David — Controls Engineer

PLC Programmer / Electrical Engineer Belcan / Innovative Controls Engineering, Lebanon, Ohio 6/2016 – 8/2016 (Summer Employment) Developed PLC systems by using both the Schneider Electric and Siemens brands of PLC devices. I have extensive working knowledge of using Vijeo 6.2 to develop all of the necessary HMI displays and activation buttons for human operator control. The development work with Schneider Electric systems also included Unity Pro, which allowed for the development of the actual Schneider Electric PLC devices themselves. I also have experience in using Siemens Step 7 development platform, including the use of WinCC for the development of HMI panels for Siemens devices. I have experience in programming the S-300 Siemens PLC system for the Ford transmission plant in Cincinnati, Ohio. I also have experience in using Fords new PLC development methodology referred to as FAST ( Ford And Siemens Transfer ) protocol that allowed me to make upgrades to various versions of Ford's assembly PLC/Robotic systems. These experiences were obtained in a three-month period to successful completion of projects. SQL / PYTHON / PLC Programmer / Electrical Engineer Aerotek / Schneider Electric, Oxford, Ohio 12/2012 – 5/2014 Developed Ladder Logic applications within the RSLogix5000 environment for the L33ER and the L35E Bradley PLC devices and Schneider Electric PLC devices for automation and retrieval of bar code scans and manufacturing automation. This also includes working with both Modbus serial communications technologies and CIP messaging routines. Developing also a ladder logic program using the socket network communications using CIP messaging for newer PLC devices (L33ER). CIP messaging also includes using CIP write and read data tables that were able to closely mimic socket network communications for older PLC devices such as the L35E PLC device. Also developments for CIP messaging were done using ODVA specifications and requirements. Translated legacy source code into Ladder Logic diagrams by using a static C source code analyzer or the Understand tool-set. I was also tasked with using the Perl language embedded within the Understand tool-set to refactor the Source code into a reduced logic representation of the legacy C/C++ automation source code. There was also some use of AUTOCAD during this endeavor to develop programming diagrams of the state machine representation for all programs developed for PLC devices. Developed software and embedded systems within a hand-held scanner based device to develop an automated system of scanning bar codes to be then sent to a legacy system known as the Quote-ToCash system that allows one to distribute strategic materials (Power Electronics) to their correct destinations. The SQL, Python, Java, and C# Programming languages were used in this project to automate the process of information being collected by a bar code scanning hand-held device, where said information would then be automated into a legacy system (Quote-To-Cash). The C# and C++ Qt programming were used to develop test prototypes for the GUIs operating on the handheld system. Used of both the WIN32 and MFC dynamic link libraries were required to handle the processing of automating information into the text-fields within the windows environment of the Quote-to-Cash system. Both dynamic link libraries were used within the python based program called Automa. The reason for the use of the automated approach of placing information into this legacy system was to eliminate any possibility of human error that could cause valuable power electronics equipment and other strategic materials from being sent to incorrect shipping locations. ADDITIONAL EXPERIENCE Embedded Software Engineer Consultant 10/2008 – Present Advanced Technologies and Resources (ATR), LLC, Springboro, Ohio Have acquired skills in developing Python and Bash script files for administration purposes for the website that is currently being constructed for ATR, llc. The Python scripting language is IPython. This version of python is needed for the development of administration management of websites and databases. It also allows for the rapid development of secure websites for business transactions. I am also developing skills with the use of python for instrumentation purposes and to interconnect to embedded and wireless systems. As such, I am using Python, IPython, Java and the BlueSpec SystemVerilog programming languages to develop an anti- malware program that will be developed on a concurrent processor within a Field Programmable Gate Array Device. The use of Python, IPython, and Java are being utilized in this endeavor to allow for internet connectivity. Django is also being evaluated to determine if a database can be formed on the internet that can connect to these antimalware processors to monitor, record, and evaluate internet or cyber-terrorist attacks. Developed Java script algorithms for the web-based monitoring designing phase of the creation of the Anti-Malware project. The use of the java programming language will allow simulated cyber-attacks on the internet. Developed a wireless RF linked MSP430-based device for Yellow Springs Incorporated (Xylem). This device was developed with the embedded C programming language within the IAR development environment for the MSP430. This MSP430-based device was designed for water metering of pollutants within the environment. The project regarding Yellow Springs Instruments lasted from 06/2010 – 01/2011. Use of C++ Qt programming was used for the development of the GUIs for interfacing with the instrumentation machines programmed with LABVIEW. Use of both the win32 and the MFC was required to develop C++ programs to operate within a graphical LABVIEW program called ORCA. Utilizing the ACL2 theorem and Spin model checker to develop formal VERIFIED AND VALIDATED algorithms for the Yellow Springs Instruments project. Embedded Software Engineer 3/2012 – 7/2012 Aerotek / Hobart Ground Power Systems, Dayton, Ohio Developed and evaluated software and electrical hardware for the 140 kVA Ground Power Unit for Hobart Brothers in Troy, Ohio. This unit is designed for avionics applications in powering aircraft while on the flight-line. This unit incorporates the Atmel microcontroller unit in controlling both the digital control outputs to engine/generator as well as the analog signals from said generator of the ground power unit. The use of J1939 or the CAN ( Controller Area Network ) was used to facilitate information between all Atmel ARM enabled processing boards for this system. Electrical Engineer / Software Developer 10/2007 – 10/2008 Belcan Corporation, Cincinnati, Ohio Developed multiple software products to assist in the release of the General Electric F-136 Engine for the Joint Strike Fighter Program.
