Has anyone used/configured structured data logger(SDL)?
I am looking at using structurd data logger and was wondering if anyone has some tips or pointers. I have read the manaul and it seems straight forward, but there normally is something missed that they don't think of.
We have started upgrading a plant from Sattline that currently uses Journals and the new 800xA part is still writing to this but as we upgrade more we need to start writing to a database using SDL instead.
When I look at the service, I need to point at a database. Is this an SQL database that is used, and is it just the SQL software that comes with 800xA that is needed or do we need something extra?
Any information you may have will be very useful

The SATT journals mainly log process data and events. These functions are mostly replaced by the "Basic History" and "Alarm And Event" services in an 800xA system.
For production logging of Batch Reports, this functionality is done in the IMS (Information Management System) using "PDL" - Production Data Logging.Batch management and recipe management is done using the Batch Manager rather than the SATT line controllers.
This is not the only option of course, if you are looking at recording event based data into a third party reporting or historian system then there are several interfaces for 800xA that do not exist for SATT. These include OPC (Direct Access to Live Data) , OPC History (direct access to the history), OPC-AE ( access to the Alarm and Event messages) and ODBC.
SDL uses its own MSSQL datatabase. You can control whats logged but now how its logged (ie the data format and the fact thats its an MSSQL database only). The applications where I have seen it used are recording process data for ABB's paper machine optimisation software.
I'm currently working on a SATT system and have worked on 800xA systems that replaced SATT systems. 800xA data acess is obviously much more flexible than SATT journals and much more acessible, but your choice of which method to use depends on what sort of data you're collecting and what you want to do with it.
