Kind Code:
A
Abstract:
PURPOSE:To use the automated operation for a recovery operation after a failure factor being the cause of a jam is eliminated, in the case the jam occurs on the way of a sequential operation. CONSTITUTION:When a sequential automated operation is requested, an operation monitor part 3 compares operation logic 2 and a data base 8, and sends information 11 related to how far the operation train described in the operation logic 2 is completed, to a pre-condition evaluating part 4 and an operating part. The pre-condition evaluating part 4 considers a prerequisite corresponding to the completed operation to be always formed, and evaluates the pre-condition. Subsequently, in the case it is evaluated that the pre-condition is formed, an operation request signal 12 is sent to an operation executing part 5. The operation executing part 5 evaluates successively the operation logic after the completed operation and executes the operation.
