Hello,

I am trying to repair a lighting system at a hospital and they have Tridonic DALI MSensor 02 motion sensors in the DALI loop connected to the Crestron DIN-DALI 2.  I have not ever needed to make use of motion sensors on a Crestron system that wasn't a Crestron sensor.

Does anyone perhaps have any insight into how I might be able to read the motion trigger on my processor?  We have a CP3N in place and so far the only thing that seems to look like it may work is the Three-Byte Command in SIMPL on the DIN-DALI-2 Loop modules, but I do not know how to read the information from the sensor.

Regards,

Hi Hugo;
study the manual for the Tridonic:
https://resources.tridonic.com/PDB/Ressource/Web_TR/brochures/en/DALI_MSensor02_ProductManual.pdf

If I read it correctly, the sensors should be in Slave mode; their addresses will have to be known and you'll have to periodically poll every sensor for motion status.
I'd be using the "Ballast 2-byte command" to send DALI command #160 (Query Actual Level) and parse the 8-bit response (actually for presence detection you only care about the 1st bit according to the Tridonic manual).
Hope this helps..

Hi Igor,

 

Thank you and sorry for the late reply.  My mails from here seem to be bouncing back.  I will definitely play with this a bit more.

Regards,

Thanks Andrzej,

This is what we ended up doing as we were running short on time.  Thank you for taking time to reply.
