System Requirements: - iOS 13.0 or higher Description: Locus Mobile for iOS works in conjunction with Locus’ environmental information management systems. The mobile application is used for simple and accurate data collection and upload from the field, and in the process improves workflow, enables productivity gains, ensures accuracy, and leverages location intelligence. Interaction with Locus Mobile does not require a real-time data connection, and content from the field is uploaded when it is convenient. Field users can work in remote locations with the assurance that all entries are saved and then synchronized back to a secure storage location once they are able to obtain Wi-Fi or cellular data service. Field data collection requirements and sophisticated data entry rules are configured from within Locus’ system and then assigned to field users and enforced through the mobile device. Field data entries are validated upon entry, and the user is provided with guidance on expected field measurement values. Once data are collected they are uploaded to the parent system for review, analysis, and reporting purposes, where they can also be easily audited for compliance support. Mobile users are presented with an interactive map interface that shows where sampling locations are and provides status information regarding the required data collection program. The interface supports ad hoc sampling activities that allow users to add sample locations and complete new data entry events. Locus Mobile application users can take advantage of the inherent location intelligence that has been built in: - The app is built around a map interface - Where do I need to go - Where have I been - Where am I now - Status of data collection/sampling is immediately evident using labeling and color coding - Add new locations on the fly – in the field (ad hoc) - Locations can be dragged/moved to refine placement - Delete and start again - Use satellite background images for improved context Locus Mobile can be used for processing field data collection operations for multiple users working within the same program. The system can be configured for a wide range of measurements related to well monitoring, air sampling and soil sampling. Locus Technologies clients are required to opt in to using the Locus Mobile application in conjunction with the client’s Locus environmental information management systems. Locus mobile users are required to obtain a user account from Locus Technologies in order to log into the Locus Mobile application. The app does not require users to submit payment for content or services within the app. Access and user accounts to the app are granted by Locus Technologies.

DeltaV Mobile provides smart notifications and context around abnormal process situations. For managers, engineers, and operators, it provides visibility into the process and alarm awareness, allowing users to monitor their operations on-demand with mobile views that are relevant to their specific needs. Unlike other mobile solutions for process monitoring or notifications, the tight integration with DeltaV enables you to leverage your existing DeltaV configurations to quickly find the data and alarms that you want to monitor, and to view the same real-time data, historical trends, and alarms that are displayed on a DeltaV operator workstation. All of this requires no additional DeltaV configuration. With DeltaV Mobile, users can easily have their operations data at their fingertips whenever they need it, allowing them to: •  Monitor personalized watch lists of process values, trends, and alarms that are smartly targeted to the right recipient •  View real-time data and trends from multiple systems (including non-DeltaV systems) with no custom engineering required •  Diagnose abnormal situations with context by viewing relevant process data with alarms •  Receive instant notifications for your most important alarms and process data via mobile push notifications, email, or SMS text •  Create and receive custom notifications for data from non-DeltaV systems or parameters that are not configured as DeltaV alarms •  Smart notification lists determine who receives notifications and in what order, escalated to the right person at the right time. •  Claim notifications in-app to stop the escalation chain and let other mobile users know that you’re aware of the issue. •  Chart improvements •  Tablet support
