TNB M10x – In-house Developed Tool for Learning IEC 60870-5-101/104 SCADA Communication Protocols

Abstract

TNB Grid Division (TNB Grid) and Distribution Network Division (TNB DN) utilize Supervisory Control and Data Acquisition (SCADA) systems to manage the power grid and the power distribution networks respectively. To ensure the relevant TNB personnel is highly competent in SCADA-related subjects, TNB Integrated Learning Solution (ILSAS) has been providing the IEC 60870-5-101 SCADA communication protocol training for the past 10 years. In 2018, the training module was enhanced to support the IEC 60870-5-104 topic in line with the recent adoption of the protocol in both TNB Grid and TNB DN. Although commercial simulation software packages are available as tools to assist in learning the IEC 60870-5-101/104 protocols, they represent CAPEX investment to these divisions. As a strategic initiative to reduce cost on acquiring those tools, TNB Grid has developed the M10x software as an alternative to the various commercial tools with similar or better features. This paper provides an overview of the IEC 60870-5-101/104 training module and how M10x is used as part of the module. A brief description of the software's main features and comparison with a selected commercial tool are also provided.
