Bacnet server and Client
#1
Hi,
 
I have a project where i want to use the LM5 as a scene controller, the LM will control 13 Wago PLC with Dali cards.. I have also 16 HMI screens that will send scene commands to the LM.
The communication is Bacnet ip
 
Is it possible to use both server and client at the same time? And is this possible to do without a lot of scripts?

Hi Evens!
you can use both server / client. Just make sure to use on different ports.
The server is straightforward, see here. The client requires some scripting, but ready commands are described here. Good luck!

Hi,

It does not make sense to have server on BAC0 and client on BAC1, they won’t be able to communicate with each others BACnet networks.

I also don’t see the use case, you can bind all from the client, but if you really need this i would use 2 controllers.

PS: We launch BACnet Client App soon for our controllers so you won’t need script anymore to bind BACnet objects to KNX objects.

Hi,

Thanks for the reply! Smile

The idea is that the HMI touch screens will operate the local dimming directly to the PLC. But all Scene goes thru the LM. the reason for that is easy changing of scene values, and easy programing.

Regarding Bac0 and Bac1, im totally new to Bacnet, so this is very good information Smile
Regarding using one or two LM, im not Shure what to do here, because the HMI will not communicate directly thru the LM to get to the PLC. Its only to run a scene, LM will then write to the PLC.

Edgars and Erwin what is your opinion? This project is on a big cruise vessel, so very important that it will work properly Smile

Hi,

I think you only need the BACnet client package to run your scenes to the dimmers. You can disable the server on the LM.

Hi,

That`s correct, but i need the server to communicate to the HMI touch panels.
Because the Wago plc will be a server, and the HMI a client, so that’s why the LM needs to be both. Or have I misunderstood?

Hi,

Why do you need to communicate with the client HMI? When you send a new value to Wago PLC from LM, the HMI client will notice that if i'm not mistaking

Hi,

That is correct. But the HMI has the scene buttons, so it needs to send a scene value to the LM. No need for communication from the LM to the HMI. Only HMI to the LM.

Hi,

In that case, yes you need to host the LM objects to the client, i think you need 2 controllers...

Hi,

Thanks! Smile Its probably the easiest also.
This Bacnet app, is it only for Spacelynk or is it also for LM ?

Hi,

The app is developed by Schneider but i see most of our apps also in the LM (and the other way around), i think it does but you can better ask admin if they have agreed to share it.

Schneider developed only the GUI. All the low level bacnet code comes from EMBS Smile
