KNX 19.001 datatype - KristianSl - 19.04.2019

Hi
I`m trying to write time and date to a group adress with datatype 19.001. Have been looking in the example: http://openrb.com/example-write-lm2-datatime-to-knx-group-addresses/
but can`t really see there how I`m supposed to Write the actually value to the Group adress. (I`m really new at this Undecided

)

Can you help me?

Use the code below and modify as needed

Code:
-- get current data as table

now = os.date('*t')

-- system week day starts from sunday, convert it to knx format

wday = now.wday == 1 and 7 or now.wday - 1

-- time table

time = {

day = wday,

hour = now.hour,

minute = now.min,

second = now.sec,

}

-- date table

date = {

day = now.day,

month = now.month,

year = now.year,

}

--- full date bits

OCT08 = now.year - 1900 

OCT07 = now.month

OCT06 = now.day

OCT05 = bit.bor(bit.lshift(wday, 5), now.hour)

OCT04 = now.min

OCT03 = now.sec

OCT02 = 0 -- subfields like working day and dst not specified in this sample

OCT01 = 0 -- subfields like quality of clock not specified in this sample 

-- write to bus

date_time = string.char(OCT08) .. string.char(OCT07) .. string.char(OCT06) .. string.char(OCT05) .. string.char(OCT04) .. string.char(OCT03)  .. string.char(OCT02)  .. string.char(OCT01)

grp.write('Date', date, dt.date)

grp.write('Time', time, dt.time)

grp.write('DateTime', date_time)

RE: KNX 19.001 datatype - zuuper - 19.12.2019

ello,

It doesn't work for me when I have to write down a datetime (DPT 19.001).

I only get the result:
RawDpValue
00 00 00 00 00 00 00 00

Can anyone try to help me please?

My code is,
function setDateTime(obj)

-- get current data as table
now = os.date('*t')

-- system week day starts from sunday, convert it to knx format
wday = now.wday == 1 and 7 or now.wday - 1

-- time table
time = {
day = wday,
hour = now.hour,
minute = now.min,
second = now.sec,
}

-- date table
date = {
day = now.day,
month = now.month,
year = now.year,
}

--- full date bits
OCT08 = now.year - 1900
OCT07 = now.month
OCT06 = now.day
OCT05 = bit.bor(bit.lshift(wday, 5), now.hour)
OCT04 = now.min
OCT03 = now.sec
OCT02 = 0 -- subfields like working day and dst not specified in this sample
OCT01 = 0 -- subfields like quality of clock not specified in this sample

log (OCT08,OCT07,OCT06,OCT05,OCT04,OCT03,OCT02,OCT01)

-- write to bus
date_time = string.char(OCT08) .. string.char(OCT07) .. string.char(OCT06) .. string.char(OCT05) .. string.char(OCT04) .. string.char(OCT03) .. string.char(OCT02) .. string.char(OCT01)
grp.write(obj, date_time)

end

Hi
I used your script without the function and it works.

Code:
  -- get current data as table

  now = os.date('*t')

  -- system week day starts from sunday, convert it to knx format

  wday = now.wday == 1 and 7 or now.wday - 1

-- time table

  time = {

  day = wday,

  hour = now.hour,

  minute = now.min,

  second = now.sec,

  }

  -- date table

  date = {

  day = now.day,

  month = now.month,

  year = now.year,

  }

  --- full date bits

  OCT08 = now.year - 1900

  OCT07 = now.month

  OCT06 = now.day

  OCT05 = bit.bor(bit.lshift(wday, 5), now.hour)

  OCT04 = now.min

  OCT03 = now.sec

  OCT02 = 0 -- subfields like working day and dst not specified in this sample

  OCT01 = 0 -- subfields like quality of clock not specified in this sample

  log (OCT08,OCT07,OCT06,OCT05,OCT04,OCT03,OCT02,OCT01)

  -- write to bus

  date_time = string.char(OCT08) .. string.char(OCT07) .. string.char(OCT06) .. string.char(OCT05) .. string.char(OCT04) .. string.char(OCT03)  .. string.char(OCT02)  .. string.char(OCT01)

grp.write('date test2', date_time)

Can it be a problem because my language-settings Swedish?

RE: KNX 19.001 datatype - admin - 19.12.2019

Try specifying datatype explicitly:
grp.write(obj, date_time, dt.string)

(19.12.2019, 14:55)admin Wrote: Try specifying datatype explicitly:

When I specify with dt.string, the result been type of
16.001 Character String (ISO 8859-1)

And nothing saves/writes into '2/0/0'

Hi,

You should use the 250 byte object for this..

BR,

The object you writing to must be 250 byte string. The real values you will see only in ETS group monitor
