PURPOSE:To prevent the degradation of the function of the whole data way, by installing a station switch between a computer and a station. CONSTITUTION:Station switches 17 and 18 are installed between computers 12 and 15 and stations 13 and 16, respectively, and they are constituted in such a way that the connection between the computers 12 and 15 and stations 13 and 16 can be switched optionally. When a trouble occurs in one station 13 and transmission and reception of data become impossible, the computer 12 immediately judges the condition, cuts off the station 13 by switching the corresponding switch 17, and switches the connection to the station 16. Therefore, the computers 12 and 15 can make delivery and receipt of data with each station through the station 16. |
