eWON 500 is the versatile Serial-to-Ethernet gateway for industrial applications. With its transparent gateway, eWON 500 interfaces any serial PLCs or any serial automation devices to Ethernet. This allows them to be connected to Ethernet platforms and software (OPC servers, workstations with PLC programming software, etc...) for data polling and/or maintenance.

eWON 500 also performs data acquisition from PLCs or automation devices in various protocols, including raw ASCII mode. Additionally, it provides an alarm management system.
Typical Applications
  • Transparent Gateway
  • Configurable Gateway
  • Programmable Gateway
Transparent Gateway
As a Transparent Gateway, eWON is the link between your serial devices or PLCs and the Ethernet LAN in your company allowing transparent access from any local workstation. Much more than a simple protocol converter, because it acts at a gateway level and is fully compliant with TCP/IP RFCs, eWON offers unmatched reliability even with complex serial bus architectures.
Configurable Gateway
As a Configurable Gateway, eWON polls serial PLCs or devices at defined intervals to feed its internal memory tags with live data.  It then publishes this information on the LAN in Modbus/TCP and SNMP, making it available to higher end applications such as SCADA, Historian, OPC servers and ERPs.  In addition, eWON watches those values and sends email warnings or SNMP traps in case of alarms. Supporting over 20 concurrent Ethernet sessions, eWON’s hardware and firmware puts forward a robust solution with outstanding performances.
Programmable Gateway
As a Programmable Gateway, using scripts in BASIC language, you take full advantage of eWON’s absolute versatility.  With just a few lines of simple code, eWON interfaces any ASCII serial device, sending commands, decoding replies, feeding its memory tags with the values and making the equipment, the measurements and the events visible on the LAN in Modbus/TCP, SNMP or from any standard web browser.
