This paper designs and implements an industrial Internet of Things (IIoT) platform based on the Manufacturing Message Specification (MMS) with enhanced security through unidirectional communications. For the proposed MMS-based IIoT platform, MMS over MQTT (MoM) protocol, which publishes and subscribes MMS messages using Message Queue Telemetry Transport (MQTT), is proposed along with a unidirectional data forwarding rule. In order to evaluate the performance of the proposed MMS-based IIoT platform, transmission time and packet loss rate are compared with User Datagram Protocol (UDP)-based communications. Through experiment and simulation results, we show that the proposed platform has a higher reliability of the data transmission.
