3. Hardy’s Solution – Meeting the Operation Outcomes
ROI - WHAT WAS THE “OPERATIONAL” VALUE ?
a) Reliability and lower life cycle costs. Accelerated ROI.
• Off the shelf components that are readily available and supported ongoing.
• Familiar components/technology that are well known.
• Component cost is considerably less than the current hardware components.
• Less dependence on vendor resources for upgrades, modifications, and troubleshooting.
• Components are robust and not subject to failure due to handling.
• Limited set of cost effective spares can be kept on-site
• Easier swap out of hardware
• Easier upload of software, configuration and calibration parameters dramatically reduces MTTR
(mean time to repair) in the event of a failure.
• Inter component communication via industry standard fieldbus protocols such as EthernetIP
• One HMI can display the production data for multiple rows
• The open platform allows for unlimited data collection and transfer to our MES system.
• Future loop control for weight control, and other controls enhancements are easily added.
• Depending on application: ROI can be reduced from years to months or months to weeks.
