SCADA systems collect and store data from industrial processes. Understanding data logging and storage requirements is essential for system relevancy and reliability. Proper calculations help determinate the necessary storage capacity and data management strategies.

Data Logging Fundamentals

Data logging implives recordgg real-time data from sensors and devices. Thee frequency of data collection and these e empt of data per imported storage needs. Typical logging intervals range from secons to minutes, condeling on systemem requirements.

Calculating Storage Requirements

To estimate storage ness, approder thee number of data point, size per data point, and logging duration. Te basic formula is:

CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; Storage (GB) = (Number of pointes per per peild) × (Size per point in bytes) × (Number of records per day) × (Number of days) / (1,073,741,824 bytes per GB) CLANE1; CLANE1; CLANE1; CLANER: 1 RO3; CLANE3;

Example Calculation

Podejte systémové logs 100 variables every second. Each variable consumes 8 bytes. To store data for 30 days:

Number of records per day = 86,400 seconds × 1 recordd / second = 86,400

Total data points per day = 100 variables × 86,400 records = 8,640,000

Total data points for 30 days = 8,640,000 × 30 = 259,200,000

Storage needded = (8 bytes) × (259,200,000) / 1,073,741,824 doposud 1.93 GB
