6 Remote maintenance and diagnostics
For a remote maintenance of a Controller, the standard mechanisms for remote maintenance of a
PC can be used.
The standard mechanisms ...
• are based on Ethernet protocol and the protocols used for Ethernet;
• can be used between the Engineering/remote maintenance PC (Remote PC) and the
corresponding Lenze controller, IPC, or HMI.
The Engineering PC and remote PC are either connected directly to each other, or via remote
connection.
The following access mechanisms to a Lenze controller, Industrial PC, or HMI can be used ...
• with direct connection between the PCs within a local network;
• with a remote connection.
6.1 Remote maintenance with an external router
Establishing a remote connection requires an external router which establishes the remote
connection between two network segments.
The router has to be configured separately and has to be connected to the Lenze controller, IPC, or
HMI by one of the following types of connection:
• DSL
• ISDN
• Analog (modem)
Remote maintenance via an external router for instance is advisable if remote maintenance is
required for several controllers, IPCs, or HMIs.
