SI Responses
Project details
Q: Approximately how many man-hours did the scada configuration take?
120 man-hours.
Q: What tools were used to minimise the man-hours taken?
Schneider Electric in-house tools were used to auto generate scada and PLC tag configurations for data pertaining to trends, alarms and interlocks.
Q: What human factors were taken into consideration in the HMI design process?
Schneider Electric configuration standards for the HMI cover colour and symbol usage. These were negotiated with the customer and documented within the Functional Design Specification.
Q: For the graphics development process did you use standard library images, or did you have to draw images from scratch?
All images were drawn from scratch. Standard libraries could not be used as the project required specific images be drawn to scale.
Q: How would you describe the library of graphic images?
Comprehensive.
Q: Did you use any ‘special’ images (e.g. photographs, 3D images, specialised dashboards, etc.)?
Yes, all the images were 3D.
Q: Did you use any video or multimedia technology in the application?
No.
Q: What alarm management standards or best practices were adopted in configuring the scada system alarms?
Alarms were categorised as Urgent (requiring operator intervention and acknowledgement), Warning (requiring operator acknowledgement) and Event (informational – requiring no operator action). In addition nine specific alarms are identified as critical IOG alarms (trigger an immediate SMS) and are shown on a dedicated HMI at the security desk.
Q: What structured processes were followed to determine expected performance under full load, and during abnormal failure conditions?
A complete library of test sheets exists within the Schneider Electric Quality Management System. During commissioning failures are simulated and results documented against the pre-determined set of acceptable limits. Exceptions are documented as non-conformances and actioned before final hand-over.
Q: What are the key physical communication layers and communication protocols employed in the system?
PLC communications – Modnet – copper and fibre; UPS and DC Plant – SNMP over Ethernet – copper; Air Handling Units – SNMP over Ethernet and Modbus RTU (Serial) to TCP/IP (Ethernet) – copper and fibre; Power Metering – OPC over Ethernet – copper
Q: What levels of redundancy are incorporated in this scada application?
Hot-standby redundant I/O-, Alarm-, Report- and Trend-servers have been implemented with full automated bumpless switchover. Redundant GSM modems.
