I need to add 20 PLC points to an existing Rockwell RSSQL 7 configuration to be logged and then I need to know how to retrieve this data using SQL commands (it will be via an ASP web page).
I can see where Data Points are added but it then seems you need to setup transactions that can either be OLE-DB or Compressed. Do I need to do this for each individual PLC point?
Am I best to create a new SQL table to hold my points? And is it possible to have multiple values per row in the table, e.g. 20 PLC values all against one timestamp?
Thanks.
