Using
Multiple Sockets to overcome Digi Lockup

and continue.
Our observation was that the product
could no longer open the socket and would lose any ability to communicate with
the Digi using that socket.

Using flexs2db to Manage Database Size
While doing FactoryLink support, CTH
determined that it would be handy to have a tool to create the appropriate
database tables and related indexes for certain tasks such as trending and AGA

are required. It would not require knowledge of SQL server management or tools,
hence abstracting that away from the end user.
It was also determined that customers
were running into database size issues with SQL Server and/or the filesystem
who did not have a SQL person handy, and so a data deletion feature was added. Read More...
