6.2 Remote maintenance with a separate remote PC
[6-1] Sample configuration: Remote maintenance of a Controller 3200 C
• The Engineering PC accesses the separate remote PC via an internet connection.
• The remote PC is connected to the Lenze controller, IPC, or HMI via Ethernet.
• On the remote PC, the Lenze engineering tools (such as »EASY Starter«, »PLC Designer«) are
installed.
• The remote PC can be controlled from the Engineering PC via screen redirection.
 »Virtual Network Computing (VNC)«: Redirecting screen contents/entries ( 56)
The screen contents of the controller, IPC, or HMI are redirected to the remote PC. This makes it
possible to actuate the functions of the device, for instance the same programs as for the local
connection via Ethernet can be used.
A basic overview of the different dial-in programs can be found in the following section.

Note!
Setting a remote maintenance may endanger the IT safety!
• This is particularly relevant if the remote PC is connected to an Ethernet network.
• Contact your IT administrator to take the necessary safety measures.
