Usage the various communicating channels with multilevel data broadcasting; Service in industrial conditions (-40…+60°С).

2. The level of supervisory control 

Infolook.DBiz – is the object-oriented platform for creating data handling systems in real-time. The handling includes different calculations with data of objects: archiving, alarm generation, import and export data from external systems, etc. A feature of the platform is the ability to increase its functional by users. 

This is a software for data acquisition from industrial devices through the different communication protocols and for data transfer to external system via OPC DA protocol.
The software allows to receive the data from industrial devices supported protocols РТМ and Modbus, adjust routes to devices access, configure the speed of data receiving by polling queues, build and display the historical data received during the data acquisition.

3. The Workstation of process engineer based on software DNM Analyzer
