Profibus health check now available from ABB Measurement & Analytics Service

October 5, 2015

Pbus hcheck

A Profibus health check carried out by ABB is now available to industrial plants keen to operate their plants efficiently and maximise their up time.

The evolution from the days of 4 to 20 mA output communications to intelligent Fieldbus analysers may mean more diagnostic data is transmitted, but in order to ensure the data is reliable a new type of engineer with Profibus certification is required. Not only is this training expensive, but the engineer must have capabilities across all slave devices such as instruments, motors and drives to effectively analyse the performance of the Profibus network and the speed of its communications between the instruments and the master, the Gateway operating system.

Furthermore, purchasing test equipment is costly where many plants may have a limited budget.

ABB’s current knowledge and experience of instrumentation is well placed to bridge the gap between plant instrument engineers and system engineers, so that all plant or process measurement data is available. As part of the service, a comprehensive report including a list of devices on the network, signal waveforms, recommendations and findings, will be generated to confirm the Profibus network’s current performance. Testing equipment is provided by ABB too, so that plants need not purchase it to be used once and left in storage.

One example of the benefits of this service can be found at Imperial College London’s carbon capture plant where ABB Service Engineer Paul Bick connected a Profibus analyser to the plant’s communication system. The results revealed that the optimum speed for performance was 1500kb/second rather than its previous speed of 500kb/second, and increasing the speed to the new limit immediately produced a significant increase in response time from the instruments.

The Profibus health check also includes a review of the installation method. The Profibus Installation Guideline document refers to maximum cable lengths and cable segregation. During his service at Imperial College Paul Bick established that the cables were too short. The university quickly removed the risk of issues with reflections, data corruptions and interferences, by following his advice to extend them.

As standard, service highlights also include rectifying faulty instruments so that both the network and instruments perform to specification.

It is recommended that a plant carries out a Profibus health check whenever issues have been experienced as the reliability and health of the communications network is fundamental to any plant’s performance.

Dave Head, Service Product Manager for ABB Measurement & Analytics explains, “This service provides peace of mind by ensuring customers’ Profibus networks are optimised for best performance. ABB’s Profibus certified engineers fill the gap between the instrument engineers and system engineers which are currently lacking in most operations. This provides value to customers as ABB can offer support across the measurement network.”

ABB launches new flow calibration and valve testing guides

April 26, 2015

ABB’s Measurement and Analytics business has launched two new guides covering its services for flow calibration and valve testing. Available on request from abb.service@gb.abb.com, the guides explain how ABB’s flow calibration facilities at its Stone house and Workington factories can be used to help check the accuracy of flowmeters and control valves.

For flow calibration, the facilities enable a wide variety of flowmeter types to be calibrated to the leading international standards. All calibrations are carried out to ISO9000, with the option of a UKAS accredited calibration where the certificate carries the ILAC and UKAS Calibration Laboratory 0255 logo.

The flow calibration guide explains how the facilities can be used to calibrate meter sizes from 1mm to 2.4 metres at accuracies down to ±0.1%. It also covers the range of calibration techniques available, including gravimetric, volumetric or comparison methods, describing each technique and explaining how to choose the right method.

The valve testing guide covers ABB’s ability to test control valves from 25mm up to six metres and weighing up to 10 tonnes in accordance with the EN ISO 60534-2-3 standard for control valve testing.

The guide outlines the testing process and discusses the benefits of ABB’s service, which enables valve users to ensure that their valves have been tested for their specific requirements. Both services are offered via ABB’s Measurement & Analytics Products Service team and are part of a wider service capability spanning ABB’s entire portfolio of instruments and analysers.

The vital role performed by flowmeters, control valves or any form of instrument or analyser means that it is worth investing the money, time and effort in ensuring that devices are properly serviced throughout their lifetime, from installation and commissioning through to upgrade or replacement.

Our flowmeter calibration and valve testing services are just two examples of our wider service offering, which can help our customers to enjoy continued accuracy and high performance from their equipment throughout its operational life.

To request a copy of the guides, or for more information about ABB’s instrument and analyser service offering, please email abb.service@gb.abb.com or call 03339 997 996, ref. ‘Guides’.
