The Ewon Flexy offers many services to manage your data

LIVE data publishing


Besides the Easy and secure Remote Access functionality, Ewon Flexy acts as state-of-the-art gateway, reading data from I/O servers and publishing them with Modbus TCP, or OPC UA protocols. OPC UA uses a very powerful, secure and standardized technology for industrial data exchange, well deployed into the SCADA world or to communicate with OPC UA client in your factory.

Furthermore, the Ewon Flexy is the perfect gateway to publish live data with HTTPs and MQTT protocols towards any IOT platforms.

SMS_Email Relay


The Ewon Flexy provides full support for alarm triggering, acknowledgment, status and traceability. Alarm thresholds (4x) and parameters (activation delay, deadband 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 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, Mitsubishi FX, Hitachi EH, ASCII.



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.


The datalogging files can also be retrieved by FTP, HTTP or as an email attachment.



Interfacing serial or Ethernet devices with proprietary protocols is no longer a problem with the Ewon Flexy. The I/O Java server lets you create your dedicated I/O server using JAVA.

Basic Java


The Ewon Flexy can be fully scripted using BASIC scripting language or JAVA. You can design from simple to sophisticated automated tasks such as:

  • Reading and writing data via the serial port for industrial devices with proprietary protocols
  • Sending email messages
  • Replying to incoming SMS messages
  • Managing TCP/IP routing tables and features
  • Dynamically updating the Ewon unit configuration JAVA and BASIC scripts are intended to be used for deploying large Ewon based applications, since this provides flexibility and scalability


Interested in extending the local memory of the Ewon Flexy? Thanks to the Extended User Memory Card (EUM Card), the embedded file system can be extended to store historical logging data or camera images of an IP camera plugged into an Ewon. The EUM Card is an industrial Grade SD Card of 1 Gb with SLC (Single-Level-Cell) NAND Flash, designed for demanding industrial applications where customer data requires the highest level of reliability, durability, and data integrity.
