Subject: Synchronized SCADA control system
System construction: SCADA control system consists of 1 master station (controllogix 1756-L63) and 14 remote stations (Micrologix 1400).
System overview: The main target of this system is to compare instantaneous pressure transmitter readings at each remote station by transferring them synchronized to the master station.
System communication Network: cellular network.
System transmission protocol: DNP3 protocol using Prosoft Master/Slave interface module at master station (to act as DNP3 Master) and the Micrologix 1400 controller at each remote site (to act as DNP3 Slave).
Target: We want to ensure synchronization between pressure readings at Master Station to be able to compare instantaneous readings.
Question: Does the DNP3 Protocol guarantee this synchronization over cellular network? If yes, How come? If no, please advise suitable solution!
