Once connected, MPulse captures SCADA measurements, allowing users to define the types of data to collect, the assets to monitor, and the frequency of data collection.
Enhancing Maintenance with Condition-Based Strategies
SCADA and CMMS integration empowers maintenance and reliability teams to implement condition-based maintenance (CBM). CBM focuses on performing maintenance based on the actual condition and usage of assets—such as temperature or run hours—rather than relying on scheduled intervals. This proactive approach ensures maintenance is conducted only when necessary, optimizing asset performance and extending lifespan.
The Pitfalls of Other Maintenance Strategies:
- Reactive Maintenance: Performed in response to unexpected failures, reactive maintenance often comes too late to prevent significant damage or downtime.
- Preventive Maintenance: Based on arbitrary time schedules, preventive maintenance can lead to either under-maintenance (causing failures) or over-maintenance (wasting resources, time, and labor).
With condition-based maintenance powered by SCADA and CMMS integration, maintenance is performed at the optimal time, based on real-time asset data. For example, when a motor exceeds its normal operating temperature, the SCADA system triggers an alarm. This alarm then sends a signal to MPulse, which automatically generates a work order, ensuring timely maintenance to prevent potential issues.
Real-Time Alerts and Automated Work Orders
MPulse’s integration with SCADA systems allows maintenance teams to set up automated condition-based work orders triggered by specific alarms or data thresholds. If an asset’s performance falls outside of set parameters, such as abnormal temperature readings or excessive vibration, MPulse generates a work order automatically, ensuring the necessary action is taken before a failure occurs.
The Benefits of SCADA-CMMS Integration
By connecting your CMMS to your SCADA system, maintenance and reliability teams gain access to invaluable real-time data that enhances decision-making and resource allocation. This integration helps to maximize uptime, improve asset reliability, and optimize production processes, ultimately driving greater operational efficiency and profitability.
Incorporating SCADA into your CMMS workflow allows your organization to implement condition-based maintenance strategies that are more precise, effective, and resource-efficient than traditional preventive or reactive approaches.
