SCADA Innovations

- Enhance our MySaS system using IEC-61850 Standard and add new features to it.
- Successfully managed to integrate a Modbus communication Protocol to our system.
- Successfully managed to make an engineering tool to convert a Modbus to MMS communication protocol (IEC 61850 standard) through MongoDB.
- Successfully managed to enhance my Engineering tool to create a CID file for any converted iec61850 electrical nodes from Modbus automatically and imported successfully that is why we will dispense with Sprechen and GE tools.
- Successfully managed to make a tool (iec61850 Server & Modbus Master) to be connected all times with any Serial Devices that support Modbus via specific serial port and get values from specific addresses from devices memories, after getting those values; I send them through what corresponds converted iec61850 nodes (from the CID file that I have created) for the client.
- Made a software tester for IEC 61850 using Maven Development and send many nodes at the same time using JavaFX.
- Upgraded many features of our used library to meet the project requirements. Write generic classes from scratch to parse/create any CID/SCD file to be used in the Tester and in the engineering tool that I made.
- Managed to open a connection for multi Servers at the same time to relate to a client using Virtual Network Interface and Network Programming.

R&D Software Engineer using Java

- I have worked as a Software Engineer at SCADA Innovations Company for SCADA systems. I have learned Java programming and OOP with Eclipse and Intellij, a good background in JavaFX, MongoDB, Morphia, MODBUS, and IEC61850 communication protocols, very good dealing with Linux OS.
- I used a program to make the connection between physical devices by ModBus communication protocol and made a GUI with JavaFX to complete this mission.
- I used a library named openiec61850 to make a connection between physical devices by iec61850 communication protocol.
- I write a program by Java to parse the CID/SCD file which contains all information of IEDs (Intelligent Electronic Devices) which has written by SCL language which based on XML and saves this info in CSV file and in the Mongo database using Morphia.
-  I still working to make a GUI tester for iec61850 to simulate the Server Models and send commands and values to IEDs
