Embedded Communication Services

Embedded communication services are IP-based communication services used in server mode on an embedded product (for example HTTP or FTP).

Recommendation to Disable Unused Services

To reduce the attack field, Schneider Electric strongly recommends that you disable any unused embedded service — for example HTTP and FTP — to close potential communication doors.

Disable Ethernet Services in Control Expert

You can enable/disable Ethernet services using the Ethernet tabs in control Expert. Tabs description is provided for each of the following platform:

• Modicon M340

• Modicon M580

• Modicon Quantum

• Modicon X80 modules

• Modicon Premium/Atrium

Set the Ethernet tabs parameters before you download the application to the CPU.

The default settings (maximum security level) reduce the communication capacities. If services are needed, they have to be enabled.
