Let’s open the week with a video for DeltaV distributed control system users on ways to integrate devices with Ethernet-based protocols into the DeltaV system. Examples of these devices include motor control centers, variable speed drives, programmable logic controllers (PLCs) and various types of online analyzers. In this 6:17 YouTube video, Emerson’s Rune Reppenhagen demonstrates […]
Smart field devices based on HART, Foundation fieldbus, and Profibus had standards-based files to integrate them with control and asset management systems. The file types, EDD and DTM were not compatible with one another causing process manufacturers and automation suppliers to grapple with both. Field Device Integration (FDI) provides a common approach for managing information […]
A ControlGlobal article, Industrial Networks: The Ethernet vs. Fieldbus Cage Match, spawned a discussion in the PROFIBUS and PROFINET LinkedIn group. I wanted to share Emerson’s Jonas Berge‘s posts on this topic: Wait! Are we talking about “H1 fieldbus” or “H2 fieldbus”? It makes a big difference. Personally I would say: Ethernet is slowly taking […]
Ever wonder why we have multiple forms of wireless communications on our PCs, smart phone, and tablet devices? 3G, 4G, 802.11, Bluetooth all serve a purpose in the types of information that is conveyed wirelessly between devices. For example, a Wi-Fi connection between your smart phone and home or office network provides higher bandwidth communications […]
