Use a scheduled script:

Code:

key = 'modbus_error_time'
time = storage.get(key, 0)

items = db:getall([[
  SELECT *
  FROM modbus_errors
  WHERE errortime>?
  ORDER BY errortime
]], time)

if #items == 0 then
  return
end

texts = {}

for _, item in ipairs(items) do
  time = item.errortime
  date = os.date('%c', time)
  texts[ #texts + 1 ] = date .. ' - ' .. item.errortext
end

message = table.concat(texts, '\n')
mail('user@example.com', 'Modbus errors', message)

storage.set(key, time)
