but are aware that it isn’t really meant to support a testbed. I was wondering if EPANET-RTX could provide that functionality? Or is it limited to just creating more robust, although independent, simulations.
