Abstract For industrial real-time controlling in IoT(Internet of-Things) environment, smart industrial controller can play a vital role in it. Nevertheless, in the IoT environment, each industrial controller is required to obtain the effective information from all kinds of sensors in real-time. The communication between the industrial controllers and the sensors should be lower time delay. Meanwhile, the software of industrial controller should make sure that each function module will be executed in time. To address these problems, this paper proposes a new design method of a mixed time-triggered and event-triggered industrial controller for industrial real-time control in IoT environment. This design adopts mixed time triggered and event triggered modes to manage multi-tasks, and utilizes RTX embedded operating system as the main scheduler. It provides an instance solution for industrial application. The performance of the proposed system was verified and achieved good effects in practical application of IoT for polycarboxylate superplasticizer manufacturing.
