SCADA systems

SCADA systems gather real time data from around a working plant and then present that data to the operator on a screen in an easy-to-understand graphical format. As a turnkey supplier, O.Kay configures project-specific SCADA systems for recovery and processing systems of all sizes.

How does SCADA (Supervisory Control And Data Acquisition) work?

SCADA uses a PLC (Programmable Logic Controller) to gather the information from across the plant. The PLC is connected to the actuators and sensors of the plant and the date it collects is in the form of temperatures, pressures, speeds or statuses of the plant equipment such as machines and motors. Once gathered, the SCADA system presents this information in a meaningful, graphical fashion (mimic), which plant operators quickly recognise and understand.

Mimics can show the state of a motor, vent, valve, actuator, alarms or the fill level of a conveyor or the speed of a machine and allow the operator to change the status. For example if the operator needs to increase a conveyor belt speed, the system will have to increase the Hertz from the normal belt running current of 50Hz to, say, 60Hz. With a SCADA system the operator doesn't have to understand how this is being achieved, all he / she has to do is use the onscreen speed bar to increase the speed of the belt.

O.Kay SCADA systems provide the operator with a level of supervisory control whilst removing the complexity of how the activity occurs.

The advantages of O.Kay SCADA systems

MRFs for all throughput tonnages
SCADA takes a lot stress out of an operator’s day by sending live feedback from across the entire plant to a single screen/control point so he / she is fully informed without having to walk around the plant
SCADA reports any jams or malfunctions instantly and gives a pinpoint geographical location of the problem. This allows the operator to radio the engineering team with precise information and thereby bring about a much faster resolution to the problem
The information gathered by the SCADA system is presented to the operator in an easily-to-understand graphic of the actual plant. It shows machines operating normally in green; stopped machines in red etc. This allows the operator to understand the information the SCADA is reporting in a single glance
From a single location, the operator can start-up and shut down all machines, as well as control their speeds, by using the SCADA system
Touch screen monitors are available to make the controls even easier to operate
Screen allows operator to speed up or slow down machines from the control room
The SCADA control room is always located in the centre of the plant giving better vision for any supervisor positioned there
We create a clean office environment with optional air conditioning, heating, ventilation and dust control for the operator in the control room
We can integrate CCTV to run alongside the SCADA system with play-back monitors feeding into the control room also
