When using for the first time a PLC "M580xxxx" , the FTP and HTTP ports are CLOSED.

=> As a consequence, on a "virgin" M580 it is NOT possible to:

• Connect UnityLoader.
• Open the web page of the CPU.

This new policy will apply from BMeP580xxxx FW version 2.20.

To enable these ports, just download an application in which the option "FTP" and/or "HTTP" are enable. (security tab)
For M580 PLC range Firmware over 4.xx, the tool to use is no more Unityloader but "Ecostruxure Automation Device Expert".
