Configured Process Control Systems for chemical processing plants for DOW Chemical. Worked in a team environment in conjunction with DOW to establish and document process control strategies.

Developed a dynamic general purpose Process Simulator (for control systems testing and operator training) to simulate real time input data to control systems based on its output data and process models. Written in C using Windows SDK, Win API and DDE local communication with PLC through VME bus backplane.

Reverse-engineered any brand of PLC software applications (A-B, Siemens, GE, TI, etc.) to the Ovation DCS format for Power Plant modernization projects. Implemented an Ethernet communication gateway to bridge EtherNet/IP field slave devices with a Modbus TCP master node.

Participated in the development of an Advanced Drilling Control System based on Siemens WinLC (Step7) soft PLC and Wonderware HMI. Configured WinLC and programmed in SCL and FBD. Implemented TCP Open Communications for PLC to PLC communication and MODBUS TCP for Remote I/O communications. Designed redundant star process control network using managed switches, fiber optics, isolators, gateways and media converters. Participated in various automation projects ranging from P&ID verification and Cause & Effect chart production to Allen-Bradley (A-B) ControlLogix and CompactLogix PLC programming, testing and documentation. Set up of Siemens WinCC HMI PLC tag import and communications.

Designed and implemented a process control system for a chemical in-line blender. After thorough process simulation using pumped water, the blender yielded less than 0.1% error per component. Designed, implemented and started up a process control system for a chemical reactor which included the control of oxide feed, and reactor temperature using two cascaded PID loops. Controls based on MTL MOST Hybrid Matrix Controller and SCADA System based on multiple Wonderware workstations communicating via MODBUS over Ethernet. Programmed in Function Block.

Developed control software for Cameron’s new BOP Control System based on Siemens Step7 PLCs, Wonderware HMIs, Profibus, Industrial Ethernet and OPC servers. Participated in the integration and commissioning of above systems for customer witness; that included networking, electrical, pneumatic, hydraulic and software troubleshooting.

Responsible for process control projects, which included system requirement specification, control panel design, PLC programming, HMI development, SCADA integration, testing, documentation, startup and customer service/support. Developed Valve Signature Analyzer on a Windows based PC using Visual Basic. The PC polled several GE PLCs using ActiveX controls and stored the data in a Microsoft Access Database using SQL. Implemented communication networks including Ethernet, A-B DH+, A-B Remote I/O, TIWAY, Genius LAN, RS-232 / 485 / 422 & Multiplexers. PLCs: A-B PLC-5, A-B SLC/500, TI-545, GE-90/30/70, MODICON; HMIs: Wonderware Intouch, TCP QuickPanel, PanelView, Nematron; Others: OMNI and Daniel 2500 Flow Computers and other MODBUS devices.

Participated in the design of Daniel Industries' next generation low-power Flow Computer / RTU (Ultra3000), including responsibility for the development of the data I/O subsystem, interprocessor communications, device drivers, boot-strap loaders, low-power control, etc. Analyzed and developed a highly-flexible, general-purpose operating system for oil & gas flow computers. Programmed in C, 8051 & Z80 Assembly, and LabVIEW for Windows.

Programmed Allen-Bradley (A-B) ControlLogix and CompactLogix PLCs, Siemens Step7 PLCs and PanelView HMIs for various applications. Performed PLC software updates and modifications to drilling tools in a team environment. Programmed in Siemens Step7 STL and SCL. Posted software applications to NOV’s PLM system. Developed a Pipeline SCADA System for The Valero Energy Co. based on GE Fanuc CIMPLICITY HMI. Programmed A-B CompactLogix PLCs. Established MODBUS communication links. Performed full performance tests on High Speed Turbo Rotating Machinery which involved VFD configuration. Designed control panels.
