Top Performance for Industrial IoT

/by

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.

Tunnelling OPC DA – Know Your Options

/by

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.
