METHOD FOR CHECKING PLURAL NODE CONDITION USING CHECK BITS AND SYSTEM THEREOF

摘要

The present invention relates to a technology for transmitting industrial large-amount object data. Particularly, a master node can selectively check information of a datagram according to a state bit as a check field area capable of checking an operation state of a slave node is added in a control frame and the master node checks whether the salve node normally operates. Therefore, load of an on-the-fly type network control system which is generated by calculation can be significantly reduced.
