eWON Flexy 101

Secure VPN Remote Access

The eWON Flexy embeds VPN capabilities and compatibility with Talk2M and eFive. This allows highly secure remote access for remote monitoring, troubleshooting and application tuning. The Flexy 20x adds routing capabilities that allows remote access to any serial or Ethernet devices behind the eWON Flexy. It enables PLC remote maintenance, remote IP camera, remote HMI monitoring, etc.

Data Acquisition

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, Mistubishi FX, Hitachi EH, ASCII.

Alarm Management and Notification

The eWON Flexy provides full support for alarm triggering, acknowledgment, status and traceability. Alarm thresholds (4x) and parameters (activation delay, deadbang value) can be set on every tagname. The complete alarm cycle (ALM, RTN-return to Normal, ACKnowledgment, END) is traced and available for monitoring and analysis. Alarm notification can be performed by email, SMS, SNMP trap and/or put FTP.

Data Logging and Retrieval

Continuous data logging and buffering can be performed on every tagname. Each tagname can be logged on fixed interval or on change (with deadband). eWON stores tag data values (+timestamp) in its internal database (up to 1,000,000 time stamped points) for statistical analysis and later review (historical logging) or to analyze recent trends (real-time logging). The datalogging files
can be easily retrieved by FTP, HTTP or as an e-mail attachment.

Web Server HMI

The eWON Flexy has an integrated web server for configuration and monitoring purposes. The eWON Flexy provides a highly cost effective HMI, viewable wherever you are through any standard Web browser interface.
