November 2002 PLCs, DCSs & Controllers

In today's markets, manufacturing control systems do not only require scadas and PLCs to perform the control system functionality, they also require variable speed controllers to complete the overriding control system. PSY Systems caters for these projects using any one or all of these mentioned disciplines. Many projects fail or function poorly due to the lack of application engineering on drive systems. Typical mistakes are variable torque over speed, constant torque base speed mismatch and constant power winder control. Other problem areas are crane hoisting/inching and soft starter abuse.

As an ABB system integrator, PSY Systems specialises in ABB products and offers consultation, project management, project design, development, installation, commissioning and training on the following applications: fan/pump systems, conveyor systems, coiler/winder systems, mixer/crusher systems, crane/hoist systems, oven furnace systems, solid state and main frequency induction heating systems, gas/oil fired furnace systems.

The scope of service offered includes the refurbishment of old machine systems by replacing the part or the complete existing control system (especially in the case of DC machines), or supplying new control to greenfield projects.

Some of the industries serviced include iron and steel, food and beverage, milling, sugar, manufacturing, chemical, water and waste. PSY Systems is based in Johannesburg and offers its services nationally.

Deep learning based component inspection in the automotive industry
Beckhoff Automation PLCs, DCSs & Controllers
Achieving the shortest possible inspection times – even when working with different components – is paramount when it comes to series production. This is precisely what stoba Sondermaschinen achieved with its optical inspection system, which is based on deep learning, and features the Beckhoff XPlanar planar motor system at the conveyor system core.

Case history 189: Poor furnace temperature control.
Michael Brown Control Engineering Editor's Choice PLCs, DCSs & Controllers
Many process engineers do not appreciate the importance of flow loops in their unit controls. A senior process engineer once told me that flow loops need not be tuned well, as they generally have little effect on the more important and much slower loops like temperatures and pressures.

PLCs and PACs simplify data acquisition
PLCs, DCSs & Controllers
Data acquisition, data logging and data analysis are required functions for most modern industrial control systems. The simplest and lowest cost way to provide these functions is often by using the same platform that’s providing real-time control, namely the PLC or the programmable automation controller.
