Ewon and Siemens PLC

I would like to use an Ewon Cosy to access a Siemens CPU 315-2 PN/DP in China.

This piece of equipment has already shipped and is on site. What I would like to know is if it can be configured and sent to the customer and be ‘plug and play’, meaning they just connect the Ewon to the Internet and PLC so I can get connected. It looks like from the application note that I need to set up the PLC prior to connecting with the Ewon.

Any help you can provide is apprecitated.


The Cosy’s LAN IP need to be in the same subnet as the PLC. The PLC will also need to be connected in one of the LAN ports. If the reset of the Cosy is already setup you should be able to reach the PLC through the VPN connection.
