Programmable logic controllers provide automatic control of processes so that very little human intervention is required. Yet, this results in a well-coordinated, repetitive process.

These systems automatically start and shut down critical equipment in large and complex manufacturing processes. When in operation, programmable logic controllers ensure that all conditions are met before starting up a certain machine or process. In addition, the PLC continues monitoring the entire system using a variety of sensors.

Consequently, this ensures that everything runs as programmed. The PLC will trip if it detects a malfunction or abnormality in any of the monitored parameters.

The operating environment, size of the processes, ease of access by operators and maintenance personnel influence the choice of PLC.

A harsh environment with dust or small particles will require a PLC system with an appropriately IP rated enclosure. This prevents ingress of foreign particles into the system. The available space and layout also influence the choice. Therefore, most users require easy access for reprogramming, maintenance, or troubleshooting.

The simplest form of a PLC, all the basic components of a PLC include the I/O points, CPU, and software program. It is typically housed in a single enclosure. These PLCs are attached directly to the equipment being controlled.

Modular PLCs consists of several components on a common bus within a base unit to allow extending of the input and output. These units work on an expandable base unit. Therefore, it provides all the basic components of a PLC, i.e., a power supply, I/O points, memory and the CPU, and slots for additional cards.  These modules, which may be from the same or different manufacturers, are plugged together into a base unit.

This follows the same modular concept, but each of the modules plugs into a rack. The add-on modules are contained in racks which are then linked together through a network of connections. Since the rack mounting PLC is highly scalable, it allows very large systems to be assembled.

In energy management, the PLC monitors and controls equipment such as boiler systems. It helps the organization increase energy efficiency and safety. PLCs are also used in numerous everyday activities. They are found in factories, homes, commercial buildings, airports, unmanned car parks, and more.

The Hazards of Halloween Decor

When people talk about Halloween decorations, they’re often thinking about lots of lights combined with smoke machines, spiderwebs and paper decorations, all of which can be cheaply made. The down side of these homemade special effects is that many of these decorations are made of highly flammable material which, if left unattended and in close proximity to electrical lighting, can be anything but fun.

Another problem that often arises from Halloween decorating comes from using electrical lighting and components with electrical wiring that has become cracked and damaged over time. Any cracks in the insulation or damage to the wires can prove frightening and sometimes even deadly. Furthermore, heavy usage of lighting and decorations that require electricity can put a strain on extension cords, power strips and electrical outlets in your home, straining your home’s circuits.
