For the completion of the development of the SGCS Software application a server was installed and operated (at Pisga lab Israel). It demonstrates a two way Communication over the internet between the Central application and a field RTU / Gateway (at Energy Team Italy).
RTU: Each RTU communicates with the server in TCP/IP encapsulated MQTT Protocol. The RTU will always be in Client mode and will connect in a fixed Interval time.
CS : The communication server is handling the traffic between SGCS and RTU’s. On incoming messages the CS is checking only the general message format and sends the appropriate ACK to the sending RTU. The database Layout is described below but for this level there will be two tables: Received data and to send data. These tables will allow the Async processes to work in different levels of autonomy.
RMBL : This Module is responsible of handling each message received into the system. Messages that are not recognized as genuine will be marked for further analysis. Genuine messages are decrypted, moved to a history table and update the specific data.
OUTBL: This module is responsible to analyze the current status of the grid and generate requests to the RTU’s in accordance with the Business Module algorithm (This algoritem will be provided by LEI).
AP: The administration/ configuration portal is the module that is used to administer all the system parameters and the entities conforming the grid.
