Data Managers & Data Loggers

Data Managers & Data Loggers

Data managers and data loggers are paperless recorders and organizing platforms that collect process values from analog and digital inputs, present them clearly, and archive them securely for later review. Positioned between field instrumentation and higher-level automation layers, they provide a reliable “system memory” for what actually occurred in the process - independent of transient controller trends or temporary screen views.

A data logger focuses on straightforward indication and storage of measured values, while a data manager adds broader I/O capability, richer visualization, and more advanced functions such as limit monitoring and analysis. Application packages extend the base device into defined use cases - such as energy, batch, or wastewater - by adding calculations, templates, and reporting logic that align the recorded data to the decision points that matter.

Key benefits include higher process transparency, higher product safety, and a high degree of data security through structured logging and secure archiving. Because recording is paperless (no pens, charts, or mechanical wear items), routine upkeep is reduced while record continuity improves. Where supported, an integrated web server provides remote access to operation and visualization, lowering maintenance effort and accelerating diagnostics.

Integration is typically achieved through common industrial communication protocols so measured and calculated values can be transferred to superior systems and plant modules can be interconnected. Support for widely used fieldbuses - such as Modbus, Profibus DP, PROFINET, and EtherNet/IP - simplifies adoption across heterogeneous architectures. Installation options (field, panel, and Ex-area variants) allow the recording layer to align with area classification and cabinet standards.

Typical applications include paperless recording of critical unit operations, compliance-focused documentation of regulated steps, utilities and steam system monitoring, and capturing transient excursions that are easy to miss in standard control-system trending. They are also effective as standalone “black box” recorders on packaged equipment and remote skids where local visualization and robust long-term logging are required.
