Looking for users with OCI351 ModBus Clip-In

[fredlcore]

In this document, Siemens provides a lot of information how status registers can be read/written via ModBus. These are then translated and sent via LPB to the connected heaters: https://www.riello.com/spain/productos?action=download&id=20185704-00e586f9ff2ad720b7e34cd7e1399abb

If someone is using this ModBus Clip-In, we could see these LPB telegrams and identify what meanings they have and then use this information to generate new status parameters for BSB-LAN. Therefore, everyone who can contribute, please join here!

I believe the rather new Elco Aerotop SPK Series (R290 refrigerent) used modbus with the OCI351 clip-in on a Siemens RVS61.843/560 Serie F. I noticed this is a different setup than with other monoblock devices from Elco like the SX-Series.

Stumbled upon this project, when I tried to figure out how to interface with these Elco heat pumps. (don't have one, just doing research)

Yes, that would be such a combination I'm looking for. Basically, all LMS14/15 and RVS21/61 controllers would fall into that category...
