The central controller (PLC) and remote data acquisition device (Remote I/O) in the model are designed based on a modular structure, that allows flexible execution of various problems without causing changes too large on the hardware structure of the system. The flexible system scalability facilitates the development of practical content for different modules in the training program, as well as serves as a foundation for the implementation of further studies. Currently, based on the hardware model, there are 09 practical exercises were built to meet the requirements of providing knowledge and skills in connection, programming, control, monitoring and operation of distributed control systems. Experimental results on the model show that the system works well, the problem of data collection, processing and communication between the PLC controller - ET200SP - the board status LED system is done quickly and accurately.
