<p>PURPOSE:To eliminate a remarkable change of a software as option, and also, to reduce current consumption at the time of stand-by mode by connecting a second sub-CPU operated by an exclusive power source, to a main CPU and a first sub-CPU which are stopped by disconnection of a main power source. CONSTITUTION:When a power source switch of a work station is turned off, a power source control part 4 cuts off supply of a main power source 6 to a main CPU 1 and a first sub-CPU 2, and executes continuously power source supply to a second sub-CPU 3 from an exclusive power source 7. Therefore, a second sub-CPU 3 executes monitoring of a power source turn-on command issue, etc., from other work station. Also, when a frame from other work station is received in a stand-by mode, a power source turn-on instruction is executed to the power source control part 4. When the instruction from this second sub- CPU is received, the power source control part starts supply of the main power source 6 to the main CPU 1 and a first sub-CPU 2, and transfers LAN control to a first sub-CPU 2.</p> |
