System and method for remotely maintaining devices

A system for maintaining a device via a remote service computer, the system comprising:

• at least two sensor units operable to detect values of at least two monitoring parameters of the device;
• a first maintenance module connected with the at least two sensor units;
• a second maintenance module operable with the service computer;
• and
• an indicator device operable with the service computer to display information from the service computer,
• wherein the first maintenance module upon receiving data from the second maintenance module is configured to determine a monitoring parameter in response to a monitoring parameter request, to determine which one of the at least two sensor units is assigned to the monitoring parameter, to receive a monitoring parameter value from the assigned sensor, and to provide the monitoring parameter value to the second maintenance module,
• wherein the monitoring parameter is needed in a check routine used to troubleshoot or determine a cause of a problem in the device and is stored in the service computer, and
• wherein the second maintenance module is configured to automatically evaluate the monitoring parameter value to determine whether another monitoring parameter is needed in the check routine from the device and is configured to transmit a request for a subsequent monitoring parameter value to the first maintenance module based on the evaluation of the monitoring parameter value.

A method for maintaining a device via a remote service computer, the method comprising the acts of:

• automatically selecting a check routine based on maintenance data received from a device, the check routine being used to troubleshoot or determine a cause of a problem in the device;
• evaluating, by the remote service computer, the maintenance data within a framework of the check routine having a point in which a monitoring parameter is needed;
• requesting, by the remote service computer, the monitoring parameter from the device as a function of the evaluation;
• evaluating, by the remote service computer, a response, by the device, to the request for the monitoring parameter to determine whether another monitoring parameter is needed in the check routine or the check routine is completed;
• requesting by the remote service computer,the another monitoring parameter from the device as a function of the evaluation of the response;
• and
• indicating a result of the evaluation of the response.
