MULTIPLEX TRANSMISSION EQUIPMENT

摘要

PURPOSE:To prevent the adverse influence that is caused by the non-cyclic control information and given to the cyclic control information which is transmitted through a communication line in a multiplex mode by connecting plural node parts which transmit of fetch the control information to the communication line through which the control information is transmitted in a multiplex mode. CONSTITUTION:A cyclic information signal line 11 and a non-cyclic information communication line 12 are set individually to each other. Then plural nodes are connected to the line 11 for transmission or fetch of the cyclic control information. Meanwhile plural nodes are connected to the line 12 for transmission of fetch of the non-cyclic control information respectively. Furthermore a column node 30 and a meter node 31 are connected to both lines 11 and 12 to selectively transfer the cyclic and non-cyclic information between both lines 11 and 12 as necessary.
