PURPOSE:To utilize the titled system for operation simulation at debugging and the supervision of periodic operation and to investigate quickly causes of a fault by allowing a data line supervisory equipment to supervise data on a data line and a program running history of a data transfer equipment at the same time normally in parallel. CONSTITUTION:The data line supervisory equipment 1 consists of a line monitor circuit 2, an address monitor circuit 3, a data storage circuit 4 and a data analysis circuit 5, the circuit 2 is connected to a data line 10 between data transfer equipments 8, 9, the circuit 3 is connected respectively to the equipments 8, 9 through address information lines 11, 12. The circuit 2 collects transfer data and transfers it to a storage circuit 4. The circuit 3 collects the address information representing the running history of the control program from both the transfer equipments and transfers the result to the storage circuit 4. Based on both the said data, the analysis circuit 5 analyzes the line data at all times to supervise the dissidence of data transfer flow and a data error. Further, the maintenance personnel uses the said address information to analyze the operation of both the transfer equipments at data error.
