<p>PURPOSE:To prevent the erroneous operation of the computer system by holding the information indicating whether the power make or break command of the system given from the remote control unit is made effective or not at the automatic operation control unit via the commant of the automatic operation control program. CONSTITUTION:System 1 gives the command to make the power make given from remote control unit 5 effective to automatic operation unit 2 in case the normal operation is secured for the check point process when the system has the automatic pause. At this moment, the power make effectiveness display lamp glows at unit 5. Then system 1 delivers the power break command of the system to power seuqencer 3. In that case, unit 2 havine the independent power source contunues the state under which the power make given from unit 5 is made effective even though the power supply is cut off for system 1. While in case the normal check point is not secured, system 1 gives the power break command to sequencer 3. In this case the state under which the power make from unit 5 is made ineffective is held by unit 2.</p> |
