Multiple Scom Interfaces #3

Open mrphil81 opened 2 years ago

mrphil81 commented 2 years ago

Hi, First of all, many thanks for providing this module. It works pretty well! My current setup is a bit overloaded. I run 3 xtender and each has its own Bus (xtender + BSP). With that setup, I currently have a Raspberry PI Zero for each xtender. Of course thats not ideal, especially because of maintenance, but also because of the power consumption and the coordination between the 3 xtenders (which needs another device). I would rather use one device (maybe a raspi 3 or 4) to communicate with all xtenders. So my question: is there a way to run multiple scom interfaces in parallel? e.g. xtender 1 runs on tty0, xtender 2 on tty1 etc. Since only one devicemanager and therefore one scom is initialized, I would say that's currently not possible.

Hi Mr Phil,

I'll not reply on your question as I don't know the module yet, sorry ;-)
But about the Xtender system I have experience. There exists an "independant" mode when you have multiple units: param 1462 With that mode you can have all three Xtenders working together on the same Studer-bus but not synchronized as if it would be in parrallel or in threephased. This will be OK if you have one battery and one BSP in a system as multi BSP is not possible.
Maybe that could fit your case Regards

Hi moixpo Thanks a lot for the hint. I didn't know that. I would stick to the 3 independent battery systems, since that setup has also some advantages. especially if you have huge stack of lead-acid batteries that need a full load every couple of days, that maintenance load can be done independently. Regards, Phil
