Hello
We are working on an application where there is an ewon flexy 201 that reads through its LAN port from an M251 PLC its process variables are read from I/O SERVERS MODBUS, they are displayed correctly in the EWON.
The publication of the variables to the SCADA (KepwareServer) is done with the OPCUA protocol, in the Ewon flexy 201 the OPC UA Server is declared, the Scada the OPC UA Client.
Declaring the same user in the OPC UA server and in the OPC UA client, the firmware used in the Ewon flexy 201 is version 12.1s0.
We test the open communication ports in the network from the Scada PC, verifying that the WAN address port is open.
The variables are visualized without problems in the SCADA.
The customer has not asked to update the Ewon flexy 201 firmware to version 14.6s0. With a new unconfigured Ewon Flexy we have updated to firmware version 14.6s0, performing the same configuration as Ewon Flexy with version 12.1s0.
But the results have not been correct, because when trying to export the variables in KepwareServer it gives us an error when verifying the port test, it is verified that it is not open, despite having the same configuration.
There are problems when migrating to firmware 14.6s0, because we are working with ewon flexy 201 and with the same configurations.
