Create Modbus client via script

[AEK]

Code:

query = 'SELECT * FROM modbus_mapping'
counter = 0
for _, mapping in ipairs(db:getall(query)) do
  if mapping.bus_address == "" or  mapping.bus_address == nil then
    grp_address = '1/1/' .. counter
    if counter < 256 then
      dec_grp_address = knxlib.encodega(grp_address)
      address = grp.create({
      datatype = mapping.datatype,
      address = grp_address,
      name = mapping.name,
      comment = 'Auto mapped by script',
      units = mapping.units,
      tags = {},
      })
      counter = counter + 1
      db:update('modbus_mapping', { bus_address = dec_grp_address, bus_write = 1, value_delta = 0.1, value_custom = 'Auto mapped by script' }, { id = mapping.id })
    end
  end
end

Hi, Erwin!
Could you modify this script to create more then 256 objects at once?
I have profile with around 900 registers and it's not full
