This paper discusses to integrate existing industrial message protocol to real-time IoT platform with minor changes. MMS (Manufacturing Message Specification) is a message protocol for communication between heterogeneous devices in the industrial network. However, there is a disadvantage that a single message cannot control multiple devices and does not support devices using private IP. It is unsuitable for environments that currently use IoT of interest in industrial fields. In this paper, a method to use MMS in real-time IoT platform is discussed and proposed method is compared with MMS by implementing motor system.
