Benefits of Connecting a PLC to the Internet

PLCs have traditionally excelled at using wired inputs and outputs (I/O) to execute automation logic quickly and reliably. Now, users are recognizing the internet contains a wealth of information useful for PLC applications either directly in the logic or for operator displays. Many websites can programmatically deliver information such as weather forecasts, sunset/sunrise times or even commodity prices. With the right software tools built-in, modern PLCs can access this information.

Choosing the Right HMI

End users expect intuitive operator interfaces, and for industrial automation this means using touchscreen human-machine interfaces (HMIs). HMIs are valuable for complementing or superseding the capabilities of switches, buttons and lights in a control panel. The most reliable approach to choosing the right HMI is to examine the specific needs of the target application and work backwards to confirm all necessary options are available.

Pneumatics for Mechanical Motion

For equipment and machinery, fluid power is a term describing how mechanical motion can be achieved via hydraulics using incompressible liquids, or pneumatics using compressible gases like air or nitrogen. Pneumatics provides several advantages over hydraulics in many applications and has been a popular choice for industrial applications for over 100 years. Many consider compressed air a fourth utility after electricity, natural gas and water.

Bypass-Resistant Safety Devices Ensure Effective Machine Guarding

The most important machine design step is ensuring operator safety. During the design process, hazards are often identified that can be removed, but when a hazard cannot be removed, then various levels of safeguarding must be provided. These typically take the form of machine access guarding and point-of-operation guarding.
A best practice requires the selection of safety devices that are difficult to bypass. There have been many cases where guarding has been bypassed, often with disastrous results.
