<p>PURPOSE:To improve the work efficiency by constituting the titled controller so that whether a down-loaded NC command data has been used up to the present after have been updated or not is shown to an operator. CONSTITUTION:When an updated NC command data has been stored and saved in an NC file of a cell controller, the first storage means (a) stores its time as a final updating time by allowing it to correspond to the NC command data. When the NC command data has been down-loaded from the NC file, the second storage means (b) stores it time as a down-load time by allowing it to correspond to the NC command data. When the NC command data is down-loaded, a new/old discriminating means (c) reads out the final updating time and the final down-load time of the NC command data, from the first storage means (a) and the second storage means (b) and compares whether they are new or old. In such a way, in case it has been discriminated that the final updating time is newer than the final down-load time, a warning means (d) can give a warning to an operator.</p> |
