John E.

I am a senior engineer with a decade of experience in mechanical engineering, mechanical design, and automation. I have an MEng in Mechanical Engineering, a PhD in materials engineering and I am a TUV registered functional safety engineer. I am also an IPENZ Chartered Engineer. My particular interests are safety integrated systems and automation of processes and production machinery. I am an expert in programming Siemens PLCs (S7-300 and S7-1200) and the full range of Siemens HMIs. I routinely use TIA V15 and Step 7 5.5 (classic). I have recently completed several SCADA projects using Inductive Automation Ignition v8.0. I have a great deal of experience in field bus protocols such as Modbus RTU, Modbus TCP, Profinet and Ethernet I/P. I have also installed many systems which log data from industrial equipment to mySQL and MSSQL databases. I have designed, installed and commissioned bespoke machinery ranging from Hydrogen production, to metal cutting, chemical processes and HVAC. I have experience of working on projects in North America, United Kingdom, New Zealand and Germany. I look forward to working with new clients.
