With the booming development of computer and communication technologies, the application of the Internet of Things (IoT) is becoming more and more widespread, but the IoT system lacks unified standard and platform to standardize and unite, which causes a waste of resources. And, the IoT security problem is prominent and the information security is under great threat. In this paper, we propose a programmable IoT controller architecture, which is universal, standardized and secure. Under this architecture, users can write programs on the client side using programmable-logical-controller (PLC) programming language and send them to IoT controllers to achieve control requirements, and the status of IoT controllers can be monitored in real time. Different IoT controllers can also communicate with each other to realize the realtime migration function of the control system. The programmable IoT controller also incorporates information security prevention mechanism to improve information security. We implement the programmable IoT controller architecture concretely and conduct functional tests, and the test results show that the programmable IoT controller achieves the complete control requirements.
