Hi everyone!
I woukd like to start thread, where everyone could share their json files for modbus tab of LM and HL
I will start
daikin rtd-ra gateway profile in attach
daikin instruction is here
Hello,
I would like to know if I have the possibility on this type of material (CHUBB) to recover the information on an LM or SL.
Please find enclosed the documentation provided by the manufacturer.
the JBUS addresses in the excel file must all be entered in the SL ??

Hello,
You should create a new thread for this kind of question.
I didn't see mention of modbus in your documentation, so I don't think you can connect it using modbus.
But it look like it's able to communicate using RS232, which is possible with LM / SL.

Hi AEK,
This .json file for all daikin's product or not ? I want to read directly modbus RTU from VRV by HL but i don't have modbus profile of daikin's . I only have Home automation interface adapter.

hi, my profile was made only for 1 device (daikin rtd-ra gateway).
you can create profile for your device. its not hard.
dowload some profile from this post and open it vai Notepad (better use notepad++). you will see what its exist of.
and use this documentation http://openrb.com/docs/modbus.htm to modify downloaded example

Thank for your support, I will try my best to write my profile for my device.
Hi to all.
As I have never used the LM4 modbus, has anyone already implemented any modbus profile for connecting to SunSpec compatible PV inverters?
The one I need to communicate with has the attached description of modbus information.
I could use some initial help to start with the modbus...
Thank you all in advance
Start with RTU read test and read a register with a known value. You need to subtract 1 from the documented register address and probably you need to ignored thousands part, so holding register address 40070 is actually 69 and so on.
This RTU table was provided by the suppliers of the controller, I do not know how universal it is, but I think it will be useful.
Also, by reference, you can see all the documentation for the controller and the protocol description for this configuration.
P/S
I also tested this profile with the Segnetics SMH2010 controller, the main variables that I need for monitoring are the same as on the Pixel controller...

Hi,
I've been working on a modbus profile and I've seen that when a value from the modbus slave changes, LM sends its value to KNX over tcp line but it's not sent to twisted pair...
Am I wrong? Is it possible to send it to twisted pair automatically as it changes?
Thanks.

Solved! I've seen that on the object mapping is an option "Write to bus"...
Is it possible to define this value inside the Json file?
Thanks.
I find the world of Modbus an endless case of confusion. Although I've been successful interpreting most documentations, I'm struggling a bit with this one:
There a reference to register 0020H - would that be register 32 as according to my HEX calculator (Ignoring the H, as that will output an error)? I see that register will post a status of numbers and letters, what DT would that be in the group address then?
You can either parse the contents using a script or you can create a separate profile entry for each bit. Then you need to set bus_datatype to bool and use value_bitmask for each entry. Mask table for all 16 bits:
Code:
bit 0 = 0x1
bit 1 = 0x2
bit 2 = 0x4
bit 3 = 0x8
bit 4 = 0x10
bit 5 = 0x20
bit 6 = 0x40
bit 7 = 0x80
bit 8 = 0x100
bit 9 = 0x200
bit A = 0x400
bit B = 0x800
bit C = 0x1000
bit D = 0x2000
bit E = 0x4000
bit F = 0x8000
