Tunnelling OPC DA – Know Your Options

Anyone who has attempted to network OPC DA knows that it is challenging, at best. The networking protocol for OPC DA is DCOM, which was not designed for real-time data transfer or industrial systems. DCOM is difficult to configure, responds poorly to network breaks, and has serious security flaws. This article will look at how tunneling solves the issues associated with DCOM, and show you what to look for in a tunneling product for OPC.

Security for Industrial IoT

Remote data access is not new. However, several fundamental problems have arisen from a need to provide secure remote access to real-time systems on the Industrial IoT. Find out how Skkynet’s secure-by-design approach closes all firewalls and eliminates exposure to the Internet, IT networks, and plant networks–all with no VPN or additional hardware or software.

What is a Good Approach to Industrial SaaS?

From time to time, new industrial automation technologies come along that provide cost savings, better performance, and ease of use—new links for the chain. One of the latest of these is software as a service (SaaS), that provides access to hosted software over a network, typically the Internet, and is closely related to the concepts of smart factories, cloud computing, and the Industrial IoT. SaaS can open opportunities for industrial automation, but to be truly useful, it should be secure, quick, and robust, as well as adaptable and convenient to use.

Can I Store and Forward OPC Data?

It seems reasonable to ask if it is possible to store and forward OPC data. Nobody wants to lose their data if there is a network problem or the connection gets broken. A deeper understanding of OPC helps clarify what is necessary, and what is possible.
