Marion A. White, PE, Inc. (704.905.8901) is an industrial automation company providing systems integration, conversions, upgrades, documentation and customized training for Opto 22 Factory Floor and PAC systems. Marion A. White, PE, Inc. has roots in SCADA systems providing installed, converted, upgraded, documented and customized training for DMACS, FIX, FIX32 and iFIX Intellution and GE systems – since 1988.

Examples of our work include:
  • Power Generation Plant: Factory Floor modifications in Opto Control strategy, I/O hardware and Opto Display Windows. Created control room LAN to eliminate internet access to the Opto system, to provide local system backup location and to provide secondary location for historical data files.
  • ​Chemical company Reactor control: PAC system to new PAC system conversion plus additional control functions. Work included modifications to Opto Control Strategy, Opto Display Windows, I/O hardware and system tags.
  • Power Generation Plant: Factory Floor to PAC system conversion. Blended existing Factory Floor I/O with new PAC Ethernet connected I/O. Installed new PAC Controller, SB1 Brains and new PAC I/O. Added EB2 Brain with SCM Module for RTU communications. Added to and modified PAC Control strategy and PAC Display Windows. Also used Opto 22 PAC Manager to setup Controller and EB2 Brain. Consulting and assistance for OEM using PAC system for furnace control.
  • For power generation and Chemical plants: Created RMDS documentation system to mitigate liabilities related to staff personnel changes and to stop strategy modifications from being used as a troubleshooting tool. RMDS is also providing response to regulatory requirements.

Applications Experience

  • Industrial Automation: 27 years
  • Remote Monitoring: 27 years
  • Data Acquisition: 27 years
  • Machine 2 Machine: 5 years


Our company offers a unique and powerful Reliability & Maintenance Documentation System (RMDS). RMDS captures data circuit details including purpose, logic, tags, I/O hardware, wiring, terminations and power sources between HMI window objects and plant equipment at the end of the data circuits. RMDS captures staff knowledge and experience before they are lost to retirement or staff reductions. RMDS creation discovers incorrect configuration and RMDS helps to keep people out of the Opto 22 system.

RMDS mitigates liabilities caused by personnel changes and improves system reliability. It assists companies with regulatory and validation requirements. Tattered, marked up electrical drawings are no longer needed for maintenance and troubleshooting. Customers include: BASF, Corning, Duke, Hubbell, Glaxo, Land O’ Lakes, Loral, Mercedes, NASA, Nestle, Qualicaps, TriState Generation, Watson Pharma, Western Virginia Water Authority…..
