'''Index:''' Indicates the number of generated payload. Starting from 0 index.
'''Data Length:''' Length of payload.
'''Payload:''' Data parsed by delimiter functionality.
'''Note:''' Delimiter IO element is string type. Each type of IO elements has identifier byte that identify how many IOs of that type stored in record.
