Talisen’s ESP is complete with a robust data integration middleware component called the Data Acquisition Gateway (DAG). The DAG is a multi-tiered data collection and distribution framework designed for integration with building automation system (BAS) protocols, as well as other TCP/IP based protocols.
Talien’s gateway consists of a system scheduler to allow polling of systems at different intervals and data access is organized as a collection or protocol and device drivers. The DAG supports a number of standard TCP/IP IT protocols such as SQL, (s)FTP, HTTP(s), OPC, etc., as well as standard BAS protocols such as BACNet/IP, Modbus/IP. The modular protocol/device driver architecture allows for easy extensibility.
