Abstract
PURPOSE:To ensure a highly efficient communication of data, by monitoring the using state of by-pass route of each data station that constitutes a loop network. CONSTITUTION:The on/off mode of by-pass route is obtained through a register 13 for each station by means of a control line which transmits the control information between the data stations. This information is put into a frame produced by a frame producer 11 and is stored in a memory 16. The stored on/off mode information of the by-pass route is displayed selectively and then monitored. In such a way, the state of by-pass route can easily be monitored for other data stations.
