The Productivity Series of PLCs was designed with database connectivity in mind. The DataWorx Request (DWX) instruction helps you define all aspects of the connection to your DataWorx server, and even allows tags to be assigned for “in progress”, “complete”, “success”, “error”, “timeout”, and more. Define your own mapping table, 'where' table, and SQL View, and configure automatic polling with custom polling periods.
The Productivity Suite Software even comes with a trial version of DataWorx P3K (the software that runs on your server), so you can experiment with and test your database application with no risk (this trial version is fully functional, but the server will disconnect after 30 minutes). You can download the Dataworx P3K free trial separately here.
A single license (PC-DATP3K-1) for DataWorx P3K Server Software for Windows allows a single Productivity CPU to retrieve, add, delete and update data records in a standard database. Supports connection to a Microsoft Access, SQL Server or ODBC Servers.
An unlimited license (PC-DATP3K-UN) for DataWorx P3K Server Software for Windows allows an unlimited number of Productivity CPUs to retrieve, add, delete and update data records in a standard database. Supports connection to a Microsoft Access, SQL Server or ODBC Servers.
Both packages include both the 32-bit application software for Windows and the manual on CD-ROM. There is also an upgrade available from the single to the unlimited versions: PC-DATP3K-UPG - $500.00
