KNX 19.001 datatype

[Daniel]

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)
