Abstract
A system for controlling data transmission comprises at least two control devices, a first common communication line to which each of the at least two control devices is connected, and a plurality of operation devices for carrying out respective processing operations. Each of the at least two control devices is connected with a different one of the plurality of operation devices and is provided with a priority rank depending on the one of the operation devices connected thereto. And each of the at least two control devices comprises: (i) a memory for storing at least one of command data and status data corresponding to the one of the operation devices connected thereto, (ii) a priority rank discriminator for discriminating whether a right to transmit data is requested by another one of the control devices having a higher priority rank, and (iii) a transmitter for transmitting the data stored in the memory to the first common communication line only if the priority rank discriminator discriminates that the right to transmit data has not been requested by another one of the control devices having the higher priority rank.
