ABSTRACT:
A local area network system in which a logical ring is formed by at least part of said node stations to pass a token frame from one station to another in an endless and cyclic fashion allowing each of said node stations which has received is allowed to transmit data, and said data comprises event data. Since only the stations holding the token are allowed to transmit cyclic data and event data, each station is not required to be equipped with a monitoring timer so that not only the LAN can be constructed economically but also transmission efficiency can be improved through speed up in determining the completion of data transmission.
