The paper presents the architecture of PLC CPU consisting of multiple cores enabling parallel processing of control algorithms. control programs consist of many program fragments that are suitable for parallel execution. Proposed architecture is constructed from independent logic and arithmetic units. They share common data memories of respective types. In order to enable tight coupling of processing a semaphored memory was proposed. This idea combines the memory with semaphore control. The data flow among processors is controlled by semaphored memory that is a part of global memory space. Correctness of the design was verified by FPGA implementation. Architecture is not intended for manual programming. A respective compiler has been developed that outlines are shortly given.

The trend of SCADA (Supervisory control And Data Acquisition) is to centralize more regional sites into one Main control Center (MCC), in order to increase the efficiency. Due to the geographical distribution of the sites locations, the most common communication method with MCC is GSM (Global System for Mobile Communication) network. Predicting network performance over a GSM network depends on the type of the transmitted data, the amount of data send, the transmission type (cyclic or event-based) as well as bandwidth and protocol characteristics. This paper presents a real-time comparison of the latency involved in the transmission of different loads of process data from a PLC (Programmable Logic controller) to the MCC, using the OPC (Open Platform Communications) protocol.

The exponential nature of the technological progress, along with the need for smaller and mobile computers led to the emergence of embedded devices like Raspberry Pi or Beaglebone Black. The main difficulty in using these embedded devices is that the device must be physically connected to a regular computer in order to be programmed to do useful work. This thesis presents a platform named Wyliodrin that solves this problem by allowing the programming of embedded devices directly from the Cloud.

As the Internet of Things evolves, many devices that were not previously considered suitable for this trend can now be used as a part of smart interconnected systems. This paper describes the process of adapting a Cisco IR829GW router to be used as both a Cisco IOS platform (for complex networking needs) and an embedded device running Yocto Linux distribution for Internet of Things application deployment and quick scripting needs using Wyliodrin.

The Internet of Things is a thriving field in which multiple open source tools are used. On the other hand, Windows 10 Iot Core, a closed source operating system designed with Internet of Things in mind, shows great potential. This paper presents the main platforms required for expanding open source development tools for this operating system, as well as the process of expanding an open source IDE to a Qualcomm board running Windows 10 IoT Core.

The paper presents an optimizing method of energy parameters of three-phase induction motor in order to improve their efficiency class from IE2 to 1E3 or IE4. These efficiency classes are defined in the European standard IEC 60034-301:2014. The optimization is performed using specific software by successively adjusting the geometry and the technology. The results have been validated by experiments within the UMEB SA laboratories. The three-phase induction motor that has been analyzed has a rated output of 45 kW, 380V (delta connection), rated speed 1475 rot/min and squirrel-cage rotor type.
