RTU/IED S. The comumer nub putaton a LAN consists of a Manter Computer anta 32 MODBUS RTU Series protocol between the Mester and the TrDs is provided using sub-station to measure electrical yuantities over an intertace system and ptores the as secn below. The master computer scans the teDo in every 2 minutes to colleet the measured values from the different point of sub-station. In a polling the master needs to collect there-phase currents and voltage measurgments. These measurements are located in a sequence of the memory space starting from [OEA as seen below. Every measurement has a word length of 16 -bit. (ivytes). a. Form the Modbus RTU Protocol frame structure of a request (Master co slave) for IED 1 having the address of [0001H] to read 3-phase voltages and currents. b. Form the Modbus RTU Protocol frame structure of the massage as the response (Slave to master message). c. Which polling/scanning method needs to be used? Why. Explain briefly. RTU/IED S.
