<P>PROBLEM TO BE SOLVED: To enable time synchronization with other modules, using a simpler structure than a configuration individually performing time synchronization between one master and each of a plurality of slaves. <P>SOLUTION: A module is connected in series with other modules of an identical configuration. When a forward synchronous signal is input, the module outputs a synchronous signal to a nearest module in the subsequent stage, and at the same time, records a first time. Next, simultaneously when inputting a return synchronous signal, which is returned after passing the entire modules in the subsequent stages, the module records a second time, and outputs the synchronous signal to a nearest module in the preceding stage. Next, based on the first time and the second time, the module calculates a reference time. Then, when inputting a command signal, in which processing to be executed and an execution time indicative of a time to the execution of the processing are defined, the module executes the processing at a time obtained by adding the execution time to the reference time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
