VAV Optimiser, Max Function

[admin]

Fault objects should have similar names to the value objects that you are using for calculation. You need to change the "search_for" and "replace_with" parameters in gsub so the value object name is converted to the fault object name.

Code:

function tag_max(tag)
  local objects = grp.tag(tag)
  local result = -math.huge

  for _, object in ipairs(objects) do
    local faultname = obj.name:gsub('search_for', 'replace_with')
    local faultobj = grp.find(faultname)
    local fault = false

    if faultobj then
      fault = faultobj.value
    end

    if not fault then
      result = math.max(result, object.value)
    end
  end

  return result
end
max = tag_max('MaxExtDmpPos')
log(max)

grp.checkwrite('32/1/23', max)
