Emerson Process Management now has a new class of smart instruments available that analyse the health of plant mechanical equipment and present actionable information to improve plant availability and performance. The CSI 9210 machinery health transmitter acquires vibration, temperature, motor flux, and machine speed on AC motor-pump machine trains, analyses the measured data, calculates machinery health, issues alerts if necessary, and recommends action to be taken.
Industry surveys indicate a strong demand for this type of online, field-based information. Typical process plants include 2500 machines, with 60% being motor-pump combinations. Additionally, mechanical failure is the cause of 43% of plant incidents. The new CSI 9210 Transmitter will significantly impact the way process industries use and maintain their rotating equipment, providing reliable information that enables them to get longer service from their equipment and initiate timely maintenance to prevent unexpected failures.
"The CSI 9210 Machinery Health Transmitter is a significant extension of Emerson's PlantWeb digital plant architecture and will deliver real business impact to users in terms of improved plant availability," said Craig Llewellyn, president of the asset optimisation division of Emerson. "Smart machinery health management delivers actionable information on rotating equipment health so plant personnel can prevent production upsets before they happen."
According to John Rezabek, controls specialist for BP Chemicals, Lima, Ohio, "The CSI 9210 Machinery Health Transmitter can alert our operators in real time when equipment problems start to manifest. If a change in upstream head, volatility, or composition results in increased flashing or cavitation, they can make adjustments to eliminate the problem."
The new device uses an embedded analysis engine to accurately identify potentially damaging conditions such as pump cavitation, bearing degradation, excessive synchronous vibration, and motor overloading and overheating. Results are communicated using the Foundation Fieldbus protocol into process automation systems and AMS Suite: Intelligent Device Manager predictive diagnostics software, giving users realtime access to the true condition of their motor-pump assets. With this realtime information, plant operators are able to easily view rotating equipment status, recognise issues with machinery, and take actions to improve availability and performance.
When used within the PlantWeb architecture, the CSI 9210 Transmitter delivers analysis results in the form of PlantWeb Alerts, which categorise the warnings as 'advisory,' 'maintenance,' or 'failed.' A specific Machinery Health Value is also given along with recommendations for any necessary actions. The assessment of machinery health generated by the CSI 9210 Transmitter gives plant personnel a better understanding of the condition of monitored equipment and problems that may be developing. This knowledge empowers the practice of predictive maintenance, resulting in less equipment downtime, longer machine life, and lower maintenance costs.
Why secure industrial communication depends on deployment as well
Fieldbus & Industrial Networking
The Industrial Security Harmonisation Group has released a joint industry perspective highlighting a critical truth in industrial cybersecurity: secure communication is not determined by protocols alone, but by how they are deployed and managed in real-world environments.

Feedforward control is a powerful technique that can dramatically improve control variance in cases where load changes cause big deviations from setpoint and the actual process dynamics are too slow to allow the feedback controller to operate fast enough to catch these disturbances.
