receiving, from the client computer, a request for machine-related content;

transmission of information relating to machine state data to be acquired by the client computer in connection with the request for machine-related content;

receiving from the client computer the data acquired by the client computer;

generating of the requested machine-related content;

transmission of the machine-related content to the client computer;

receiving information relating to payment for content requested by the client computer; and

storing the information related to the payment.

2. The method according to claim 1, wherein the machine state data comprises real-time data acquired by the client computer.

3. The method according to claim 2, comprising the further step of receiving over the data communication link from the client computer a unique identification means associated with the client computer.

4. The method according to claim 1, wherein the machine state data comprises at least one of the group consisting of program data, servo data, motor data, converter data, position data and sensor data.

5. The method according to claim 1, wherein the received machine state data comprises data that is buffered in a data storage means by the client computer prior to its receipt by the host computer.

6. The method according to claim 5, wherein the step of receiving the machine state data comprises receiving machine state data transmitted to the host computer under time control.

7. The method according to claim 5, wherein the step of receiving the machine state data comprises receiving machine state data transmitted to the host computer under event control.

8. The method according to claim 1, further comprising the step of analyzing, in the host computer, received machine state data.

9. The method according to claim 1, comprising the further steps of:

generating a data structure to accommodate data relating to generated content;

storing, in the data structure, data representing the unique identification code; and

storing, in the data structure, data relating to the content.

10. The method according to claim 9, further comprising the steps of:

determining measured data relating to the content transmitted to the client; and
