Abstract

PURPOSE:To omit the useless data transmission at the transmission host and thus to ensure a smooth data transmission with other host by informing the fault situation of the host at the reception side to the transmission side when the data transmission is carried out among hosts. CONSTITUTION:The diagnosis system consists of node 10, host 20 (comprising CPU21, external memory 22, I/O terminal 23, etc.) and supervisory device 30 each. At the data transmission time, device 30 takes in transmission data 40 through node 10, draws out process code 44 at reception host 43 designated by transmission host 41, retrieves pattern information table 70 to decide unit pattern 71, checks pattern 71 to pattern 61 of fault information 60, decides incapability of starting for the reception host process shown at code 44 in case the both patterns mentioned above are in the ON state, sets fault display 47, and sends fault information data 50 back to the transmission side host following data 40. While in case the starting is possible for the reception host process shown at code 44, device 30 sends data 46 of data 40 to the reception side host to perform the reception process.
