To streamline and facilitate its performance, Industrial Olechemical Products (IOP) has implemented an Adroit scada system at Durban Harbour. IOP now operate seven storage tanks, which serve as holding cells for inbound plant oil on the Adroit scada system. From this point of entry, IOP truck the oil to various other sites. IOP's engineers and managers needed to source a scada system which would fulfil their monitoring and control needs, while allowing them mobility and scalability.
The Adroit system offered IOP the ability to monitor tank levels and gives them the on/off switching capacity to allow the transfer of oil between tanks. This ability is also critical in the transfer of plant oil to trucks for freighting too other destinations.
IOP management required an SMS warning system that would notify them if tank levels changed while no one was onsite. Systems integrator, Protemp, was able to implement this facility using the Adroit SMS drivers which are built into the system. The Adroit advantage further provides a structure for configuring alarms that allows for intelligent alarming practices, thereby eliminating over-alarming of systems, which otherwise would ultimately lead to the operators ignoring the meaningless flood of alarms.
The Adroit facilities allow reporting in an Excel format which IOP use to monitor the in/out levels per oil transfer as well as the time taken in order to maximise its business management and reporting. Using Adroit, IOP is capacitated for logging and trending the levels and activities of each onsite tank.
Easy-to-use Wizards allowed Protemp programmer, Dewald Bezuidenhout, to customise intuitive graphics for the system which is currently running on Windows 98 at Jacobs and Windows 2000 at Island View. The highly effective graphics were achieved with minimal programming effort and are a standard feature with the Adroit system. The integration of the systems was made possible by using PC Anywhere. Bezuidenhout comments, "Adroit is a benchmark product in terms of its user friendly interface and for its ease of use, it is not script intensive as many other scada packages are."
The system is running in conjunction with a Moller Electric PLC gathering the information that the system requires. Protemp is using a Sucom A driver provided by Adroit which allows the PLC and scada systems to communicate.
Temperature probes in the tanks factor the temperature and the level of liquid that is used to calculate the tonnage of the product. It then reports this information in the form of various windows. Future expansion of the system will include remote user dial-in from Jacobs to Island View made possible by PC Anywhere.
