Rewrite by tag

[Stuart2000]

Is it possible to only rewrite value 3 if the value is 3?

I suppose you want to write back the same values to bus for certain tagged objects periodically. If so create a scheduled script and change the tag name as needed:

Code:

objects = grp.tag('my_tag_name')
for _, object in ipairs(objects) do
  object:write(object.value)
end
