The vendor is required to provide a supervisory control and data acquisition (SCADA) system software that enhances reliability, performance, and security, provides a user-friendly interface, and reduces operational and support costs.
- SCADA system requirements:
- Software availability
• The software must be commercially available, off-the-shelf, and non-proprietary.
• It should allow independent systems integrators to manage configuration and maintenance.
- Mobile device compatibility
• The software must be html5-compliant, enabling remote monitoring and control via apple and android devices.
- Server and client compatibility
• Server software must be compatible with Microsoft windows server 2022 or later.
• Client software must support Microsoft windows 11 (64-bit) or later.
- Authentication
• The server must integrate with Microsoft active directory for authentication.
• It should support multiple levels of user access.
- OPC UA compliance
• The software must provide native support for OPC unified architecture (OPC UA).
- Virtual environment compatibility
• The SCADA server software should function seamlessly in a virtualized environment.
- Historian database compliance
• The historian database must support open database connectivity (odbc) compliance.
- City works/trimble unity compatibility
• The historian database and SCADA software must support seamless integration with the city works computerized maintenance management system (CMMS) for bidirectional data transfer.
- Historical data & graphical process displays
• The SCADA software should provide real-time and historical trend plotting within graphical displays, with the following features:
1. A minimum of 10 pens (tags) for both analog and digital values, including names and descriptions.
2. Options for analog pens to be displayed as layered or stacked plots.
3. A selectable time frame ranging from one second to five years.
4. Adjustable scaling for high/low values or graduated divisions.
5. The ability to display tag values at specific times based on cursor position.
6. Statistical data, including average, minimum, and maximum values for each plot.
7. Trend annotations, along with pause, zoom, and pan functionality.
8. Analog tag plot movement along the y-axis and an option to print displayed data.
9. Markers for alarm set points, displayed as continuous lines across plots.
10. Data export options in .csv format or direct export to a database for third-party software.
- Tabular data support
• The SCADA software should also include features for tabular data displays, including:
1. Support for an unlimited number of pens (tags) for analog and digital values, with names and descriptions.
2. A selectable time frame from one second to five years.
3. The ability to pause scrolling and view raw or summarized data with regular sampling periods.
4. Export options in .csv format or direct export to a database for use with third-party analysis software.
- Alarm and event management
• The software must align with ANSI/ISA 18.2-2009 standards for alarm management in process industries.
- Alarm management capabilities
• The SCADA system must include the following alarm management functions:
1. Lists for current, unacknowledged, disabled, active, configured historical, and shelved alarms/events.
2. Tools for searching and filtering alarms.
3. Annotation capabilities for alarms.
4. Individual or mass acknowledgment of alarms.
5. Adjustable font sizes for improved accessibility.
6. Priority representation through shapes, colors, and numeric indicators.
7. Data plotting for alarms, process display links, and audible alarm notifications with mute options.
8. Options for alarm shelving for a defined period, historical recording without acknowledgment, and alarm disabling.
9. A complete record of alarms and events, including timestamps, tag details, priority, status, and user acknowledgment.
- Remote alarm notification
• The system must support alert notifications via voice, text, and email.
- I/O drivers
• All input/output (I/O) drivers must support primary-to-secondary failover mode.
- External system connections
• The SCADA system must natively support connections to and from ancillary systems, including:
1. Hach water information management solution (WIMS)
2. Computerized maintenance management system (CMMS)
3. Laboratory information management system (LIMS)
- Contract Period/Term: 5 years
- Questions/Inquires Deadline: March 31, 2025
