Communication with eWON industrial routers

Basic information:

The eWON company is one of the leading manufacturers of industrial VPN routers for remote device management. The eWON Flexy line of industrial routers is fully compatible with PLCs produced by renowned manufacturers: Siemens, Allen-Bradley, Modicon, Wago, ABB, Omron, Hitachi, Mitsubishi, VIPA, etc. ..

Compact industrial router eWON CD allows remote connection to devices (using VPN) and it is also possible to use it as hardware data concentrator (the 2000 family for online data, the 4000 family also provides logging capability into local memory).

The modular industrial router eWON Flexy allows (VPN) connectivity to remote sites where communication technologies may change in time, or where it is required to communicate with devices using various communication protocols. The Flexy basic unit can be complemented with additional modules, e.g.: LAN module, modem (3G, 4G, PSTN...), serial link (RS232/485/422), WiFi module (803.11 b, g, n), IO module (8x DI, 4x AI, 2x DO) etc. The Flexy also has internal memory for local datalogging.

eWON CD and eWON Flexy features:

These routers can read data from various devices using built-in communication protocols and also enable the data to other superior devices by the Modbus protocol or by the SNMP protocol (in principle, these devices can also be used as hardware communication converters from various protocols to Modbus or SNMP), by FTP or by HTTP in XML format. Another option is to make data available by means of the integrated OPC UA server.

eWON Flexy and eWON CD of the 4000 family can also log the data locally (as datalogger). It is possible to keep log of more than 1 million values with a timestamp.

Supported communication protocols: Modbus RTU, Modbus TCP/IP, Uni-Telway, EtherNet/IP, DF1, FINS TCP, FINS Hostlink, ISOTCP, PPI, MPI, PROFIBUS, Mistubishi FX, Hitachi EH, ASCII, BACNET/IP

VPN support: secured remote access via VPN

Alarm notification: E-mail, SMS, SNMP TRAP, put FTP

HMI Web server: integrated user Web server for remote monitoring

Communication of eWON router with PROMOTIC SCADA software

Reading online data:

Reading current data is possible if the PROMOTIC application runs in common local network with the eWON device, or if the eWON device is directly visible on the internet (unsecure communication), or if the eWON device is connected via VPN (secure communication managed by the eCatcher software).

Communication by the Modbus protocol:

This way of data reading from eWON router appears to be the simplest option. In order to make this work, it is necessary to configure the Modbus TCP server in the eWON router. Visibility of each eWON tag via Modbus TCP must be enabled (in "Tag visibility" section) and corresponding registry address must be set.

For reading realtime data by the Modbus TCP protocol it is handy to use the preconfiguration:

Preconfiguration "PmModbusMr - eWON (Communication by the Modbus protocol) - Communication set with data and panel"

Communication by the HTTP protocol:

The EBD (Export Block Descriptor) can be used in order to read online (and also historical) data from the eWON device. The data is read in CSV format.

For reading realtime data by the HTTP protocol it is handy to use the preconfiguration:

Preconfiguration "eWON - Communication with eWON industrial routers - Communication set with data and panel"

Reading historical (offline) data:

Historical data can be read both localy and remotely. The eWON device can also save the data into a public cloud service by using the Talk2M internet service or into its own cloud managed by the eFive VPN Server.

Communication by the HTTP protocol:

The EBD (Export Block Descriptor) can be used in order to read historical (and also online) data. The data is read in CSV format.

For reading historical data by the HTTP protocol it is handy to use the preconfiguration:

Preconfiguration "eWON - Communication with eWON industrial routers - Communication set with data and panel"

Reading data from Talk2M cloud:

The DataMailbox Web API can be used in order to read historical data from Talk2M cloud in JSON format.

For reading offline data from Talk2M cloud it is handy to use the preconfiguration:

Preconfiguration "eWON - Communication with cloud service Talk2M DataMailbox - Communication set with data and panel"

Reading and writing data into devices connected to Talk2M cloud via M2Web API interface:

The M2Web API allows to read and write on-line data into devices connected to Talk2M cloud.

For reading on-line data and writing into devices connected to Talk2M cloud with M2Web API interface it is handy to use the preconfiguration:

Preconfiguration "eWON - Communication with cloud service eWON Talk2M by means of the M2Web API interface - Communication set with data and panel"
