dt.uint64

[manos@dynamitec]

This example writes a numeric value in double floating point format using raw datatype. If the resulting value is incorrect try removing the line with reverse() call.

Code:

val = 123456.67890

ffi = require('ffi')

dst = ffi.new('unsigned char[8]')
src = ffi.new('double[1]')

src[ 0 ] = tonumber(val) or 0

ffi.copy(dst, src, 8)

res = ffi.string(dst, 8)
res = res:reverse()

grp.write('2/2/2', res, dt.raw)

Thank you admin, it worked with reverse() call removed.

Now how can I use this script to be able to process a table?
I want to use the table from the original script because I have around 50 values to process.

Code:

if not values then
values = {
    { input = '32/1/24', output = '10/0/24' },
    { input = '32/1/25', output = '10/0/25' },
    { input = '32/1/26', output = '10/0/26' }
}
end


for _, value in ipairs(values) do
  Wh = grp.getvalue(value.input)
  kWh = tostring(Wh / 1000)
    grp.checkwrite(value.output, kWh)
end

How this would be then?
