Communication is very important in SCADA systems. 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 system.

The Supervisory Control and Data Acquisition (SCADA) systems are gathering information or data from different sensors nodes sent in remote areas and after that transmitted to a focal controller which then oversees and controls this information. Wireless communications for Supervisory Control and Data Acquisition (SCADA) is obliged to applications where wired correspondences to the remote site are excessively extravagant or it is excessively lengthy, making it impossible to build wired interchang...
The Supervisory Control and Data Acquisition (SCADA) systems are collecting data from various sensors nodes deployed in remote locations and then transmitted to a central controller which then manages and controls this data. Wireless communications for SCADA is required to applications where wired communications to the remote site is too expensive or it is too time consuming to construct wired communications. Utilization of wired or line communications is becoming impractical as the scope is inc...
