Industrial automation or numerical control is the use of control systems such as computers to control industrial machinery and processes, replacing human operators. Industrial Control Systems (ICS) are command and control networks and systems designed to support industrial processes. The largest subgroup of ICS is SCADA (Supervisory Control and Data Acquisition) systems. These are typically used in industries such as electrical, water, oil, gas and data. Based on data received from remote stations, automated or operator-driven supervisory commands can be pushed to remote station control devices, which are often referred to as field devices. Field devices control local operations such as opening and closing valves and breakers, collecting data from sensor systems, and monitoring the local environment for alarm conditions. Rapid Techs involved in manufacturing and sales of control devices and systems, factory automation systems and other electrical devices.
