access via proxy not work
Answer off Thomas Hora
@msoenen Only the device on the Modbus TCP channel, not the whole PLC.
The proxy configuration looks good. Did you upload the configuration (right click on PLC - PLC operation - PLC setup)? If you are connected to the PLC via the LAN and start the debug mode, check the Proxy information in the System Status.
What should we see in the status system?
Should we also open ports 6677 on the router?
@msoenen The status should be CONNECTED in the PROXY field. If you see disabled, then the configuration is not done properly. Anyway, Mervis requires the port 6677 to be allowed for outgoing connection in order to make the proxy work.
