PURPOSE:To attain simplicity of constitution, improvement of the development efficiency and reduction of down-time by utilizing a function having a transmitter and only providing a maintenance interface section and a personal computer to the transmitter to realize the on-line monitor function. CONSTITUTION:A data station 42 is provided with a maintenance interface section (INF) 12, which is connected to a supervisory personal computer 13. A communication control section 8 converts an input data in parallel and generates a control signal at the same time. The data is transferred to the INF12 via another path, i.e., a monitor data bus 12A together with the control signal. The setting of trace start period of data, trace stop condition and delay or the like is executed via the personal computer 13. The INF12 interfaces with a transmission control section 9 via a transmission bus 11, has a transmission data trace memory 18, which fetches the data from the control section 8. A supervisory personnel inputs the information required for the trace of data from the personal computer 13, a CPU14 sets the condition to the memory 18 to control the trace to the memory 18. |
