PURPOSE:To eliminate the need for the designation of the machine number of many sets of slave devices at each start of transmission, by providing a set means setting the registering the machine number of the slave sets in the master set by group. CONSTITUTION:In setting the machine number of slave devices S1-S3 by group at a master device M, a numerical information input means 1 is operated and a slave set number is inputted to a CPU5 via an encoder 2. To designate to which group this slave set belongs, a group key among group designation keys G of a function key group 3 is depressed to indicate to the CPU5 to which group the slave set inputted before belongs. The CPU5 inputs and stores the slave set number to a prescribed area (b) of a designated memory 7 by an address counter 8 via an input/output controller 9. |
