Q: What was the primary motivation for the project?
Using the more user-friendly version 8, we wanted to add more detail on mimics and rely on more control functionality.
Q: What were the main goals established for the project?
The goal was to give the existing refrigeration personnel more advanced technology to monitor and control the 134 cold rooms on the primary site, as well as 2 remote sites:
• To effectively control the recipes for optimum fruit quality.
• To optimise the loading/unloading of rooms.
• Energy efficiency – load shedding according to the recipe of the CA condition
Q: In the procurement decision-making process what were the primary considerations that influenced the product selection?
Local support and the ability to maintain the system internally.
Licensing, maintenance and support
Q: What licences have been purchased for this particular application?
Q: How is after-sales support handled on this application?
No agreement in place – support as and when required.
Q: Do you have a documented process in place to manage, test and install OS and scada system software patches?
Integration, reporting and archiving
Q: Is the scada system integrated onto an intranet or the Internet?
No, it is a standalone system.
Q: Does the system include or interface with an expert system?
Q: Is the system integrated with an MES/ ERP or other management reporting or control system?
Q: Has any GIS (Geographic Information Systems) functionality been configured in the application?
Q: Has any asset management functionality been configured in the application?
Q: Does the application include data archiving/historian capabilities with an historical data reporting system?
Yes, standard Adroit data logging and SQL.
Maintenance, reliability and asset optimisation
Q: Have any operational or production benchmarking tools been configured as part of the scada system?
Q: What maintenance, reliability, asset optimisation or continuous improvement criteria were included in the user requirements specification for this project?
Mobile device support
Q: Are you currently using tablets, mobile phones or other smart mobile devices to interact with the scada system? If so, for what purposes?
Yes – standby personnel plus technical support for refrigeration personnel.
Q: Do you allow users to interface with the scada system via their own personal smart devices? (BYOD)
Yes – certain privileged users for daily duties and standby use.
Q: What was the predominant feature (or features) that made you decide to purchase this scada product over all others for this application?
Local support and ease of use.
Q: What was the most significant change that you implemented in scada engineering practice/technology in this project?
To go paperless through the use of technology.
Q: What single operational feature most impresses you about the product now that it is in operation?
Electrical and mechanical debugging of the refrigeration system through forensic investigation.
Q: What impresses you most about the architecture?
Marshall agent uses 1 tag that can scan 16 bits.
