Tamper Resistant Recording in a PLC

Compliance with Regulatory and Quality Standards

Regulated industries typically require data recording formats that are resistant to tampering, and available for quality control and auditing at a later date. The E+PLC range utilizes several data management strategies that aid data integrity and file security.

Smart Efficient Data Management

Data files are stored in Eurotherm proprietary tamper resistant file format (.UHH), a better alternative compared to commonly used editable .CSV files. Process data such as operator logins, messages, alarms and other events can also be recorded for traceability.

Integrated recording functionality easily configurable in the CODESYS IDE
Data is recorded within a dedicated high availability file system on the E+PLC, reducing dependence upon communications to a Historian on a remote server
Data archiving is automatically restarted when communications are available
Tamper resistant backward compatible file format
‘Highly Reliable File System’ (HRFS) helps to prevent possible loss or corruption of data due to power interruptions
Traceability of what happened in the process and when
