PURPOSE:To easily obtain restorations and to reduce load of the processing device so that the cost is reduced, by detecting dissidences between discrimination signals added to data, in a processing system which displays transferred data in its terminal equipment. CONSTITUTION:Data D to be delivered from a processing device 25 is delivered from the device 25 after command codes S are added, and then, two kinds of dis- crimination signals A and E are alternately added to before and after the command code S and to the tail of the data D. A terminal equipment 1 stores the signals in a storage section 6, compares and discriminates a series of discrimination signals, and, when different kinds of discrimination signals A and B are detected between the discrimination signals, displays the command code S in the storage section 6 in a display section 3 after reading out. Therefore, operators can recognize occurrences of abnormalities and can understand that up to what point of time the data are correct, by watching displays of the command code S and data D. |
