Not a lot of peoples understand exactly what Control Systems Engineering is. It’s a subset of Control Engineering, which encompasses any sort of technology where control is demanded. Simply speaking, taking a whole lot of inputs, performing calculations and setting outputs to cause the desired reaction is a management system – that is what control technology is all about.

Control systems technology, in its most frequent form, Mitsubishi plc involves the control of electric or powered machines or equipment with digital and analog signals from some sort of control device. This includes, but isn’t limited to Integrated Controllers, Programmable Logic Controllers (PLC) or Remote Terminal Units (RTU). The latter is used where there are lots of remote websites that report back to a Central Monitoring Facility (CMF).

A complete control system generally comprises the equipment itself, the digital control coating as described above and a software bundle which sits on a computer or otherwise, which allows individuals to interact with the gear.

This is usually referred to as a Human Machine Interface (HMI) or Supervisory Control and Data Acquisition System (SCADA). These systems are usually buttons, numerical setpoints and screens which permit the operator to see precisely what’s happening with the gear – including flaws, standing, flows, pressure, levels et cetera. This allows faster fault finding, diagnostics and basic information about the whole plant in 1 place.
