Flexy read data from PLC's
Introduction
The eWON Remote Data Solution is built around the advanced data services of the eWON products such as the eWON Flexy.
In this video series, learn how to configure an eWON Flexy to acquire data from Ethernet and serial devices, manage alarms, log data over time, publish data with Modbus, SNMP, and OPC-UA, and create powerful remote dashboards.
IO Server
IO Servers tell the eWON Flexy how to communicate with different field devices. The eWON Flexy supports a wide variety of industrial protocols.
In this video series, learn about the Flexy’s embedded IO Servers and their configuration.
Lessons
Configure an IO Server
The eWON Flexy understands multiple IO protocols. All those protocols are handled by an IO server.
Learn how to display and configure an IO server to establish a proper communication with field devices.
OPC UA Client - Communication settings
The eWON Flexy can act as an OPC UA client to retrieve data from 3rd-party devices (which are the OPC UA server).In the settings of the Flexy, you'll need to set up all communication related information (certificates, user management, ...). Check how to deal with it!
OPC UA Client - Authentication settings
The eWON Flexy can be used as an OPC UA client to retrieve tags from an OPC UA server.In the settings of the Flexy, you'll need to configure the authentication process. CHeck how!
Tags
Tags are data elements monitored by the eWON Flexy from a data source such as PLC registers or the Flexy’s local inputs and outputs.
In this video series, learn how to create tags for different data sources and how to view and change those tags through the Flexy’s web interface.
Lessons
Tag Management
Tags in an eWON Flexy are used to received or set values from / to third-party devices that are linked to the eWON device.
Learn how to access the tags page of an eWON Flexy and receive explanation on the interface of this page.
Create a MEM Tag
The eWON Flexy is capable of dealing with Memory tags which are stored in the memory of the eWON itself.
Learn how to create and manage MEM tags on an eWON Flexy.
Create a eWON Tag
The eWON Flexy can communicate with external devices through tags. These tags can also represent values, status, … of the eWON device itself.
Learn how to set up an eWON tag to access information on (for example) DO, AI, …
Create a Tag linked to an IO Server
The eWON Flexy can communicate with other devices through tags.
Learn how to set up a tag in order to communicate with a device plugged in the eWON Flexy.
Create an OPC UA Tag
The eWON Flexy can act as an OPC UA client, retrieving data from 3rd-party devices (which are the OPC UA servers).
In this video, learn how to create a Flexy tag linked to OPC UA protocol.
