2 byte error message

[admin]

It can also be done like this, but if you have several error messages the resulting string can be too large (string type is limited to 250 characters).

Code:

value = event.getvalue()

-- table key is bit number starting from 0
errors = {
  [0] = 'Stop & Go ratio ',
  [1] = 'Increased position travel ',
  [2] = 'Overload, reference position not attained ',
  [3] = 'No support at present',
  [8] = 'Connected actuator does not correspond to parameterised type',
  [9] = 'No communication possible at this address',
  [10] = 'Connected actuator signalling error, see Low-Byte',
  [11] = 'No valid Min / Max values',
  [12] = 'Non-Hall sensor motor actuators only: Actuator not yet synchronised',
  [13] = 'Test run active',
  [14] = 'Monitoring time of reference value elapsed',
}

result = {}

for i = 0, 15 do
  mask = bit.lshift(1, i)
  if bit.band(mask, value) ~= 0 then
    if errors[ i ] then
      table.insert(result, errors[ i ])
    end
  end
end

text = table.concat(result, '; ')
grp.update('1/1/1', text)

You can also make it multi-line by replacing '; ' in table.concat with '\n', but then you need some extra CSS:

Set "Additional classes" of your text object to "multiline" (without quotes) in Visualization editor.

Add to Custom CSS (Vis. graphics > Edit custom CSS)

.multiline {
white-space: pre;
text-align: left;
}
