6.3 Log-in on an IPC of the x800 device series (PC-based automation)
An RAS server runs on the IPCs. A user can log-in via modem/ISDN card on this RAS server. If
someone dials-in from a remote maintenance PC via this medium, the IPC executes a password
check and then activates the connection.
6.4 Computer access via Telnet
Telnet is a standard mechanism for experts to change system settings.
Telnet ...
• enables the access to the Controller data (example: Contents of the SD card);
• requires an existing local connection or remote connection.

Further information about the function and configuration of RAS servers can be found in
the following documentations:
• Industrial PC - Parameter setting & Configuration
• HMI EL 100 with Windows® CE - HMI for visualisation/with control technology
