摘要： PURPOSE:To realize the transmission of a synchronizing data frame synchronizing with a main synchronizing signal by changing the length of a null data frame in response to the time difference between the transmission end time point of the synchronizing data frame and the main synchronizing signal. CONSTITUTION:When the incoming call of a token is detected at a station serving as a main station of synchronization, the null data frame is transmitted prior to the transmission of a synchronizing data frame. In this case, the time difference is detected by a timer 17 containing a register between the transmission end time point of the previous synchronizing data frame and the main synchronizing signal S1 of a station synchronizing signal generating circuit 20. Thus the length of the null data frame to be transmitted next time is calculated based on said time difference for production of the null data frame. This data frame and the synchronizing data frame are added to a transmission queue before the next token is received. Thus it is possible to transmit the synchronizing data frame synchronizing with the signal S1.

摘要： PURPOSE:To attain the transmission of a synchronizing data frame synchronously with a main synchronizing signal by using an idle data frame in a master station for signal synchronization and varying the length of an idle data frame in response to the time when the master station receives a token. CONSTITUTION:A station 11 being the master station for synchronization sends an idle data frame DS prior to the transmission of a synchronizing data frame D1 sent by its own station. The idle data frame DS consists of a fixed length part DSA and a variable length part DSB. The length of the variable length part SSB is adjusted in response to the time when the master station 11 receives a token. In order to adjust the variable length part, a means recognizing the transmission start time is provided to the master station 11. The length of the variable length part DSB is adjusted based on a time difference between a main synchronizing signal S1 and the transmission start time of the fixed length part DSA detected by the said transmission start time detection means. The signal synchronization with respect to the master station is applied at slave stations 12-1n by detecting the received time of the said synchronizing data frame D1.

摘要： PURPOSE:To avoid the synchronizing error of a slave station from getting larger by setting a flag representing defect of synchronization in a synchronizing data frame when a master station cannot send a synchronizing data frame. CONSTITUTION:A master station 11 for synchronization sends idle data frames DSA and DSB prior to the transmission of a synchronizing data frame D1. The length of the idle data frame DSB is varied in response to the time when the master station 11 receives tokens T1-Tn. Moreover, when the master station 11 cannot send the synchronizing data frame D1 due to delay of token arrival or the like, a flag representing defect of synchronization is set to the data field of the synchronizing data frame D1. Slave stations 12-1n, in detecting the said flag, disregard the synchronizing data frame D1 as the synchronizing signal. Since the signal synchronization of the slave stations is maintained with high accuracy, the stable signal synchronization is attained by using a token passing bus.

摘要： PROBLEM TO BE SOLVED: To transmit a transmission frame within a predetermined time without affecting communication of an Ethernet transmission station by specifying part of transmission stations as a synchronous transmission station that periodically transmits start timing of an implicit token path. SOLUTION: Real time Ethernet transmission stations RETH 101, 102,..., 10K, 111, 121, 131, 141, 11n-14n of the data transmission system and general Ethernet transmission stations ETH 20m,..., 20n, 210, 211-21n, 231-23n are interconnected by a transmission line L. Then a specific transmission station in the data transmission system is specified as a synchronous transmission station that periodically transmits the start timing of an implicit token path. Especially in the case that the synchronous transmission station is not yet decided at a leading point of time of the data transmission system, a new synchronous transmission station is specified among the transmission stations of the data transmission system.

摘要： PURPOSE:To continue periodical transmission and to improve reliability for a system even when abnormality occurs in a reference timing signal. CONSTITUTION:A synchronism control circuit 4 computes dummy frame length based on a token detection signal from a transmission control circuit 3 and the reference timing signal R1 from a reference timing signal generation circuit 1, and the transmission control circuit 3 transmits a dummy frame with the computed length by adding the dummy frame on the forefront of a data frame. Thereby, the transmission start time of the data frame of a station S can be mached with the period of the reference timing signal R1. At this time, monitoring circuits 7, 8 monitor a reference timing error and a dummy frame length error, and a monitoring operation command circuit 6 issues a command to transmit a synchronous station switching signal to a transmission control station 3 when the reference timing error occur. Hereinafter, a function as a synchronous control station is transferred from the station S1 to a station S3 that is a spare synchronous station, and the reference timing signal R2 is supplied from a separate reference timing signal generator 2 to the station S3.

摘要： PURPOSE:To maintain system function by inhibiting repeat normally in one of plural node stations connected into a loop by a pair of clockwise and counterclockwise transmission lines but starting repeat there if abnormality occurs. CONSTITUTION:Plural nodes 101-10n are connected into a loop by a counterclockwise transmission line 4 and a clockwise transmission line 4. One of nodes 10i, for example, the node 10n is defined as the switch node, and repeat of a signal from above is inhibited normally in the switch node. If data frames received by the switch node 10n in both directions within a certain time do not coincide with each other, lines are judged to be abnormal and repeat of the signal is started. Thus, system functions are maintained to prevent the complete stop of the system, and the abnormal position is located easily to quickly perform the abnormality processing.

摘要： PROBLEM TO BE SOLVED: To basically make disconnections at two places, to constitute two adjacent terminal stations when a network is initialized, and to make respective transmission stations operate individually and dispersedly in parallel during a recovery from a one-place fault to constitute terminal stations at new positions. SOLUTION: Two adjacent transmission stations among two or more transmission stations #ST1 to ST8 each having two communication ports for bidirectional communications serve as terminal stations, one of the transmission stations is a base point, and they are connected in a ring shape to constitute a double-ring network. The transmission stations #ST1 to #ST8 each decide whether a frame signal is received from an adjacent transmission station and when no frame signal is received, a route confirmation frame signal for route confirmation is transmitted to adjacent transmission stations. When a route confirmation frame is replied from either of the adjacent transmission stations, the transmission state sets itself as a terminal station instead of a current terminal station to make ring-shaped connections, so that the signal is not delivered to following transmission stations.
