摘要 |
A basic system of an NC unit and a distributed type remote I/O unit executes time division signal transaction through a half-duplex serial communication line, and in case where the distributed type remote I/O can not detect a receiving start state of a transmission frame from the basic system of the NC unit for a specified period of time, output is reset, and the basic system of the NC unit checks a type of and data setting in the distributed type remote I/O unit, and also checks a result for an input/output test and the current situation of communication according to a header pattern of a transmission frame.
