Fig. 4-6 Example: Connection structure of the remote diagnosis
Remote diagnosis sequence
A machine manufacturer who provides this service has selected an appropriate
topology for a tunnel connection and will provide support when setting up the
remote diagnosis.
The relevant "Ping server" on the remote PC must be activated for this purpose.
This server has the task of accepting the incoming "Ping" data (e.g. serial number)
of the requesting machine and registering the IP address of the requesting
machine. If this server application is not provided by the service provider, it is
possible to configure the RCS viewer application so that a simple "Ping" server
process can be started on the RCS Viewer. The IP address, the port and the
protocol used for this Ping server are specified by the service provider and must be
set on the machine.
The remote diagnosis is initiated by the machine. The NCU 7x0 is connected to the
appropriately configured router via an Ethernet cable and starts the remote
diagnosis process via the operating interface. The NCU 7x0 then sends cyclically
preset "Ping" data to the remote PC and waits for its response. The transmission of
the "Ping" causes the router to establish the connection (e.g. switched ISDN
connection).
When the response is received from the remote PC, the NCU 7x0 is ready for the
data communication for the remote diagnosis. For this, a server process is started
on the NCU 7x0 which is responsible for the exchange of graphic information to the
remote PC and the keyboard inputs from the remote PC.
The exchange is performed via the TCP/IP protocol and a "permanently" agreed
port. A so-called "Viewer" application (mmcR.exe) is installed on a remote PC as
communication partner. From now on, all further activities will be initiated by the
remote PC.
