Abstract
PURPOSE:To increase the usage efficiency of loop line and to reduce the transmission waiting time, by setting the block of a plurality of types of length according to the predetermined rules, in the system in which the block length of loop line of a block multiplex system is made variable. CONSTITUTION:A main device 2 and slave devices 3, 4, 5 are connected to a loop shape line 1. The main device and slave devices consist of the port shown in A and the main body shown in B. The constitution of block transmitted on the line 1 is that a synchronizing field 101 consisting of 8 bits, B, D, L, R fields 102-105 in one bit, S field 106 in 4 bits, and control field 107 in 8 bits are given and an information field 108 and an inspection field 109 in 16 bits follow after that. Further, the field identifying the block length of each block set with the specific rule is included at the predetermined location in the block.
