Historically, PC-Topp would either calculate the duration of an order by itself - based on conversion machine parameters - or the user could tell the system how long he estimated the duration of the order from start to end. Of course, that duration could also be received from the host system in the Order Data Transfer.

While this seemed sufficient for planning purposes, this approach had the disadvantage that the set-up time was always based on machine parameters even for orders with a manually given duration. This made it impossible to compare the actual set-up time to the target time for such orders where the set-up was more difficult than for a normal order.

Therefore, it is now possible to specify also the set-up time for an order, either manually or in the Order Data Transfer.
This opens the following options for the calculation of the total duration of an order.

Set-up time calculated Based on number of colors and die-cut or not		Run time calculated Based on machine's average speed
Set-up time given By host or manually		Run speed given (Indirectly based on total duration)

Obviously, the run speed does not appear in the order data or in the data transfer; it is specified indirectly by giving the total run time to maintain compatibility with earlier versions of the order data transfer.

This means that instead of sending a set-up time of 27 minutes and a speed of 5000 / h, the host must calculate the run duration based on the quantity (e.g. 10000) and give PC-Topp the result for the total time (0'27 + 2'00 = 2'27).

Future improvements are planned: In a future version PC-Topp will be able to use a given set-up time and speed per article, or base the entire calculation on past experience with previous orders for that article.
