Cerbo GX doesn't see Ethernet ModBus TCP/IP ComAp InteliLite AMF8 via CM3-Ethernet plugin card

I've purchased hardware from ComAp, based on documentation from https://www.victronenergy.com/media/pg/Cerbo_GX/en/connecting-supported-non-victron-products.html#UUID-73fa2d0e-1d42-a05f-5dc2-c81c6273659a

But I can't seems like get it visible via my Venus OS

I can read/write device via ComAp InteliConfig windows software as well as via Android ComAp app

Venus OS latest Release Candidate can't see it via Ethernet, even if I add manually via ModBus TCP/IP devices. Venus on Cerbo GX, same network, can ping from Venus.

Feels like modbus registers are different than in Victron documentation, but I'd rather receive confirmation from Victron how to fix this, instead of digging into table of hundreds of unknowns...


Could you help to get this hardware visible/controllable via Venus UI?

InteliLite4-1.5.2.1

CM3-Ethernet

Cerbo GX

Thank you @Philipp Trenz for contacting me in person

After uploading your config.zip

My Cerbo GX started to see AMF8 hardware via Ethernet

This is how it looks now - I have configured via InteliCongif it to become 1phase config, but Cerbo is showing it as 1p->3p->1p

See video


Disclaimer - I have no any generator just yet. It just ComAp + CM3-Ethernet plugin card connected via 12V power supply and Ethernet cord to LAN


Amy futher help appreciated

Hi @Andrii Podanenko, yes, it seems like some generator manufacturers configure a Modbus mapping other than the one expected from the Victron system. Please take a look at this thread for instructions: https://community.victronenergy.com/questions/240475/establishing-modbus-tcpip-connection-with-comap-co.html?childToView=253977#comment-253977

Config from that thread didn't fit my hardware, that's why I started a new question

As I shared somewhere else - there is no generator just yet. It's only electronics from ComAp on a table
