Safe and efficient water and wastewater treatmentĭepending on the application, water needs to have different qualities to ensure the quality of finished products and the overall safety of production – and afterwards, it must be discharged safely.Ĭase History 183: Bad valve split-ranging causing problems Software-based solution protects plant uptime through redundant control operation using two standard industrial PCs. TwinCAT controller redundancy with standard hardware New hardware complements TwinCAT Vision softwareīeckhoff Vision offers machine builders and end users a complete image processing system that covers all the necessary components from software to lighting. PC- and EtherCAT-based control technology from Beckhoff uses industry and IT standards and components for cloud communication and big data. Optimised battery cell production with PC-based control Will the automation trend continue to accelerate? Infor’s Phil Lewis looks at some examples of smart, connected factories. Referro Systems managing director says there is a notable gap in the implementation of automation and control in the food and beverage industry.Īutomation makes the smart, connected factory possibleĪutomation is complex, especially in the manufacturing industry. Referro closes technology gap for smaller food and beverage plants This third and final article on the subject of the derivative term in digital controllers deals with choosing the right response if you wish the derivative action to work on both setpoint changes and load changes. System Integration & Control Systems Design Loop Signatures 15: Digital controllers – Part 7: The D term, concluded This is a wonderful example of how the use of a cascade flow control still allowed excellent control of the primary temperature control loop to be achieved, in spite of a valve with severe problems. Functionality includes the autotune facilities available along with overshoot inhibition (cutbacks), compensation for power fluctuations using power feedforward, linear, fan, oil and water cooling.įor more information contact Jerry Smits, Protea Automation Solutions, +27 (0), Credit(s)įurther reading: Control loop case history 185: Temperature cascade control on boiler desuperheaters.Įditor's Choice System Integration & Control Systems Design This control functionality utilises the advanced Eurotherm PID algorithm providing high performance and reliability to the process. The instrument can also provide two independent control loops (optional). An additional 14 virtual channels can be utilised to provide maths, counter, slave communications and totaliser functionality within the instrument. The four universal input channels provide high accuracy (suitable for use in Nadcap applications) and 125 ms parallel sampling. As well as multiple real-time views and historical review on the product, multiple data archiving strategies are provided utilising the 50 MB onboard flash memory, removable USB and data transfer via FTP to a specified server. The nanodac recording functionality utilises the secure strategies and UHH format developed by Eurotherm. The unit also provides user wiring from the front of the product for detailed configuration without the need to connect to a PC. Views include: horizontal and vertical trends horizontal and vertical bar graphs numeric alarm status and control loops. The 90 mm TFT display offers clear visualisation of process parameters with a wide selection of configurable views to best suit the application. This secure data recording device with accurate control is enhanced by a full colour, ¼ VGA display to bring a clear operator interface to the smallest machines. The compact ¼ DIN panel mount unit offers four high accuracy universal inputs for data recording and control. Eurotherm’s nanodac recorder/controller offers graphical recording combined with PID control.
