Hi, Sweti3!

Can you be so kind and send me the service code for the aqotec rm360? Thank you!!

Hi all,
does anyone have the full Modbus Register list of the RM360 controller? I have found one with ~50 registers only but I think the controller has around 1000. Would be great if the list with all register addresses could be shared.
Thanks!

I am not sure if the service code is the same for all RM360 but in my case it was 1234

I asked the Aqotec support about the missing addresses and they told that the list only contains the “open” addresses, theoretically all service level 2 parameters can be read/written.
The main problem with writes is, that they write directly into the register which might damage the controller if it happens to fast.
If you really need more then the provided addresses I suggest to ask the support directly, in my case they replied in under an hour.
