Hi all. I am working on a BMS project with a lot of devices. I am new to BACnet. I have a few field panels behind which are field level networks with more devices. We are using Siemens equipment. I have added the field panels to ignition and, by using the BACnet driver, I can read data from the local IO of the field panel. However, I cannot see the FLN level devices. Please can someone suggest how to read data from the FLN? Thanks Best regards John ---

They won’t just “show up” underneath the panel devices you added, you have to add a remote device instance for every one you’re interested in. If the panel device acts as a BBMD you may need to specify that in your local device configuration before you can communicate with the FLN devices. ---

Thanks Kevin. We have Siemens PXC panels. The panels are sending FLN data to a Desigo CC instance on the network but I’m struggling to get it into ignition. If I set up new remote points (in ignition) with the BACnet IDs for the FLN devices, they do not respond/initialize. I’ve also tried a third party BACnet explorer which was unable to locate the devices. I will look into the configuration of the panels later today. Any other ideas? Thanks again. ---

Access to the FLN devices is going to be entirely dependent on the panel device either acting as a BBMD or relaying whoIs broadcasts to the FLN devices and then broadcasting their iAm responses back onto the network. That a 3rd party BACnet explorer can’t see them either doesn’t bode well. I don’t have much more advice to offer, I’m a bit of a BACnet n00b despite having worked on this driver. ---

OK. I will see if I can find these settings in the panel config. I wondered if Desigo was communicating with the FLN devices via a proprietary protocol (not BACnet). Snip from the PXC compact manual: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/c/3c3a3ec23ed9b3937f413d20fadc1c4807b15a9e.png) I appreciate the help and I will report back with any findings. ---

@eichler-eng, were you able to work this out? I am in the same situation currently, and from what I have gathered, it _may_ be a BACnet Routing setting in the PXC Controllers, which can only be accessed via the Siemens ABT or SET software. Before I further my quest, I figured I would ask. Thanks! ---

Apologies for the very slow reply! Unfortunately, my client did not want to progress the project any further, so I never got to the bottom of the issue. Best of luck. ---

Hi guys, we are currently going through this as well. Have you come up with a solution? We have 3 Siemens PXC modular BACnet controllers which we are able to pull data from BUT we have 177 Siemens PXC IP, NON-BACnet controllers that we are not able to communicate to. Are there any integration drivers I am not seeing? Thanks, Jason
