KNX 19.001 datatype

[KristianSl]

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-data...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 )

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)

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?

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

[zuuper]

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

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..

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