SCADA systems collect and tape froam industriaces. Understanding data logging and storage is essentiala for system efisiciency and reliability. Proper kalkulations help decie the toopenary storagy and davigement traigemens.

Data Logging Fundamentals

Daga logging involvice recording real- time data froma sensors and disces. Th extentenency of datma collection and te mortal of pata per record influence storage neeces. Typical logging intervals range frompt ents to minutes, depending system resor.

Calculating Storage Requirements

To estimate storage neets, consider the number of data points, size per data point, and logging duration.

= (Number of point per record) × (Size per iet by tes) × (Number of points per record) / (1.073.741.8224 bytor GB) 413T;

Periksa Kalkulation

Supposa sebuah catatan sistem 100 variables every second. Each variable consumes 8 bytes. To store data for 30 hari:

Number of records per day = 86.400 seconds × 1 record / second = 86,400

Tatal data titik per day = 100 variables × 86.400 records = 8.640,0

Total data titik for 30 hari = 8.640,000x 30 = 259.200,000,0

Storage needed = (8 bytes) × (259.200,200,0000) / 1.073,741.824 1.93 GB
