bacnet IP - ALEJANDRO - 12.03.2026
I have three logic machines connected to my network, for some reason I can't see them through bacnet ip, maybe I've configured something wrong in bacnet settings.

Explain how you are testing BACnet connectivity. In LM you need to enable BACnet server in System config and enable "export" property for objects that must be visible in BACnet.

OK, ONE MOMENT
This is one of my LMs
RE: bacnet IP - admin - 12.03.2026
This is Modbus, not BACnet.
Please explain in detail what exactly are you trying to do?
RE: bacnet IP - ALEJANDRO - 12.03.2026
upps, sorry
Now, You can see
This is very strange.
I try to look LM2 and LM3 from LM1
I was trying to get data from LM2 and LM3 and send it to LM1

This bacnet client app is very limited and it can only handle arond 50 objects. If you use more then you will struggle. Make sure to not enable bacnet server on the device wher bacnet client is used.
I strongly reccomend to uninstall this app and do the integration in Script with direct connection mode. Use single resident script for reading and event scripts for writing.

You will need backnet package for this https://dl.openrb.com/lm-25-imx6/pkg/
If I understand your problem correctly that you have two LMs with exact same group structure and you must individually map them to 3rd LM as they can't overlap then the simplest solution which does not require any scripting is to use different aprouch.
You can use MQTT Client app (not MQTT cloud) and local Broker app and then you can just individually link objects to MQTT topic. This way you have 100% freedom how this will be linked between groups. In a Client app you just select a group and give it Topic name, This name must be used on another LM in Client app and mapped to another group. There is no need for any additional conversions. Between LMs this works out of the box.
Client app must be on all LMs and on one you need broker and all clients must be connected to this broker.
See this video, its super simple

As you can see on the LM where broker is inslalled I'm using 127.0.0.1 as host IP as this is on the same device.
