FIG. 1 is a block diagram showing one embodiment of a basic internal input/output section according to the present invention. 1...branch/insertion circuit, 2...control circuit, 3...
...Response identification signal detection circuit, 4...Reception buffer circuit, 5...Transmission buffer circuit, 6...Response detection circuit. Figures 2a and 2b show the flow of data within the block shown in Figure 1. Figure 2a shows the normal state of the slave station, and data from the transmission path is only branched and control signals are monitored automatically. Indicates that the data of the station is not sent to the transmission path, and b indicates that the data of the station is not sent to the transmission path.
It shows the flow of data when a response is received, and the data of the own station is sent to the transmission line. Figures 3a to 3d show the flow of data and control bits transmitted on the loop transmission path, where a is a non-communication state, so both the CONT signal and the SR signal are "0", and b is the signal from the master station. All slave stations are in the state of simultaneous paging, and all the slave stations receive the SR signal "1" and perform the calling operation.At this time, none of the slave stations has responded yet, so all CONT signals remain at "0". c indicates a state in which slave station B has responded, data from the master station is terminated at slave station B, and slave station B
data is newly sent to the transmission path, and at this time, slave station B changes the CONT signal to "1" and sends it out, and d indicates that the data goes around and the communication between the master station and slave station B is completed. Indicates the state in which the line is configured. SR...Call control signal, CONT...Response identification signal.
