Compartmentalization of Protocols in SCADA Communication

Abstract

In SCADA systems, Communication is very important. In communication, protocols are needed to be implemented to avoid some problems. In the current state of SCADA communication, two protocols are widely used, the T101 or IEC 60870-5-101 (IEC101) and the DNP3 (Distributed Network Protocol). In this paper, we present each protocol and discuss the specifications of T101 and DNP3. This can help SCADA operators to select which protocol is suited for the operations of their SCADA systems.
