The Ewon Flexy is able to perform local data acquisition using the serial or Ethernet port. The data acquisition process is built around a tagged database in which each tag is associated with an I/O server. The Ewon Flexy is able to perform data acquisition with the following protocols: Modbus RTU, Modbus TCP, Uni-Telway, EtherNet/IP, DF1, FINS TCP, FINS Hostlink, ISO TCP, PPI, MPI, Profibus, Mitsubishi FX, Hitachi EH, ASCII.
DATA LOGGING AND RETRIEVAL
Continuous data logging and buffering can be performed on every tagname. Each tagname can be logged on a fixed interval or on change (with deadband). Ewon stores tag data values (+ timestamp) in its internal database (up to 1,000,000 timestamp points) for statistical analysis and later review (historical logging) or to analyze recent trends (real-time logging).
The DataMailbox service of Talk2M is an online data buffer that allows the easy retrieval of Ewon gateway's historical data. Application developers can easily retrieve historical data from multiple Ewon gateways using the DataMailbox and a simple API call.
DataMailbox
The datalogging files can also be retrieved by FTP, HTTP or as an email attachment.
