Re-engineering of OPC DA Communication Protocol

Balfour, Mpumalanga ESKOM
Open Closing: 6 Mar 2026 at 10:00 Published: 20 Feb 2026

Overview

Summary

This tender seeks information on proven technologies for re-engineering the OPC DA communication protocol affected by Microsoft security updates. Solutions must support systems with OPC classic architecture and DCOM-based communication.

Detailed Description

The South African government is requesting information on commercially available and proven technologies that can facilitate the re-engineering of the OPC Data Access (DA) communication protocol. This initiative is crucial for control systems that have been impacted by recent Microsoft security changes, particularly those operating on the Windows operating system and utilizing the OPC classic architecture based on DCOM communication. As many Original Equipment Manufacturers (OEMs) have exited the business and no longer provide support, the need for innovative solutions is paramount.

The scope of this tender includes identifying technologies that can effectively address the challenges posed by the security updates while ensuring compatibility with existing infrastructure. Interested parties should provide detailed information about their solutions, including technical specifications, implementation timelines, and any case studies or examples of successful deployments. The ultimate goal is to enhance the security and functionality of control systems that rely on OPC DA protocols, thereby ensuring operational continuity and compliance with updated security standards.

This tender presents an opportunity for technology providers specializing in industrial automation, cybersecurity, and communication protocols. By participating, businesses can contribute to the modernization of critical control systems and help mitigate risks associated with outdated communication technologies. The successful implementation of these solutions will not only improve system security but also enhance overall operational efficiency.

Suitable Businesses

This tender is suitable for technology firms, cybersecurity specialists, and engineering companies with expertise in industrial automation and communication protocols. Businesses that have experience in re-engineering legacy systems or providing innovative solutions to enhance system security will find this opportunity particularly relevant.
