NodeRed on Multiplus GX (Large) - Modbus Server Node (EM24 simulation) not visible

Hello, i have a working node-red flow which is simulating an EM24 over an modbus server. NodeRed is running on a seperate machine with Home Assistant and Node Red.

This is used for a Modbus Power Meter for the PV-Values. It is visible in Venus OS as an Modbus TCP Device

I want to run this flow on the integrated Node Red in the large version. The input of the values (Modbus-TCP and JSON) ist working, but not the Modbus server. I've tried different Modbus ID's and Ports with no sucess.

Is it possible to run it on the same machine (GX on Multiplus-II)?

Maybe this driver could help you. It's not Modbus, but you can write the values over Node-RED and MQTT to the dbus: https://github.com/mr-manuel/venus-os_dbus-mqtt-grid
