Help me Binding Modbus 1.9.0 holding

omar1971 · November 28, 2016, 10:01pm

Who can help me.
It has long been expected that the time of a binding update but I can not make it work.
My equipment (DFTS) communicates with Openhab via serial RS232 and Modbus RTU binding.
The DFTS technical specifications say that contains a RAM memory organized in 16-bit registers each (Word).
Each Word contains information regarding the status of the bus modules connected to DFTS, then returning values or input bits and set values or bits to control the outputs.

The inputs can view them while the outputs I can not control them.
Technical support recommends the MODBUS RTU functions that should be used are:

To read any Word: Function 3 (read registers)
To write any Word: Function 16 (Write multiple registers)

To act on the individual on the individual points (virtual or real) you must act on the relevant Word bit to be understood in decimal format
(Thus the function 16 is to be understood 16 decimal, that is to say 0x10 hex)
The syntax is that used in MODBUS RTU protocol.

Could you please make a minimal config, with single slave, and single item bound to that slave? Then take verbose logs from that and paste to pastebin.com

You mentioned that the reading worked but writing did not, did you get some error?

Please note the limitation with writing when using valuetype=bit:

Ok so not even the reading works…

Can you please try out with alternative client, e.g modpoll?

I have seen some issues with the library on windows so it might be that one as well…

Thanks, could you please make a Minimal config with single slave, matching the last query of modpoll? Please note that register 258 in modpoll corresponds to 257 in the binding.

Also please share all the logs with verbose level on pastebin.com. Now I see successful and error in the logs but do not know the general situation.

Sami

omar1971 · November 30, 2016, 10:24am

Sorry … I do not understand what evidence do I need to run.
What is pastebin.com?
you can tell me I’m new
what files you need?

ssalonen · November 30, 2016, 12:39pm

Hi

sorry for the unclear message

with minimal config I mean you have only one slave defined, corresponding to modpoll query, e.g.:

omar1971:

// query matching modpoll -b 19200 -p none -m rtu -a 1 -r 258 -c 2 -t 4:hex COM2
// modpoll's default stop bits is 1, and data bits 8 with rtu
// note that we use COM2 instead of your original config or COM8
modbus:serial.O1.connection=COM2:19200:8:none:1:rtu
modbus:serial.O1.id=1
// start 257 matches modpoll register 258
modbus:serial.O1.start=257
modbus:serial.O1.length=2
modbus:serial.O1.type=holding
modbus:serial.O1.valuetype=bit

and only one item

Switch O1_1 “O1_1_” (c_o) { modbus=“O1:0” }

Then configure verbose logging according the instructions in the wiki.

Then

clear existing logs
start openhab with start_debug
let it run for a while (e.g. 5 minutes)
upload log to pastebin.com, a website for copy-pasting text. It’s really easy to use, just paste the log to the text box, click “Create new paste”, and copy the URL here.

Best,
Sami

omar1971 · November 30, 2016, 8:36pm

Hello,
I tried to paste the contents of Openhab.log files (eg 3 minutes) in Pastebin.com site but it is too big.
How do I proceed
Thank you

ssalonen · November 30, 2016, 9:04pm

Hi

You can try to take the beginning of the log.

Pastebin.com should accept up to 0.5MB

configuration with a single word 257
and control of 4-bit switch.

Albeit very slowly, it works only bit 0 (controls the output and reports the status).
Bit 1-2-3 does not work

rossko57 · December 1, 2016, 12:00pm

You cannot simply change bits in a holding register. This is a limitation of Modbus. As far as the Openhab binding goes, it currently seems to try to write a single bit, but this results in bits above 0 being overwritten or blanked out.

I believe you will have to handle the whole register as a number item, and use rules to extract or set individual bits in that number at the Openhab end.

omar1971 · December 1, 2016, 1:46pm

can you help me.
I’m new with OpenHab and I do not know how to do.
Do you have any examples?
