Request for Information on Commercially Available And/or Proven Technology for Re-engineering of the Opc Da Communication Protocol for Control Systems

ESKOM is seeking information on commercially available or proven technologies to re-engineer the OPC DA (Data Access) communication protocol. This initiative addresses control systems impacted by Microsoft security changes on Windows operating systems, specifically targeting those with an OPC classic architecture infrastructure based on DCOM communication, where original equipment manufacturer (OEM) support is no longer available due to business exit.Specific eligibility criteria are not detailed in the provided information. However, respondents should possess expertise in control systems, OPC DA communication protocols, DCOM-based architectures, and solutions for mitigating security impacts on legacy systems. Experience with re-engineering communication protocols and adapting to evolving operating system security requirements is crucial.
