Description   Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices. Some human machine interfaces include knobs, levers, and controls. Others provide programmable function keys or a full key pad. Devices that include a processor or interface to personal computers (PCs) are also available. Many human machine interfaces include alphanumeric or graphic displays. For ease of use, these displays are often backlit or use...

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using human machine interfaces?
5 answers
Answers:
Always keep in mind the environment where your product will be used. Environmental issues are the number one cause of failure.
~Dave J, Marketing/Sales, Riverside, CA
See quality, versatile to different PLC, look for features like, sampling, recipe, alpha numeric sampling, alarm, tag
~Technical Support, Chennai, India
Try it before you buy it. It must make sense for the application. (Using a gaming control for movies is no good)
~Steven, Marketing/Sales, Dallas, TX
Stay up to date to better select and apply the best suiting model to the application.
~Luis B, Design Engineer, Guatemala, Guatemala
Correctly select the communication protocol and hardware aimed at connecting.
~Carlos D, Engineer, BS AS, Argentina

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of human machine interfaces?
