Architecting thee Data Logging Infrastructure
A robutt data logging strategy requires more than simply connecting a sensor to a programmable logic controller (PLC). It demands a holistic view of the data controline, from the physical sensor te historian datase and thee edge or cloud layer.
The Sensor andControl Layer
Te quality of any trend analysis is directly dependent on thee quality of thee source data. Modern industrial sensing technology provides highly closate, high- frequency data streams, but signal integraty mutt bemaintained through proper shielding, grounding, and calibration. Old analogi signals (4- 20 mA) are excumentation supplemented or replaced by digital fieldbuses such as PROFINEtherNet / IP, and EtherCaT, which offer higher datea resolution and diagnostic capilities.
