Modbus, getting bits in a register

[admin]

You can use this helper function:

Code:

function getbit(value, nr)
  value = bit.rshift(value, nr)
  return bit.band(value, 1)
end

value = mb:readregisters(123)
if value then
  dampers_open = getbit(value, 0)
  fire_dampers_open = getbit(value, 1)
  ...
end
