This tender seeks information on proven technologies for re-engineering the OPC DA communication protocol, essential for control systems affected by Microsoft security updates. Solutions must ensure compatibility with existing DCOM-based infrastructures.
Eskom is requesting information on commercially available and proven technologies for the re-engineering of the OPC DA (Data Access) communication protocol. This initiative is crucial for control systems at Grootvlei Power Station that have been impacted by recent Microsoft security changes affecting Windows operating systems and DCOM-based communication infrastructures. The current OPC servers and Backup HMI have surpassed their planned replacement intervals, leading to reliability issues and potential operational risks. Vendors are invited to propose solutions that can effectively address these challenges, ensuring continued system functionality and compliance with updated security protocols.
The scope of this tender includes the assessment of technologies that can facilitate the upgrade of existing OPC servers and associated systems, including Backup HMI and engineering stations. Respondents should provide insights into their experience with similar projects, including references and indicative pricing. The successful implementation of these technologies is expected to enhance the reliability and availability of the control systems, thereby minimizing downtime and operational disruptions. Eskom aims to evaluate the proposed solutions to determine the best path forward for maintaining operational integrity at Grootvlei Power Station.
This tender is suitable for technology providers, engineering firms, and system integrators with expertise in OPC protocols, DCOM communication, and industrial control systems. Companies with a proven track record in similar projects are encouraged to apply.
