<p>PURPOSE:To prevent a slave device from being disabled to access in a sheathed state and to effectively utilize a computer resource by adding sheath forced reset circuits to respective master circuits. CONSTITUTION:Sheath forced reset circuits 3, 14 are respectively built in the 1st and 2nd master devices 1, 12 and are connected to a slave sheathe control circuit 21 in the slave device 22 through sheath forced reset lines 7, 18. When the device 1 is stopped by any abnormality in the sheathed state of the device 22, the device 12 detects the abnormality and the circuit 14 built in the device 12 instructs the circuit 22 to reset the sheathed state through the line 18. The device 22 resets the sheathed state applied from the device 1.</p> |
