Flexy are available in two series. The Serie 100 has been designed for simple and cost effective Remote Data Collection application and doesn’t provide routing capability between Lan and VPN interface. The Serie 200 provides full features.

Data Acquisition Protocols
OPC UA, MODBUS/RTU, MODBUS/TCP, Unitelway, DF1, PPI, MPI (S7), PROFIBUS (S7), FINS Hostlink, FINS TCP, EtherNet/IP™, ISO TCP, Mitsubishi FX, Mitsubishi Melsec, Hitachi EH, ASCII, BACnet/IP. Stored in max 2500 internal tags.
Data Publishing Protocols
Alarms notification by email, SMS, FTP put and/or SNMP traps.
4 Thresholds : low, lowlow, high, highhigh + deadband and activation delay.

Internal database for data logging (real-time logging and historical logging up to 1,000,000 timestamps). Historical data can be exported to DataMailbox or transferred by FTP or email.

SD card reader

A/ for easy commissioning (firmware upgrade, backup, Talk2M registration) B/for Extended User Memory.

VPN Tunnelling

Open VPN either through UDP 1194 or TCP 443 ( HTTPs port).

VPN Security VPN sessions are end-to-end encrypted using SSL/TLS protocol. Communications between the remote user and the eWON are fully encrypted using the SSL/TLS protocol, thereby ensuring data authenticity, integrity & confidentiality. Indeed, all users and eWON units are authenticated using x509 SSL certificates and end-to-end traffic is encrypted using strong symmetric & asymmetric algorithms that are part of the SSL/TLS protocol cipher suite.

Script interpreter for Basic language, Java 2 Standard Edition environment.


Embedded real-time clock, manual setup via http or automatic via NTP.

File Management FTP client and server for configuration, firmware update and data transfer.

Flexy is OPC UA Ready

Securely enable your data from your Machines to your Factory Enterprise System!

OPC UA is a communication protocol for a secure and reliable exchange of data in industrial automation applications. OPC UA has the huge advantage of being platform-independent. It ensures the seamless flow of information among devices from multiple vendors. From sensors to cloud, OPC UA is fully scalable, object oriented and allows to use structures or models which makes governance and maintenance much easier.

PLC 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.

Connection to IoT platforms

You can connect your Flexy to different clouds, including Talk2M
Direct connection to Azure IoT Hub (Microsoft) and AWS IoT (Amazon) are also possible, even if you want to use Talk2M, our Flexy is certified to connect to these other clouds
Data are stored locally so you can get started today, choose an external cloud and you won't be locked in.
