We know you demand more than just dropping it in a CSV file

Everything in OPC Data Logger came from watching our users of development tools try to write custom applications. There had to be a better way. So we took our years of experience supporting them and built this product.  Even Text/CSV file logging has special requirements:

• User configurable data delimiters 
• Use the data in Excel or for sharing with other applications
• Overwrite or append options
• Include headers based on tag names
• Custom header and footers using static text
• Multiple File spanning options (generating new files) 
• Flexible file naming 
• Full disk prevention

Wide Database Support, Flexible Configuration

• Native database connections for Microsoft SQL (including SQL Express), Azure SQL, and MySQL  
• Support for any ODBC compliant database
• Stored Procedures supported 
• Database connection keep alive for detecting down connections and reconnecting automatically
• Wizard driven configuration for new projects
• Direct configuration and import for power users 
• Use existing tables or create them automatically
• Flexible storage formats including mapping of values to columns

Ensuring No Data is Left Behind

If the connection to the database disconnects, store & forward ensures that data is buffered and sent to the database in the same order when the connection is restored. 

• User configurable memory buffer size or 
• Enable persistent local storage and forwarding with a single checkbox
• Customizable location for Store and Forward file location with advanced event tracing

You Deserve More than Basic Logging

• Schedule Based Logging - configure time windows for work shifts, daily, different groups of data at different times, natively integrated with Windows Task Scheduler 
• Event Based Logging - start and stop logging based on tags in your PLC or controller that indicate alarms, machine changeover, batch completion or anything
• Event Based File Spanning - use a tag in the controller to cause a new file to be generated 
• OPC Logging options - on data change, timer driven asynchronous or synchronous reads, or triggers as described above

HOW TO GUIDE

Your Data Is Important - Be Sure It's Stored - Writebacks to the Rescue

Anyone can receive data, throw it over the wall and hope it got stored. Our users were clear, they have data that cannot be lost.  They also want to know if the database connection is up. Users of OPC Data Logger often have logic in their PLCs/controllers that requires writing something back to confirm that the data has been received, only then will it fill up the data buffer again. Each application is different, so we built in Writebacks to address this handshaking need

• Write back a confirmation, based on your conditions, to any tag of any data type in your PLC/controller that you can access using OPC
• Supported with text/CSV and database logging
• Work with triggered/conditional logging
• Monitor database connection state and write values to PLC/controller if it goes down/returns
• Flexible choices for when a writeback is sent - different choices for text files and databases
