Codes and regulations: Electrical Controls’ Dirty Little Secret: We Don’t Follow NFPA Rules - Take the survey! Of course safety is important, but most don’t follow NFPA 70e safety rules for working on an energized electrical panel. Risky? Yes. Unsafe? No, according to this system integrator. Perhaps industrial control panels need their own arc flash standard. (Do you follow the rules when working on control panels? Link to anonymous survey. See related articles.)

IO Module Replacement: What You Need to Know – When upgrading processors, do I/O modules also need replacing? Many processor brands will communicate with legacy I/O systems and provide most or all functionality of modern control platforms. This may not be the case if changing processor brands, according to this system integrator.

Before: Old control panels make troubleshooting and maintenance very difficult and time-consuming, in addition to posing problems with downtime and potential safety issues. Shown is an old control panel with dated hardware and hardwired pneumatic solenoid

Coriolis flowmeters continue to gain market share - About to displace magnetic flowmeters, Coriolis designs are poised to move into the number-two spot. Continuing growth says number-one is inevitable.

 

When your parts supply for an old system runs out - Providing geriatric care for an aging control system or piece of critical equipment can require you to be creative when your parts supply dries up. There are alternatives.

 

Disturbance-Rejection vs. Setpoint-Tracking Controllers - Designing a feedback control loop starts with understanding its objective as well as the process’s behavior.

Design trends in PLC-based control systems – Advances in electronics manufacturing are supporting higher functionality levels in industrial automation hardware.
