Communication Protocols of Control System – Ryka Engineering Solutions In an operating plant, more the operating process data it gives better monitoring and control of the processes and lead indicators resulting into minimal downtime. This has a direct relation of production volumes and yields improved financial results. Providing this running plant parameter feedback is performed with different instruments working on different technologies. This instrument not only communicates the plant data to the central control system but also provides the self-health status data. The field of industrial communications is continuously developing at astonishing pace to cater the needs of industry. It is evolved from pneumatical to electrical communications.The technological developments have enabled this industry move from digital communication to a wireless mode of communications. This effort is towards addressing the communications and will briefly cover: Communication basics Serial communication and it’s basic standards Communication protocols: MODBUS HART DeviceNet ASIbus PROFIBUS FOUNDATION FIELDBUS Overall comparison of communication protocols Wireless network Engineering approach   Communication basics: Have you ever experienced communicating with a person who did not know your language without help of an interpreter? You must have experienced struggle to convey the message with some gestures, it must have created some funny situation. […]

Process experts recommend jacketed or traced pipelines based on fluid properties and site weather conditions. Here we are briefly addressing engineering guidelines for the instruments located on jacketed pipelines. To understand the instrument connections on jacketed pipelines, one need to understand jacketed piping systems- P&ID representation and required connections. General Introduction to Jacketed Piping Systems: Jacketed pipelines are generally used in process piping systems where solidification of process medium may occur or jacketing is used as an anti-frost measure as recommended by process experts. Jacketed pipelines helps to convey the complex process fluids (i.e. very viscous or likely to solidify) in an inner pipe, heated by steam / hot water/ hot oil or other heating medium between the jacket and the core pipe. Vacuum jacketing is also used as an insulator for cryogenic fluids. Generally outer jacket pipeline is one size higher than inner core pipeline upto certain line size. However, the project specific piping specifications for jacketed pipelines shall be referred for the details. There are two types of jacketed pipelines: Continuous / fully jacketed: All straight lengths, flanges, fittings, valves and branch connections are fully jacketed.The jacket is generally shown by box around the item in P&ID. There may […]
