10 Data logging
Removable SD card
An SD card is kept in the transmitter
Data is archived to the removable media automatically at set
intervals. Archiving continues until the removable media is full,
archiving then stops. To ensure all required data is archived
successfully, swap the SD card periodically for an empty one.
NOTICE
• Logging of data is possible only when an SD card is fitted
and online – in this state, Data and Events are lost.
• ABB’s DataManager Pro software can be used to store and
view data archived from the transmitter.
• A 2 GB SD card has sufficient external storage capacity
for >5 years data.
