Tech Tip: How PROFIBUS PA Profiles Work

Profile 3.0.2 defines the rules for PROFIBUS for Process Automation (PA). How can you use Profiles to your benefit in the Process Industry competition? Profiles were created to define properties and behaviors as an abstraction layer for devices, device families, or entire systems. Using Profiles gives the PROFIBUS or PROFINET devices a common framework for […]

IO-Link: Did You Know?

Did you know that the signal quality of measuring sensors can be increased with IO-Link? IO-Link enables reliable, loss-free signal transmission from the sensor to the controller. Background: When an analog signal is transmitted to the controller, several conversions from analog to digital and from digital to analog are necessary. Each of these conversions affects […]
