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.

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 product that tunnels OPC.

The Industrial IoT is different from the regular IoT. Mission-critical industrial systems are not like consumer or business IT applications. Performance is crucial. Most IT systems are built around a relational database, a repository of data that clients can add to or access, where a response time of a second or two is acceptable. IT data is typically sent across a network via HTML or XML, which adds complexity to the raw data, and consumes bandwidth. Although fine for office or home use, these technologies are not sufficient for the Industrial IoT.
