Manual setting of IP address for modbus TCP?

Hi,

I have a self-made energy meter which I converted to communicate via ModBus TCP such that it behaves the same as the EM24. I have tested it via the Carlo Gavazzi UCS 7 software and also other modbus software sniffers can find the device in the network.

I have turned on ModBus-TCP in the remote console.
But somehow Victron is unable to find the device via “scan for devices”.

Is there a way to put in the IP adress of the modbus manual in the Multiplus II GX?
Or any other tips how for settings in the ModBus TCP either on the Victron Multiplus or on the fake EM24, to find the device?

Aha I found the option:
In menu “ModBus TCP/UDP devices” there is the option under “saved devices” when you press "
ADD".
Now I have to see if the device communicates with the Victron

Sadly it does not show-up under “Modbus/TCP” available services.

Any tips?
