The Internet of Things (IoT) is continuously growing and is now reaching into the industrial environment through new services such as remote maintenance for machine tools. Industrial applications of IoT require an increased awareness of security at all times. It is not only necessary that the data is exchanged securely; also the design of the hardware of the devices themselves needs to be considered. Security has to be designed right from the start into the IoT devices rather than added on later. This paper lays the foundation for the creation of a modular safe remote monitoring and maintenance system for machine tools through IoT devices at the hardware level. This article introduces a fully modular secure data acquisition system design approach with greater versatility, ready to be used in modern IoT manufacturing environments or for safe upgrading of existing legacy machinery.
