context_page_description: Ignition is an Integrated Software Platform for SCADA systems released by Inductive Automation in January 2010. It is based on an SQL Database-centric architecture. Ignition features cross platform web based deployment through Java Web Start technology. The Ignition platform has three main components: the Ignition Gateway, the Designer, and runtime clients. Independent modules provide separate functionality in any or all of the platform components. Ignition SCADA modules provide features such as: Real-Time Status Control, Alarming, Reporting, Data Acquisition, Scripting, Scheduling, MES, and Mobile support.
context_section_description: SQL Bridge is an OPC based Middleware product that bridges the gap between industrial PLCs and SQL Databases. It is a drag and drop application that does not require scripting or programming for configuration.
  Transaction groups are used to log data, synchronize PLCs, track downtime and manage recipes. Such groups support stored procedures, flexible execution scheduling, and triggering for precise control and monitoring. Data logging can be achieved with transaction groups or SQLTags History.
  Store-and-Forward is an engine that buffers SQL database writes to memory and caches them to a local disk when an external database connection is unavailable. Upon reconnection the data is forwarded to the server in aggregated time-efficient batches.
  The SQL Bridge module was created in January 2010 to replace the final version of FactorySQL in the 4.x.x series.
