Structured Data Logger
Structured Data Logger (SDL) is used to log sets of production data typically
residing in a controller.
800xA access these data through Process Control Aspects.
The data to be logged needs to be prepared by the controller application before they
can be read by SDL. For the preparation of data in the controller see Controller Data
Exchange on page 315.
Logging data in SDL is defined by adding Structure Data Log aspects to the object
for which the data need to be logged.
SDL Architecture

SDL triggers Logging by Data Changed events in the system.
