Our control systems include PLC & PC engineering & system integration, SCADA, energy management and safety systems. Automation solutions include special purpose machines, 3D modelling machine concepts, machine refurbishments, project management and maintenance & support. SCADA (supervisory control and data acquisition) is a flexible and powerful tool that can be used in almost any industrial monitoring and control system. The system collects data from various sensor points around a factory or plant and sends this data to a central computer which can remotely manage and control the data. The data can then be used in various ways, for example to correct any errors seen to be occurring in the process, to alter speeds of moving parts such as a conveyor, and perhaps more importantly detect a problem. The data collected can also be used to analyze production, check the status of any given piece of equipment, take readings and create graphs.
