4. Asset Location
For organizations with large OT environments, it’s crucial to include the physical location of each asset. Whether the asset is located in the control room, production floor, or a remote location, knowing the asset placement allows teams to respond quickly to issues. It also helps streamline preventive maintenance activities and troubleshooting.
5. Asset Status
The status of each asset—whether it is active, inactive, under maintenance, or decommissioned—should be clearly documented. Monitoring asset status allows organizations to avoid asset downtime, schedule maintenance activities, and quickly identify assets that need attention. This also helps track the health of the asset, ensuring that no asset is left unattended when it needs repair or replacement.
6. Asset Lifecycle and Installation Date
Knowing the asset’s lifecycle is key for managing repairs and replacements. The installation date is an important factor in this, as it allows you to estimate the remaining useful life of the asset. When combined with maintenance records and warranty details, it provides valuable insights into the planning for asset replacement or upgrades.
7. Network Configuration and IP Address
For networked OT assets, recording the network configuration and IP address is critical. The network setup ensures proper connectivity across devices, enabling smooth communication between assets. It’s also important for securing the network and ensuring that the right security protocols are in place.
8. Maintenance and Service History
An OT asset inventory list should include a complete history of repairs, upgrades, and regular maintenance performed on each asset. Keeping track of the asset repair history and preventive maintenance helps prevent costly breakdowns and minimizes operational disruptions. It also helps teams spot patterns in failures, so they can take proactive steps to avoid future issues.
9. Warranty, Support Information, and Compliance
When tracking the warranty details for OT assets, businesses can ensure that they take full advantage of manufacturer support, reducing repair and replacement costs. Warranty details also help with managing the asset lifecycle and planning for the replacement of equipment as warranties expire.
